INTRODUCTION
Your new RadioShack 500-Channel
Mobile Trunk-Tracking Scanner is one
of a new generation of scanners designed to track Motorola Type I,
Type II (such as Smartnet and Privacy Plus), GE/Ericsson EDACS, E.F.
Johnson LTR, and hybrid analog
trunking systems, which are extensively used in many 800 MHz, 900
MHz and UHF 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 group of frequencies. Instead of selecting a specific frequency for a transmission, the
2-way radio 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 2way radio user’s transmission on a different frequency called a data channel.
Since the trunking system might send
individual 2-way radio user’s calls and
response transmissions on different
frequencies, it is difficult to listen to
trunked communications using a regular scanner. The scanner monitors the
data channel frequency sent with a 2way radio user’s transmission and instantly switches to an active frequency, so you can hear the call and
response for that 2-way radio user
and 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, and amateur radio services, and you can
change your selection at any time.
FEATURES
Your scanner also has these special
features:
Ten Channel-Storage Banks — let
you store 50 channels in each bank
(500 total channels), letting you group
channels so you can more easily identify calls.
Flexible Operation — you can track
Motorola, GE/Ericsson, and E.F.
Johnson LTR trunking systems (used
by most trunking communications systems), letting you hear more calls than
many standard trunking scanners.

Simultaneous Trunking Operation
— you can scan all 3 types of trunking
systems, and both trunking and conventional frequencies, at the same
time.
Text Input — you can manually enter
the name of the service you are listening to so the service name appears
when you scan it, making it easier to
identify transmissions.
Digital Weather Alert — displays the
weather event text so you can see the
reason for the alert.
Note: The scanner does not display
the actual location referenced by
SAME messages. It uses only the
message portion of the SAME signal.
Ten 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.
Private/Digital Private Line Receiving — decodes and displays the Continuous Tone Coded Squelch System
(CTCSS) and Digital Coded Squelch
(DCS) tone signal being transmitted,
letting you see if the transmitter provides these services.
12-Character, 4-Line, Dot-Matrix
Display — makes it easy to view and
change displayed information.
Frequency Coverage to 960 MHz —
provides a wide range of frequencies
you can listen to.
Clone/Remote PC Function — lets
you transfer programmed data directly
to another Cat. No. 20-196 or Cat. No.
20-522 scanner. You can also upload
or download the programmed data to
or from a PC using an optional interface kit.
Triple-Conversion Circuitry — virtually eliminates any interference from
IF (intermediate frequency) images,
so you hear only the selected frequency.
Scan Delay — delays scanning for
about 2 seconds before moving to another channel, so you can hear more
replies that are made on the same
channel.
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.
Priority Channel — lets you program
one channel as the priority channel.
As the scanner scans it checks the priority channel every 2 seconds so you
don't miss transmissions on that channel.
ATT (Attenuate) Button — lets you
program each memory location to reduce the scanner’s sensitivity to
strong local signals, to reduce interference or noise caused by these signals.

let you set the scanner to search at up
to 50 steps per second and scan at up
to 25 channels per second, to help
you quickly find interesting transmissions.

