Pro 92 500 Channel Portable Trunking Scanner

Owners Manual

Features

Your RadioShack PRO-92 500-Channel Portable Trunking
Scanner is one of a new generation of scanners designed
to track Motorola ® Type I and Type II (such as
Smartnet ® and Privacy Plus ® ) and hybrid analog trunking
systems, plus GE/Ericsson (EDACS ® ) and EF Johnson
(LTR ® ) type systems, which are extensively used in many
communication systems.

Trunking communications systems let a large group of 2-
way radio users (or even different groups of 2-way radio
users) efficiently use a set of frequencies. Instead of selecting
a specific frequency for a transmission, the user
simply selects a talk group. The trunking system automatically
transmits the call on the first available frequency,
and also sends a code that uniquely identifies that transmission.
Since the trunking system might send a call and its response
on different frequencies, it is difficult to listen to
trunked communications using a regular scanner. The
PRO-92 monitors the data sent with a 2-way radio transmission,
so you can hear the call and response for that
user and more easily follow the conversation.
The scanner also lets you scan conventional transmissions,
and is preprogrammed with service search banks
for convenience. By pressing a single button, you can
quickly search those frequencies most commonly used
by public service and other agencies without tedious and
complicated programming.

This scanner gives you direct access to over 33,000 frequencies
including those used by police and fire departments,
ambulance services, government agencies, air,
and amateur radio services.

Your scanner includes these special features:

Simultaneous Trunking Operation  tracks three
trunking systems, LTR, Motorola, and EDACS at the
same time, as well as conventional systems.

Text Input  lets you input a text label for each channel,
talk group ID, bank, or other memory so you can easily
know about the transmission you are hearing.

Subaudible Tone Decode  decodes and displays the
Continuous Tone Coded Squelch System (CTCSS) tone
signal being transmitted.

Digital Subaudible Tone Decode  decodes and dis-plays
the Digital Coded Squelch (DCS) being received.

12-Character, 4-Line, Dot-Matrix Display  shows you
detailed operating information and lets you easily pro-gram
the scanner.

Data Cloning  lets you transfer the programmed data
to another PRO-92 scanner. You can also upload or
download the programmed data to or from a PC using an
optional interface kit.

10 Channel-Storage Banks  let you store 50 channels
in each bank to group channels so calls are easier to
identify.

Triple Conversion Superheterodyne Receiver  virtually
eliminates any interference from intermediate frequency
(IF) images, so you hear only the frequency you
select.

Hyperscan TM and Hypersearch TM  the scanner scans
at up to 25 channels per second and searches at up to 50
steps per second, to help you quickly find interesting
transmissions.

Page 3


60 Preprogrammed Frequency Ranges - let you
search for transmissions within preset frequency ranges
or within ranges you set, to reduce search time and select
interesting frequencies more quickly.

Scan Delay - delays scanning for about 2 seconds be-fore
moving to another channel in conventional mode, so
you can hear more replies that are made on the same
channel.

Priority Channel - you can set the scanner to check
one channel every 2 seconds so you do not miss impor-tant
calls.

Signal Attenuation (Attenuate) - lets you program
each memory to reduce the scanner’s sensitivity to strong
local signals, to reduce interference or noise caused by
these signals.

Weather Alert - automatically sounds the alarm tone to
advise of hazardous weather conditions when it detects
the alert signal on the local National Oceanic and Atmospheric
Administration (NOAA) weather channel.

Weather SAME Decode - displays the weather event
text so you can see the reason for the alert.

Lock out Function - lets you set your scanner to skip
over specified channels or frequencies when scanning or
searching, and skip over IDs when tracking trunked systems.

Key Lock - lets you lock the scanner’s keys to help prevent
accidentally changing the scanner’s programming.

Flexible Antenna with BNC Connector - provides excellent
reception and is designed to help prevent antenna breakage.

Memory Backup - keeps the frequencies stored in
memory for an extended time even without a battery.


Page 4


Three Power Options - let you power the scanner with
internal batteries (non-rechargeable batteries or re-chargeable
batteries). You can also use an AC adapter
(not supplied) or power the scanner in a vehicle using a
DC adapter (not supplied).

Supplied Police Call Trunking Guide - provides a
quick reference to public safety trunking radio systems in
the United States.

Your PRO-92 scanner can receive these frequencies:


 29-54 MHz
 108-136.9875 MHz
 137-174 MHz
 380-512 MHz
 806-823.9875 MHz
 849-868.9875 MHz
 894-960 MHz

This Owner’s Manual also includes the section A General
Guide to Scanning on Page 65 to help you target frequency
ranges in your service area so you can search for
a wide variety of transmissions.