PREPARATION
CONNECTING AN
ANTENNA
You must install an antenna before
you can operate the scanner. Your local RadioShack store sells a variety of
scanner antennas for both mobile and
base-station use. Choose the one that
best meets your needs.
When deciding on a mobile or basestation antenna and its location, consider these points.
• The antenna should be as high as
possible on a vehicle or a house.
• The antenna and its cable should
be as far as possible from sources
of electrical noise (ignition systems, gauges, and so on).
• The antenna should be vertical for
the best performance.
MOUNTING AN
ANTENNA
Once you choose an antenna, follow
the mounting instructions supplied
with the antenna. Then route the antenna cable to the scanner.
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.
Always use 50-ohm coaxial cable,
such as RG-58 or RG-8, to connect an
8
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 (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 you install or remove 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.
MOUNTING THE
SCANNER IN YOUR
VEHICLE
Before you mount the scanner, make
sure you have all the necessary materials. Then confirm that the scanner
fits your vehicle’s mounting area. This
scanner is a DIN-E size unit that requires a 2-inch high by 611/16-inch wide
by 51/2-inch deep (50 × 170 × 140 mm)
mounting area.
20-196a.fm Page 9 Friday, June 2, 2000 3:48 PM
Caution: Be sure to avoid obstructions behind the mounting surface.
6. Connect the antenna’s cable to
the ANT jack on the back of the
scanner.
Follow these steps to mount the scanner in your vehicle.
1. Choose a mounting location, then
use the supplied mounting bracket
as a template to mark the positions for the mounting screw
holes.
2. In the marked positions, drill holes
slightly smaller than the supplied
screws.
3. Attach the mounting bracket to the
mounting location using the supplied screws and lock washers.
Note: If the antenna cable’s connector
does not fit in the ANT jack, you might
also need a Motorola-to-BNC antenna
plug adapter (available at your local
RadioShack store).
POWERING THE
SCANNER
4. Attach a rubber washer to both of
the mounting bracket’s holes.
5. Attach the scanner to the mounting bracket using the supplied
mounting knobs.
You can power your scanner using either the supplied DC power cord or
from your vehicle’s cigarette lighter
socket using an optional DC cigarette
lighter power cable.
Cautions:
You must use a power
source that supplies 12V
DC and delivers at least
500 mA. Its center tip must be set
to positive and its plug must fit the
scanner's DC 13.8V jack. The supplied DC power cord meets these
specifications. Using a power cord
that does not meet these specifications could damage the scanner
or the adapter.
!
9
20-196a.fm Page 10 Friday, June 2, 2000 3:48 PM
• Always connect the adapter or DC
power cord to the scanner before
you connect it to the power
source. When you finish, disconnect the adapter or DC power
cord from the power source before
you disconnect it from the scanner.
• For added safety and to protect
your scanner, disconnect the
cable from your vehicle battery’s
negative (–) terminal before you
begin.
Follow these steps to connect the supplied DC power cord.
1. Connect the power cord’s black
wire to a chassis ground, such as
a metal screw attached to a metal
part of the vehicle’s frame. Be
sure that the screw is not insulated from the frame by a plastic
part.
2. Connect the power cord’s red wire
(with in-line fuse) to a source of
voltage that turns on and off with
the ignition switch, such as a
spare accessory terminal in your
vehicle’s fuse box.
3. Insert the power cord’s barrel plug
into the DC 13.8V jack on the back
of the scanner.
4. Reconnect the cable to the vehicle battery’s negative (–) terminal.
To power the scanner from a vehicle’s
12V power source (such as a cigarette-lighter socket), you need a 12V,
500-mA DC cigarette-lighter adapter
(not supplied), available at your local
RadioShack store.
To connect an optional DC cigarettelighter power cable, insert its barrel
plug into the DC 13.8V jack on the back
of the scanner, then plug the power
cable into your vehicle’s cigarette
lighter socket.
Note: If you use a cigarette-lighter
power cable and your vehicle’s engine
is running, you might hear electrical
noise from the engine while scanning.
This is normal.
USING THE SCANNER
AS A BASE STATION
You can place this scanner on a desk,
shelf, or table to use it as a base station.
10
20-196a.fm Page 11 Friday, June 2, 2000 3:48 PM
Using Standard AC Power
To power the scanner from an AC outlet, you need an AC adapter (not supplied) with a 5.5 mm outer diameter/
2.1 mm inner diameter tip.
3. Plug the adapter into a standard
AC outlet.
12V
Cautions:
You must use a Class 2
power source that supplies 12V DC and delivers at least 500 mA. Its center tip
must be set to positive and its
plug must fit the scanner's DC
13.8V 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.
CONNECTING AN
EXTENSION SPEAKER
In a noisy area, an amplified extension
speaker (available at your local RadioShack store) positioned in the right
place might provide more comfortable
listening.
Plug the speaker cable’s 1/8-inch (3.5mm) plug into your scanner’s EXT SP
jack.
1. Connect the adapter's 5.5 mm
outer diameter/2.1 mm inner
diameter tip to the adapter's cord
and set the barrel plug's tip to positive.
2. Insert the adapter's barrel plug
into the DC 13.8V jack on the back
of the scanner.
Note: Connecting an external speaker
disconnects the scanner’s internal
speaker.
11
20-196a.fm Page 12 Friday, June 2, 2000 3:48 PM
CONNECTING AN
EARPHONE/
HEADPHONES
For private listening, you can connect
an earphone or headphones with a 1/8inch (3.5-mm) plug to the EXT SP jack
on the back of the scanner. (Your local
RadioShack store carries a wide selection of earphones and headphones). This automatically disconnects the internal speaker.
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 highvolume listening can lead to permanent hearing loss.
• Set VOLUME to the lowest setting
before you begin listening. After
you begin listening, adjust VOLUME to a comfortable level.
12
• Once you set VOLUME, do not
increase it. Over time, your ears
adapt to the volume level, so a
volume level that does not cause
discomfort might still damage your
hearing.
CONNECTING THE CLONE
CABLE
You can transfer the programmed
data to and from another Cat. No. 20196 or Cat. No. 20-522 scanner using
the supplied clone cable. Connect the
cable between each scanner’s PC/IF
jacks. See “Cloning Programmed
Data from Scanner to Scanner” on
Page 35. You can also upload or
download the programmed data to or
from a PC using an optional PC interface kit available through your local
RadioShack store.
20-196a.fm Page 13 Friday, June 2, 2000 3:48 PM
UNDERSTANDING 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 tuning location of a station (expressed in kHz or MHz). To find
active frequencies, you can use the search function.
You can also search the service-search banks, which are preset groups of frequencies categorized by type of service.
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.
A LOOK AT THE KEYPAD
Your scanner’s keys might seem confusing at first, but this information should help
you understand each key’s function.
Note: Some of the scanner’s keys perform more than one function and are marked
with more than one label. The steps in this Owner’s Manual show only the label on
the key appropriate to the action being performed.

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 channels (00 to 49) 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 45). 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 frequencies starting with 100
(the 1st channel in bank 1). The first
digit identifies the bank (0–9). The
second and third 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 preprogrammed
service bands. (For the default setting,
see “Searching a Preprogrammed
Frequency Range” on Page 25).
UNDERSTANDING
CTCSS/DCS
Continuous Tone Coded Squelch System (CTCSS) and Digital Coded
Squelch (DCS) are two methods used
to prevent interference by other radio
communications. Your scanner can
receive transmissions that use these
codes.
When your scanner receives a CTCSS transmission, PL (private line) appears. When your scanner receives a
DCS transmission, DPL (digital private
line) and a 3-digit code appear.
PL Codes
PL codes are low-frequency audio
tones that are used to differentiate different users on the same channel. PL
codes appear according to the EIA
standard CTCSS tones, and range
from 67.0 Hz to 254.1 Hz. PL codes
are displayed directly as a frequency.
DPL Codes
DPL codes are similar to PL codes,
except they might be transmitted as
either tones or digital codes. Although
there are as many as 4096 DPL
codes, only about 100 are actually
used.
DPL codes appear in the format
Dxxx, where xxx is an octal code.
18
20-196a.fm Page 19 Friday, June 2, 2000 3:48 PM
UNDERSTANDING YOUR
SCANNER’S MODES
Open and Closed Modes
You can set your scanner to change
the way it receives signals. These settings, called open mode and closed
mode, affect how the scanner receives signals from communications
systems that use some type of closed
squelch (such as PL, DPL, LTR, MOT,
and ED systems). You can set each of
the scanner’s channel storage banks
to open or closed mode.
In open mode, the scanner scans signals transmitted in all systems. In
closed mode, the scanner scans signals transmitted only under the following conditions:
• When the signals are in the FM
mode.
• When the signals are in the LT,
MO, or ED mode and the signal's
ID code matches the programmed
ID code.
• When the signals are in the PL or
DPL mode and the signal's ID
code matches the programmed ID
code.
Note: When the signals are in the
PL or DPL mode, the scanner
receives all signals on a channel
when the ID code is set to NONE.
You can also select the users or talk
groups you want the scanner to receive in closed mode.
When you set a channel storage bank
to open mode, + (open) appears under the bank’s number while scanning.
When you set a channel storage bank
to closed mode, – (closed) appear under the channel storage bank's number while scanning. Or, OPEN or
CLOSED appears while the scanner is
in manual mode or while the scanner
is receiving a signal during scanning.
See “Changing the Open/Closed
Mode” on Page 32 for more information about setting the open and closed
modes.
LTR (E. F. Johnson) Mode
You can set your scanner so it decodes the talk group IDs used with
LTR systems. This setting is called the
LTR mode.
LTR systems are trunking systems
used primarily by business or private
communications service providers,
such as taxicabs, delivery trucks, and
repair services. These 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 six-digit numbers. These numbers are in the form AHHUUU, where:
A = Area code (0 or 1)
H = Home repeater (01 through 20)