FCC NOTICE
Your scanner might cause TV or radio interference even
when it is operating properly. To determine whether your
scanner is causing the interference, turn off your scanner.
If the interference goes away, your scanner is causing
the interference. Try the following methods to eliminate
the interference.


 Move your scanner away from the TV or radio.
 Connect your scanner to an outlet that is on a differ-ent
electrical circuit from the TV or radio.
 Contact your local RadioShack store for help.

Page 5


If you cannot eliminate the interference, the FCC requires
that you stop using your scanner.

This device complies with Part 15 of the FCC Rules. Operation
is subject to the following conditions: (1) This de-vice
must not cause harmful interference, and (2) this
device must accept any interference received, including
interference that may cause undesired operation.

Note: Mobile use of this scanner is unlawful or requires a
permit in some areas. Check the laws in your area.

SCANNING LEGALLY
Scanning is a fun and interesting hobby. You can hear
police and fire departments, ambulance services, government
agencies, private companies, amateur radio services,
aircraft, and military operations. It is legal to listen to
almost every transmission your scanner can receive.
However, there are some electronic and wire communications
that are illegal to intentionally intercept. These include:

 telephone conversations (cellular, cordless, or other
private means of telephone signal transmission)
 pager transmissions
 scrambled or encrypted transmissions

According to the Federal Electronic Communications
Privacy Act (ECPA), as amended, you could be fined and
possibly imprisoned for intentionally listening to, using, or
disclosing the contents of such a transmission unless you
have the consent of a party to the communication (unless
such activity is otherwise illegal). These laws change
from time to time and there might be state or local laws
that also affect legal scanner usage.

PREPARATION
POWER SOURCES


You can power your scanner from any of three sources:


 internal non-rechargeable batteries or rechargeable
batteries (not supplied  see Using Batteries)
 standard AC power (with an optional AC adapter see Using AC Power on Page 14)
vehicle power (with an optional DC adapter see Using Vehicle Power on Page 15)

Notes:


 Connecting an AC or DC adapter to the scanner disconnects
internal batteries when you use the supplied
non-rechargeable battery holder, but it does not
disconnect internal batteries when you use the supplied
rechargeable battery holder.
 If you install the rechargeable battery holder, you can
operate the scanner and recharge the rechargeable
batteries at the same time. See Using Batteries
below and Charging Rechargeable Batteries on
Page 13.
 If the scanner stops working properly after connecting
it to power, try resetting it. See Resetting/Initializing the Scanner
on Page 75.

Using Batteries
You can power the PRO-92 with six AA batteries. For the
longest operation and best performance, we recommend
alkaline batteries, available at your local RadioShack
store.

You can use either the supplied non-rechargeable black
battery holder, or the supplied rechargeable yellow battery
holder. If you use the rechargeable battery holder,
we recommend RadioShack nickel-cadmium or nickel-metal
hydride batteries.

Page 10

Warning: Never install non-rechargeable batteries in the
rechargeable yellow battery holder. Non-rechargeable
batteries can get hot or explode if you try to recharge
them.

Note: You must charge rechargeable batteries before
you use them the first time. See Charging Rechargeable
Batteries on Page 13.
Follow these steps to install the batteries.

1. Press down on the battery compartment cover on the
bottom of the scanner and slide the cover in the
direction of the arrow to remove it.

2. Pull out and slide the battery holder out of the battery
compartment.


Picture missing

Page 11


3. Insert six AA batteries in the battery holder as indicated
by the polarity symbols (+ and -) marked on
the holder.


Picture missing

Cautions:

 Use only fresh batteries of the required size and
recommended type.
 Always remove old or weak batteries. Batteries
can leak chemicals that destroy electronic circuits.
 Do not mix old and new batteries, different types
of batteries (alkaline or rechargeable), or
rechargeable batteries of different capacities.

4. Slide the battery holder into the compartment.


Picture missing

Caution: The battery holder fits only one way. Do
not force it.
5. Replace the cover.

Page 12

When battery power is low, Low Battery! appears
and the scanner beeps continuously. When battery power
is depleted, the scanner turns itself off. Replace all six
non-rechargeable batteries, or recharge the rechargeable
batteries. See Charging Rechargeable Batteries.

Warning: Always dispose of old batteries promptly and
properly. Do not bury or burn them.

Caution: If you do not plan to use the scanner with batteries
for a month or longer, remove the batteries. Batteries
can leak chemicals that can destroy electronic parts.

Charging Rechargeable Batteries
Your scanner has a built-in charging circuit that lets you
charge rechargeable batteries (not supplied) while it is in
the scanner. To charge rechargeable batteries connect
an appropriate AC or DC adapter to the PWR DC 9V jack.
We recommend RadioShack rechargeable batteries.

Note: To charge batteries with a DC adapter from a DC
power source, you must use RadioShack Cat. No. 273-
1825 and a size H Adaptaplug ® (neither supplied) available
at your local RadioShack store. Make sure the
adapter’s voltage is set to 10V.

It takes between 14-16 hours to recharge rechargeable
batteries that are fully discharged. You can operate the
scanner while recharging the rechargeable batteries, but
charging takes longer.

Notes:


 The scanner can charge Ni-MH batteries, however,
these batteries require more than 24-hours to
charge. We recommend using an external quick
charger for Ni-MH batteries.
 Additional charging time is required for high-capacity
rechargeable batteries.

Page 13


Rechargeable batteries last longer and deliver more
power if you let them fully discharge once a month.
To do this, use the scanner until Low Battery!
appears on the display. Then fully charge the
rechargeable batteries.

Important: This scanner can use nickel-cadmium
rechargeable batteries. At the
end of a nickel-cadmium battery's useful
life, it must be recycled or disposed of
properly. Contact your local, county, or
state hazardous waste management authorities
for information on recycling or
disposal programs in your area or call 1-800-843-7422.
Some options that might be available are: municipal curb-side
collection, drop-off boxes at retailers such as your local
RadioShack store, recycling collection centers, and
mail-back programs.


Using AC Power
You can power the scanner using an 9V, 300 mA AC
adapter and a size H Adaptaplug (neither supplied). We
recommend RadioShack Cat. No. 273-1767 (available at
your local RadioShack store).

Cautions:
You must use a Class 2 power source that
supplies 9V DC and delivers at least 300
mA. Its center tip must be set to negative
and its plug must fit the scanner's PWR DC 9V jack.
Using an adapter that does not meet these specifications
could damage the scanner or the adapter.


Always connect the AC adapter to the scanner
before you connect it to AC power. When you finish,
disconnect the adapter from AC power before you
disconnect it from the scanner.

Follow these steps to connect the adapter.

1. Connect the Adaptaplug to the adapter’s cord with
the tip set to negative.

Page 14


2. Plug the adapter’s barrel plug into the scanner’s
PWR DC 9V jack.
3. Plug the adapter into a standard AC outlet.


Picture missing

Using Vehicle Power
You can power the scanner from a vehicle’s 12V power
source (such as a cigarette-lighter socket) using a 9V,
300 mA DC adapter and a size H Adaptaplug (neither
supplied). We recommend RadioShack Cat. No. 273-
1810 (available at your local RadioShack store).

Note: For charging batteries with an optional DC adapter
from a DC power source, use RadioShack Cat. No. 273-
1825 and a size H Adaptaplug (available at your local RadioShack
store). Make sure the adapter’s voltage is set to
10V.
Cautions:
You must use a power source that supplies
9V DC and delivers at least 300 mA. Its
center tip must be set to negative and its
plug must fit the scanner's PWR DC 9V jack. Using an
adapter that does not meet these specifications
could damage the scanner or the adapter.


 Always connect the DC adapter to the scanner
before you connect it to the power source. When you
finish, disconnect the adapter from the power source
before you disconnect it from the scanner.



Follow these steps to connect the adapter.

1. Connect the Adaptaplug to the adapter’s cord with
the tip set to negative.

2. Plug the adapter’s barrel plug into the scanner’s
PWR DC 9V jack.


Page 15


3. Plug the adapter’s cigarette-lighter plug into your
vehicle’s cigarette-lighter socket.

Picture missing

Note: If the scanner does not operate properly when you
connect a DC adapter, unplug the DC adapter from the
cigarette-lighter socket and clean the socket to remove
ashes and other debris.

CONNECTING THE ANTENNA
Follow these steps to attach the supplied flexible antenna
to the ANT jack on the top of your scanner.

Picture missing

1. Align the slots around the antenna’s connector with
the tabs on the ANT jack.

2. Press the antenna down over the jack and turn the
antenna’s base clockwise until it locks into place.

Page 16


Connecting an Optional Antenna
The antenna connector on your scanner makes it easy to
use the scanner with a variety of antennas, such as an
external mobile antenna or outdoor base station antenna.
Your local RadioShack store sells a variety of antennas.
Always use 50-ohm coaxial cable, such as RG-58 or RG-8,
to connect an outdoor antenna. For lengths over 50
feet, use RG-8 low-loss dielectric coaxial cable. If your
antenna’s cable does not have a BNC connector, you will
also need a BNC adapter (also available at your local RadioShack
store).