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.
Motorola Mode
You can set your scanner so it decodes the talk group IDs used with
Motorola trunking systems. This setting is called the Motorola mode.
Motorola systems are trunking systems used primarily 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
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 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 categories: Type I, Type II, and
Type I/II Hybrid. Each category displays and uses talk group IDs in slightly different ways.
Motorola Type I IDs 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, a valid
fleet/subfleet ID identifying all detectives within a police department might
be 000-12, where 000 identifies all
police users and 12 identifies the Detective division.
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.
20-196a.fm Page 21 Friday, June 2, 2000 3:48 PM
Type II system 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-digit formats for
talk group IDs.
Note: If the scanner decodes control
channel data while receiving transmissions from a Motorola trunking system, CNTRL appears on the bottom
line of the display. For example:
EDACS Mode
You can set your scanner so it decodes the talk group IDs used with
EDACS (GE/Ericsson) trunking systems. This setting is called the
EDACS mode.
EDACS systems are trunking systems
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 scanner to correctly
switch to an active frequency, you
must program the frequencies in LCN
order, starting with Memory 01.
EDACS talk group IDs are entered as
a 4-digit decimal number from 0000 to
4096.
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 IDs 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
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 CTL-01. Try changing your location or using an outdoor
antenna to improve reception.

priority channel even if the bank it
is contained in is set to closed
mode (see “Changing the Open/
Closed Mode”).
CHANGING THE OPEN/
CLOSED MODE
You can set each of the scanner’s
banks to open mode or closed mode.
When a bank is set to open mode, the
scanner receives all transmissions on
the frequencies in that bank. When a
bank is set to closed mode, the scan-
20-196a.fm Page 33 Friday, June 2, 2000 3:48 PM

TRUNKING OPERATION
The 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 systems.
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.
To receive trunking signals, you must
store all the trunking group frequencies in one bank (see “Storing Known
Frequencies into Channels” on
Page 22) and input ID codes in the ID
memory (see “Finding and Storing Active Frequencies” on Page 25). To listen to the transmission, the mode of
the programmed channel must be the
same as that of the trunking channel
(LT, MO, or ED).
When an ID code is received, the ID
list for the bank is searched, and if
found, the text name stored for the ID
appears. If not found, scanning resumes immediately unless the bank is
in open trunking mode.
Note: There might be more than one
talk group transmitting at a time in
some Motorola trunking systems. If
you set the scanner to manually tune
in Motorola trunking mode, you will
hear the talk group on that channel,
but the display will alternate between
all active IDs.
36
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, at
www.trunkscanner.com for example.
UNDERSTANDING
TRUNKING
In the past, groups that transmit frequently, such as police departments,
could transmit on only 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 transmits. 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 EDACS
and Motorola (above 806 MHz range),
the scanner monitors the control channel between each transmission to identify talk groups. For some Motorola
(under 512 MHz range) and LTR systems, the scanner uses the subaudible
data sent with each transmission to
identify talk groups.
20-196a.fm Page 37 Friday, June 2, 2000 3:48 PM
SETTING SQUELCH FOR
THE TRUNKING MODE
Your scanner automatically mutes the
audio during trunk scanning when it
decodes control channel data. However, we recommend you turn SQUELCH
clockwise and leave it set to a point
just after the hissing sound stops. This
lets the scanner quickly acquire the
data channel.
PROGRAMMING
TRUNKING
FREQUENCIES
You program trunking frequencies just
like non-trunked frequencies, except
that you must store the appropriate
mode (MO, ED, or LT) with each frequency.
Notes:
• You can store only one trunked
EDACs and Motorola channel in a
bank. You can, however, mix LTR
and conventional channels in a
bank.
• If you are scanning UHF trunking
frequencies under the 512 MHz
range using subaudible data and
are not using a base frequency
and offset, lock out all data channels. See “Programming Motorola
Trunking Systems (UHF-Lo)” on
Page 38 and “Locking Out Channels, Frequencies, and Trunking
IDs” on Page 30. Turn off the
scanner to remove the lockouts.
• If you are programming trunked
frequencies for Motorola Type I
and hybrid systems, you must first
program the fleet map (see “Programming
Fleet
Maps”
on
Page 39).
• You must store frequencies using
the subaudible trunking method in
banks mode by mode.
Follow these steps to program trunked
frequencies.
1. Press PROG and select the bank,
then press TRUNK to enter the ID
program mode.
2. Repeatedly press MODE to select
LT for EF Johnson, MO for Motorola, or ED for the EDACS (GE/
Ericsson) system to scan. This
sets the talk group ID decoding
method to be used for the bank.
Notes:
• If you select -- instead of LT,
MO, or ED, the scanner does
not scan trunked frequencies.
Instead, you see:
• If you programmed a Motorola
Type I or Hybrid system, see
“Programming Fleet Maps” on
Page 39.
3. Press PROG to enter the program
mode.