Follow the installation instructions supplied with the antenna,
route the antenna cable to the scanner, then connect
it to the ANT jack.

Warning: Use extreme caution when installing or removing
an outdoor antenna. If the antenna starts to fall, let it
go! It could contact overhead power lines. If the antenna
touches a power line, contact with the antenna, mast, cable
or guy wires can cause electrocution and death! Call
the power company to remove the antenna. Do not attempt
to do so yourself.

CONNECTING AN EARPHONE/HEADPHONES
For private listening, you can plug an earphone or mono/
stereo headphones (not supplied), available at your local
RadioShack store, into the jack on top of your scanner.
This automatically disconnects the internal speaker.

Picture missing

Page 17


Listening Safely
To protect your hearing, follow these guidelines when you
use an earphone or headphones:

 Do not listen at extremely high volume levels.
Extended high-volume listening can lead to perma-nent
hearing loss.
 Set the volume to the lowest setting before you begin
listening. After you begin listening, adjust the volume
to a comfortable level.
 Once you set the volume, do not increase it. Over
time, your ears adapt to the volume level, so a vol-ume
level that does not cause discomfort might still
damage your hearing.

Traffic Safety
Do not wear an earphone or headphones while you drive
a vehicle or ride a bicycle. This can create a traffic hazard
and can be illegal in some areas.

Even though some earphones and headphones let you
hear some outside sounds when you listen at normal levels,
they still can present a traffic hazard.

CONNECTING AN EXTENSION SPEAKER
In a noisy area, an amplified speaker (not supplied),
available at your local RadioShack store, might provide
more comfortable listening. Plug the speaker cable’s 1 /8-inch
(3.5-mm) mini-plug into your scanner’s headphone jack.

Picture missing

Page 18

USING THE BELT CLIP
You can use the belt clip attached to the back of the
scanner for hands-free carrying when you are on the go.
Slide the belt clip over your belt or waistband.

CONNECTING THE CLONE CABLE
You can transfer the programmed data to and from an-other
PRO-92 using the supplied clone cable. Connect
the cable between each scanner’s PC/IF jacks. See
Cloning the Programmed Data from Scanner to Scanner
on Page 56. You can also upload or download the
programmed data to or from a PC using an optional PC
interface kit available by special order from your local RadioShack
store.

Page 19


ABOUT YOUR SCANNER
Once you understand a few simple terms used in this
manual and familiarize yourself with your scanner’s features,
you can put the scanner to work for you. You simply
determine the type of communications you want to
receive, then set the scanner to scan them.

A frequency is the receiving signal location (expressed in
kHz or MHz). To find active frequencies, you can use the
search function.

You can also search the SEARCH banks, which are preprogrammed
frequencies in the scanner’s memory (see Searching a Preprogrammed Frequency Range on
Page 41 for the frequency list). You can change the
SEARCH frequency ranges.

When you find a frequency, you can store it into a programmable
memory location called a channel, which is
grouped with your other channels in a channel-storage
bank. You can then scan the channel-storage banks to
see if there is activity on the frequencies stored there.
Each time the scanner finds an active frequency, it stays
on that channel until the transmission ends. See Trunk-ing
Operation on Page 57 for terms related to trunking
systems.

UNDERSTANDING BANKS
Channel Storage Banks

To make it easier to identify and select the channels you
want to listen to, channels are divided into 10 banks (0-9)
of 50 (00 to 49) channels each. Use each channel-storage
bank to group frequencies, such as those used by
the police department, fire department, ambulance services,
or aircraft (see Guide to the Action Bands on
Page 67). For example, the police department might use
four frequencies, one for each side of town. You could
program the police frequencies starting with 000 (the 1st
channel in bank 0) and program the fire department fre-quencies
starting with 100 (the 1st channel in bank 1).
The 1st digit identifies the bank (0-9). The 2nd and 3rd
digits identify the channel within the bank (00-49).
Search Banks
This scanner is able to search 10 search banks. You can
also replace a bank with one of the 60 pre-programmed
service bands. (For the default setting, see Searching a
Preprogrammed Frequency Range on Page 41).

The following list shows the 60 pre-programmed service
bands


Please click here to view the Scanner Search Tables





UNDERSTANDING YOUR PRO-92’S MODES
You can program each channel with any of seven receive
modes. Each mode affects how your scanner operates
when scanning and receiving transmissions, and also affects
what transmissions you receive when you set the
scanner to the Closed mode (see Open and Closed
Modes on Page 63). The following sections describe
each mode and how they affect your scanners operation.
See Changing the Receive Mode on Page 53.

PL, DPL and trunking systems all use some form of
coded squelch. Coded squelch techniques involve the transmission
of a special code signal along with the audio of
a radio transmission. A receiver with coded squelch only
activates when the received signal has the correct code.
This lets many users share a single frequency, and de-creases
interference caused by distant transmitters on
the same channel.

In all major metropolitan areas of the United States, every
available radio channel is assigned to more than one user.
Public safety radio systems on the same frequency
are usually set up at a distance of forty miles apart, or
more. This means that you may hear transmissions from
a distant system when your local system is not transmitting.
By entering the PL for a local system, and operating
the bank in closed mode, the scanner will not stop on
transmissions from the distant system.


Page 28


With few exceptions, such as the VHF Aircraft and Marine
bands, almost every other VHF or UHF radio system
uses some form of coded squelch. By far, PL is the most
popular mode among non-trunked systems. For most
scanning use, try setting PL mode for all non-trunked
channels. If you operate the bank in open mode, the
scanner will display the appropriate code.

AM Mode
This sets the scanner to receive transmissions using amplitude
modulation (AM). AM is used for aircraft, military,
some amateur radio, and some government transmissions.
When the scanner receives a transmission on a
channel set to the AM mode, it always stops on the transmission.

FM Mode
This sets the scanner to receive transmissions using frequency
modulation (FM). FM is used for most public safety
transmissions, as well as broadcast, business, and
amateur radio transmissions. When the scanner receives
a transmission on a channel set to the FM mode, it always
stops on the transmission.

CODED SQUELCH MODES
(PL, DPL, AND TRUNKING)
PL Mode
This sets the scanner to decode subaudible tones that
are transmitted with many FM transmissions. Radio system
users use these tones to allow multiple users to
share a single frequency and to prevent interference from
other systems operating nearby on the same frequency.
When you select the PL mode for a channel, you can also
set a specific PL tone for that channel.


page 29

When the scanner receives a transmission on a channel
set to the PL mode, it first decodes the PL tone included
with the transmission. In the Open mode, the scanner
stops on the transmission and displays the PL tone on
the bottom line of the display (or displays None if no tone
is included). In the Closed mode, the scanner only stops
on the transmission if the PL tone matches the tone that
you specified for the channel.

PL tones range in frequency from 67 Hz to 254.1 Hz. You
select a PL tone by pressing STEP while programming a
channel.


DPL Mode
This sets the scanner to decode digital PL tones used
with some FM transmissions. Similar to PL, DPL is a digital
signature encoded on a subaudible carrier. In addition
to preventing interference from other nearby radio
systems, DPL can also identify a specific user or group of
users on a radio system. When you select the DPL mode
for a channel, you can also set a specific DPL code for
that channel.

When the scanner receives a transmission on a channel
set to the DPL mode, it first decodes the DPL code included
with the transmission. In the Open mode, the
scanner stops on the transmission and displays the DPL
code on the bottom line of the display (or displays None if
no code is included). In the Closed mode, the scanner
only stops on the transmission if the DPL code matches
the code that you specified for the channel.

DPL codes range from D017 to D754 (only 100 codes are
actually used within this range). You select a DPL code
by pressing STEP while programming a channel.

DPL is not as popular as PL, because the effective range
of DPL-encoded signals is less than PL.


Page 30


LTR (E. F. Johnson) Mode
This sets the scanner to decode the talk group ID’s used
with an LTR system. This is a trunking system used primarily
by business or private communications service
providers, such as taxi cabs, delivery trucks, and repair
services. LTR systems encode all trunking information as
digital subaudible data that accompanies each transmission.
Users on an LTR system are assigned to specific
talk groups, which are identified by the radio as a six-digit
number. The number is in the form:

AHHUUU

Where:

A = Area code (0 or 1)

H = Home repeater (01 through 20)

U = User ID (000 through 254)

When the scanner receives a transmission on a channel
set to the LTR mode, it first decodes the LTR data included
with the transmission. In the Open mode, the scanner
stops on the transmission and displays the talk group ID
on the bottom line of the display. In the Closed mode, the
scanner only stops on the transmission if the LTR data
matches a talk group ID that you have stored in the
bank’s talk group ID list and have not locked out.

LTR systems are frequently programmed so that each radio
has a unique ID code.