www.trunkscanner.com,
Internet sources, or locallypublished guidebooks.
5. Repeatedly press MODE to select
the trunking mode (LT for EF
Johnson, MO for Motorola, or ED
for the EDACS (GE/Ericsson) system).
• The scanner automatically decodes subaudible data it receives
in the VHF band.
6. Press SCAN. If the scanner’s
receive mode matches the ID
mode, T appears and the scanner
scans the frequencies.
Programming Motorola
Trunking Systems (UHF-Lo)
You can program the scanner to receive transmissions in the UHF-Lo
band (380–512 MHz) of the Motorola
Trunking System. You can receive
these transmissions by:
• Checking the trunking system’s
base frequency and offset frequency. You must program the
system’s base frequency and offset frequency to do this.
• Decoding the subaudible data
transmitted with the signals. When
you do this, the scanner might
detect wrong IDs but you can easily receive trunking frequencies
without programming the base
and offset frequencies.
• If you try to enter an offset frequency in the VHF and UHF-Hi
bands (137–174 and 806–960
MHz), the scanner will ignore the
entry.
Follow these steps to program Motorola trunking frequencies in the UHFLo band.
1. Select the bank, then press PROG
to enter the program mode.
2. Store the base frequency into
channel 00 of the bank you
selected, then store the trunking
frequencies
into
subsequent
channels in the same bank (see
“Storing a Frequency to a Specified Channel” on Page 26).
3. Press TRUNK then repeatedly
press MODE to select MO (Motorola).
4. Press FUNC then 9. 12.5 kHz
(the default offset frequency)
appears.
Notes:
• Base and offset frequencies vary
for each type of trunking system.
You can get information about
these frequencies for the trunking
system you want to scan using

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 frequencies, you hear only
noise on that frequency. If the interference is not severe, you might be able to turn
SQUELCH clockwise to cut out the birdie. This scanner’s birdie frequencies (in

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 search 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. That is a birdie. Make a
list of all the birdies in your scanner for future 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) × 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
You might need to reset or initialize
the scanner if:
• the scanner’s display locks up.
• the scanner does not work properly after you connect power.
• the scanner is dropped or subjected to a physical or electrical
shock.
Important: If you have problems, first
try to reset the scanner. If that does
not work, you can initialize the scanner; however, this clears all information stored in your scanner’s memory.
Resetting the Scanner
1. Turn off the scanner, then turn it
on again. Welcome To MultiSystem Trunking appears.
2. Insert a pointed object, such as a
straightened paper clip, into the
reset hole on the back of the
scanner. Then gently press and
release the reset button inside the
opening.
Note: Pressing the reset button does
not clear the scanner’s memory.

CARE AND MAINTENANCE
Your RadioShack 500-Channel Mobile Trunk-Tracking 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
might contain minerals that can corrode the electronic circuits.
Use and store the scanner only in normal temperature environments.
Temperature extremes can shorten the life of electronic devices and
distort or melt plastic parts.
Keep the scanner away from dust and dirt, which can cause premature
wear of parts.
Handle the scanner gently and carefully. Dropping it can damage circuit boards and cases and can cause the scanner to work improperly.
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 components can cause a malfunction and might invalidate its warranty and void your FCC authorization to operate it. If your scanner is not performing as it should, take it to your local
RadioShack store for assistance.