Page 31


Motorola Mode
This sets the scanner to decode the talk group ID’s used
with Motorola trunking systems. These systems are used
by business and public safety groups to efficiently allocate
a small number of frequencies (as few as 5) to many
groups of users (as many as several thousand). To do
this, each group of users in the system is assigned to a
specific talk group. For example, the east side patrol officers
might all be assigned to talk group 2160. One channel
in the system is continuously transmitting data that
identifies which talk groups are active on which channel.

In addition, this talk group information is also transmitted
as subaudible data on each active channel.

When the scanner receives a transmission on a channel
set to the Motorola mode, it first decodes the talk group
ID data included with the transmission. In the Open
mode, the scanner stops on the transmission and dis-plays
the talk group ID on the bottom line of the display.
In the Closed mode, the scanner only stops on the trans-mission
if the talk group ID matches a talk group ID that
you have stored in the bank’s talk group ID list and have
not locked out.

Motorola trunking systems come in three flavors: Type I,
Type II, and Type I/II Hybrids. Each type displays and
uses talk group ID’s in slightly different ways.

Motorola Type I ID’s are in the form FFF-SS, where:

FFF= Fleet ID

SS= Subfleet ID

Type I systems are usually organized with different user
groups assigned to different fleets. For example, all po-lice
users might be grouped under fleet 000. Then, within
each fleet, subfleet ID’s are assigned to subgroups of the
main user group.


Page 32


For example, Police - East Patrol might be assigned to
group 12, making the full Fleet, Subfleet ID be 000-12. To
properly map the raw Type I data to the correct fleet-subfleet
format, you must program the correct fleet map into
the scanner. Fleet map information is widely available on
the internet for most Type I systems in use.

Type II systems talk groups are identified by a 5-digit
number. Valid talk group IDs are divisible by 16. If you try
to enter an invalid talk group ID, the scanner rounds the
ID down to the next valid ID.

Type I/II hybrid systems use both fleet-subfleet and 5-dig-it
formats for talk group ID’s.

Note: Since the subaudible data is included with every
transmission, you can generally receive Motorola sys-tems
from further away than when using systems that
only decode the data channel (like the EDACS mode).
However, as the signal quality worsens, or if the signal is
subject to interference, the scanner might not be able to
reliably decode the talk group ID. In this case, you might
occasionally notice that the talk group ID changes during
a transmission.


EDACS Mode
This sets the scanner to decode the talk group ID’s used
with an EDACS (GE/Ericsson) system. This is a trunking
system used primarily by business or private communications
service providers, as well as by some public safety
organizations. EDACS systems transmit active talk group
information only on a dedicated control channel.

EDACS frequencies are organized in a specific order.
Each frequency is assigned a Logical Channel Number
(LCN). For the PRO-92 to correctly switch to an active
frequency, you must program the frequencies in LCN order,
starting with Memory 01. EDACS talk group ID’s are
entered as a 4-digit decimal number from 0000 to 4096.


Page 33


When there is activity on an EDACS system, that information
is sent out on the control channel. The scanner
decodes the ID for the active talk group. In the Open
mode, the scanner then goes to the transmission and displays
the talk group ID on the bottom line of the display.
In the Closed mode, the scanner only goes to transmissions
that have ID’s that match a talk group ID that you
have stored in the bank’s talk group ID list and have not
locked out.

Because EDACS scanning requires you to have clear reception
of the control channel at all times, EDACS systems
tend to have a smaller usable area. An external
antenna can greatly improve EDACS scanning in a fringe
area. If you are having trouble scanning an EDACS system,
try manually selecting the data channel. If you are
getting good reception, the scanner will indicate talk
group CTR-01. Try changing your location or using an
outdoor antenna to improve reception.

LISTENING TO THE WEATHER
BAND
The FCC (Federal Communications Commission) has allocated
channels for use by the National Oceanic and Atmospheric
Administration (NOAA). Regulatory agencies
in other countries have also allocated channels for use by
their weather reporting authorities.

NOAA and your local weather reporting authority broadcast
your local forecast and regional weather information
on one or more of these channels.

Listening to a Weather Channel
To hear your local forecast and regional weather information,
press WX. Your scanner scans through the weather
band. Your scanner stops within a few seconds on your
local weather broadcast.

Page 46


Weather Alert Feature
This scanner can detect both the weather alert tone and
can decode the digital SAME message that precedes
each alert. If you are monitoring a weather channel when
an alert is broadcast, the scanner sounds an alert and
displays the type of alert being broadcast.

The weather service precedes each weather alert with a
digitally-encoded SAME signal, then a 1050 Hz tone. The
PRO-92 responds to each signal. You can receive weather
alerts any of three ways.


 Press WX to listen to the weather channel.

Note: The scanner only responds to the SAME signal

Notes:


 The scanner responds to either the SAME mode
or 1050 Hz tone in this mode.
 In the WX STANDBY mode, the scanner remains
muted until it receives an alert on the current
weather channel.

When it decodes SAME, it displays the specific type of
weather event (or Tune to TV or Radio) if it does not
recognize the event code. When it detects the 1050 Hz
tone, it displays Weather Alert? In either case, the
scanner also sounds an alert tone.

SPECIAL FEATURES

USING THE DELAY FUNCTION
Note: The delay function turns on automatically when
you turn on the scanner.

Many conversations might have a pause of several seconds
between a query and a reply. To avoid missing a reply,
you can program a 2-second delay into any of your
scanner’s channels. Then, when the scanner stops on
the channel, D appears on the display and the scanner
continues to monitor the channel for 2 seconds after the
transmission stops before it resumes scanning or searching.
You can program a 2-second delay in any of three ways.


 If the scanner is scanning and stops on an active
channel, quickly press FUNC then press DELAY
before it starts to scan again.
If the desired channel is not selected, manually
select the channel then press FUNC then press
DELAY.
 If the scanner is searching and also stopped or
paused, press FUNC then press DELAY to set a delay
in a search bank.

PRIORITY
With the priority feature, you can scan through programmed
channels and still not miss an important or interesting
call on a specific channel. When a channel is
selected as the priority channel and priority is turned on,
the scanner checks that channel every 2 seconds, and
stays on the channel if there is activity until the activity
stops.

The scanner is preset to select Channel 00 in Bank 8 as
the priority channel. You can program a different channel
as the priority channel. Also, you can program a weather
channel as the priority channel.

Notes:


The priority feature does not operate while the scan-ner
receives trunking frequencies.
If you program a WX channel as the priority channel,
the scanner stays in the priority channel only when
the scanner detects the weather alert tone.

Follow these steps to program a channel as the priority
channel.

1. Press MANUAL.

2. Use the number keys to enter the channel number
you want to program as the priority channel. Then
press MANUAL again.

CHANGING THE RECEIVE MODE
The scanner is preset to the most common AM or FM receive
mode for each frequency range. The preset mode
is correct in most cases. However, some amateur radio
transmissions and trunked systems do not operate in the
preset mode. If you try to listen to a transmission when
the scanner is not set to the correct receive mode, the
transmission might sound weak or distorted.
If you want to listen to and watch the private line or trunking
transmission in the closed mode, you need to change
the receive mode. (PL, DPL, MOT, LTR, and ED all use
FM).

Page 56


TRUNKING OPERATION
The PRO-92 scanner tracks transmissions that use the
Motorola ® Type I and Type II (such as Smartnet and Privacy
Plus) and hybrid analog trunking systems, plus GE-
Ericsson (EDACS) and EF Johnson (LTR) type systems,
which are extensively used in many communication sys-tems.
Trunking systems allocate a few frequencies to many different
users. When the mobile unit transmits a signal, one
frequency is chosen from among the allocated frequencies
in that trunking system. The user’s ID talk group is
sent with the signal.

Trunking group frequencies are included in the supplied
Police Call Trunking Guide. Frequency fleet map and talk
group information is also widely available on the Internet,
including at www.trunkscanner.com.

UNDERSTANDING TRUNKING
In the past, groups that transmit frequently, such as police
departments, were restricted to transmitting on just a
few frequencies. This resulted in heavy traffic and often
required 2-way radio users to wait for a specific frequency
to clear before transmitting.

Trunked systems allow more groups of 2-way radio users
to use fewer frequencies. Instead of selecting a specific
frequency to transmit on, a trunked system chooses one
of several frequencies when the 2-way radio user presses
PTT (push to talk). The system automatically transmits
the call on that frequency, and also sends a code that
identifies that 2-way radio user’s transmission on a control
channel.

This scanner lets you easily hear both the call and response
transmissions for that 2-way radio user and therefore
follow the conversation. For Motorola and LTR
systems, the scanner uses the subaudible data sent with
each transmission to identify talk groups. For EDACS, the
scanner monitors the control channel between each transmission
to identify talk groups.


Page 57



PROGRAMMING TRUNKING
FREQUENCIES
Program trunking frequencies just as you program normal,
non-trunked frequencies, but store the appropriate
mode (MO, ED, or LT) with each frequency.

Notes:


 EDACs systems must be stored in banks by them-selves.
You can, however, mix Motorola, or LTR and
conventional channels in a bank.
 During Trunking operation, lock out all data chan-nels.
(See Locking Out Channels or Frequencies on Page 48.)

1. Press PGM and select the bank, then press TRUNK to
enter the ID program mode.

2. Press MODE to select LT for EF Johnson, MO for
Motorola or ED for EDACS (GE-Ericsson) system to
scan. This sets the talk group ID decoding method to
be used for the bank.

Note: If you programmed a Motorola Type I or
Hybrid system, see Programming Fleet Maps.


PROGRAMMING FLEET MAPS
If you want to receive a Motorola Type I system, you
need to set the fleet map.

Fleet maps are included along with other information
about Motorola Type I systems on the Internet. To program
the fleet map:

1. Press PGM.

2. Press TRUNK.

Birdie Frequencies
Every scanner has birdie frequencies. Birdies are signals
created inside the scanner’s receiver. These operating
frequencies might interfere with transmissions on the
same frequencies. If you program one of these frequen-cies,
you hear only noise on that frequency. If the interfer-ence
is not severe, you might be able to turn SQUELCH
clockwise to cut out the birdie.

To find the birdies in your scanner, begin by disconnect-ing
the antenna and moving it away from the scanner.
Make sure that no other nearby radio or TV sets are
turned on near the scanner. Use the search function and
scan every frequency range from its lowest frequency to
the highest. Occasionally, the searching will stop as if it
had found a signal, often without any sound. This is a
birdie. Make a list of all the birdies in you scanner for fu-ture
reference.

FREQUENCY CONVERSION
The tuning location of a station can be expressed in frequency
(kHz or MHz) or in wavelength (meters). The following
information can help you make the necessary
conversions.

1 MHz (million) = 1,000 kHz (thousand)

To convert MHz to kHz, multiply the number of megahertz
by 1,000:

30.62 (MHz) X 1000 = 30,620 kHz

To convert from kHz to MHz, divide the number of kilohertz
by 1,000:

127,800 (kHz) / 1000 = 127.8 MHz

To convert MHz to meters, divide 300 by the number of
megahertz:

300 / 50 MHz = 6 meters

RESETTING/INITIALIZING THE
SCANNER
If the scanner’s display locks up or does not work proper-ly
after you connect a power source, you might need to
reset or initialize it.

Important: If you have problems with the scanner, first
try to reset it to retain all memory. If that does not work,
you can initialize the scanner; however, initializing clears
all information stored in the scanner’s memory.

Resetting the Scanner
1. Turn off the scanner, then turn it on again.

2. Insert a pointed object, such as a straightened paper
clip, into the reset opening on the side of the scanner.
Then gently press and release the reset button
inside the opening and the backlight lights.




Note: Pressing RESET does not clear the scanner’s
memory.

Initializing the Scanner

Important: This procedure clears all information you
stored in the scanners memory. Initialize the scanner
only when you are sure the scanner is not working properly.

1. Turn off the scanner, then turn it on again. Welcome
To Multi-System Trunking appears on the display.


Page 75


2. Press 0 then 1 while the display shows Welcome
To Multi-System Trunking. Initializing
Please Wait. appears on the display about
25 seconds.

Note: Do not turn off the scanner until the initialization
is complete and Welcome To Multi-System Trunking appears again.

CARE AND MAINTENANCE
Your RadioShack PRO-92 500-Channel Portable Trunking
Scanner is an example of superior design and craftsmanship.
The following suggestions will help you care for
your scanner so you can enjoy it for years.

Keep the scanner dry. If it gets wet, wipe it
dry immediately. Liquids can contain minerals
that can corrode the electronic circuits.

Use only batteries of the recommended
size and type. Always remove old and weak
batteries. They can leak chemicals that de-stroy
electronic circuits.

Handle the scanner gently and carefully.
Dropping it can damage circuit boards and
cases and can cause the scanner to work
improperly.

Use and store the scanner only in normal
temperature environments. Temperature
extremes can shorten the life of electronic
devices, damage batteries, and distort or
melt plastic parts.

Keep the scanner away from dust and dirt,
which can cause premature wear of parts.
Wipe the scanner with a damp cloth occasionally
to keep it looking new. Do not use
harsh chemicals, cleaning solvents, or
strong detergents to clean the scanner.

Modifying or tampering with the scanner’s internal com-ponents
can cause a malfunction, invalidate your scanner’s
warranty and void your FCC authorization to
operate it. If your scanner is not operating as it should,
take it to your local RadioShack store for assistance.
