FEATURES
Your RadioShack Handheld Scanner is one of a new generation of scanners designed to track
Motorola® Type I and II (such as Smartnet® and Privacy Plus®) and hybrid analog trunking systems,
GE-Ericsson (EDACS®) type systems, 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 trunking scanner monitors the data sent
20-527 Owner’s Manual Draft
Page 2 of 60
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.
This scanner gives you direct access to over 65,000 frequencies including those used by police and fire
departments, ambulance services, government agencies, air, and amateur radio services.
Your scanner includes these features:
Simultaneous Trunking Operation – tracks three trunking systems (Motorola, EDACS and LTR) and
conventional systems at the same time.
Automatic Channel Programming – automatically determines the group trunking frequencies, for
Motorola trunking systems only, once the control channels are programmed.
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 during priority operation.
Digital Weather Alert – displays the weather event text with four alert levels so you can see and hear the
reason for the alert.
CTCSS and DCS Subaudible Encoded Squelch Modes – restricts conventional channel reception to
transmissions using specified subaudible CTCSS tone or DCS data code when scanning or parked on a
single chnanel. Code Search feature instantly displays the tone or code in use. Takes advantage of
subaudible squelch tail elimination turn off codes when they are present.
Preprogrammed Frequency Ranges – lets you search for transmissions within preset frequency ranges
or within ranges you set, to reduce search time and select interesting frequencies more quickly.
Hyperscan™ and Hypersearch™ – the scanner scans at up to 60 channels per second and searches up
to 75 frequencies per second, to help you quickly find transmissions.
Signal Stalker – let you set the scanner so it detects then displays the frequency of a nearby strong radio
transmission.
Priority Channel — lets you set the scanner to check one channel every 2 seconds so you do not miss
transmissions.
20-527 Owner’s Manual Draft
Page 3 of 60
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.
Your scanner can receive these frequencies:
• 25 – 54 MHz
• 108 – 136.99166 MHz
• 137 – 174 MHz
• 216.0025 – 225 MHz
• 225.025 – 405.975 MHz
• 406 – 512 MHz
• 806 – 823.9875 MHz
• 849 – 868.9875 MHz
• 894 – 960 MHz
• 1240 – 1300 MHz
Use “A General Guide to Frequencies” on Page 69 to help you target frequency ranges in your service
area so you can search for a wide variety of transmissions.

Scanning Legally
20-527 Owner’s Manual Draft
Page 4 of 60
Your scanner covers frequencies used by many different groups including police and fire departments,
ambulance services, government agencies, private companies, amateur radio services, military
operations, pager services, and wireline (telephone and telegraph) service providers. It is legal to listen to
almost every transmission your scanner can receive. However, there are some transmissions you should
never intentionally listen to. These include:
• Telephone conversations (cellular, cordless, or other private means of telephone signal transmission)
• Pager transmissions
• Any scrambled or encrypted transmissions
According to the Electronic Communications Privacy Act (ECPA), you are subject to fines and possible
imprisonment for intentionally listening to, using, or divulging the contents of such a transmission unless
you have the consent of a party to the communication (unless such activity is otherwise illegal).
This scanner has been designed to prevent reception of illegal transmissions. This is done to comply with
the legal requirement that scanners be manufactured so as to not be easily modifiable to pick up those
transmissions. Do not open your scanner's case to make any modifications that could allow it to pick up
transmissions that are illegal to monitor. Doing so could subject you to legal penalties.
We encourage responsible, legal scanner use.
In some areas, mobile use of this scanner is unlawful or requires a permit. Check the laws in your area.
PREPARATION
Power Sources
You can power your scanner from any of these 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 XX).
• vehicle power (with an optional DC adapter – see “Using Vehicle Battery Power” on Page XX).
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” and “Charging Rechargeable Batteries”
on Page XX.
• If the scanner stops working properly after connecting it to power, try resetting it. See
20-527 Owner’s Manual Draft
Page 5 of 60
“Resetting/Initializing the Scanner” on Page XX.
• You must change rechargeable batteries before you use them the first time. See “Charging
Rechargeable Batteries” on Page XX.
Using Batteries
You can power the scanner with four AA batteries (not supplied). 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 battery holder (black), or the supplied rechargeable
battery holder (yellow). If you use the rechargeable battery holder, we recommend RadioShack
nickel-metal hydride (Ni-MH) batteries.
You must charge rechargeable batteries before you use them the first time. See “Charging Rechargeable
Batteries” on Page XX.
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.
CAUTIONS:
• The battery holder fits only one way. Do not force it.
• 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.
• If you do not plan to use the scanner with batteries for a month of longer, remove the batteries.
Batteries can leak chemicals that can destroy electronic parts.
Follow these steps to install the batteries.
1. Press in on the battery compartment cover on the back of the scanner and slide the cover down to
remove it.
2. Pull the battery holder out of the battery compartment.
3. If you are using non-rechargeable batteries, place them into the black holder, as indicated by the
polarity symbols (+ and -) marked on the holder.
If you are using rechargeable batteries, place them into the yellow holder as indicated by the polarity
symbols (+ and -) marked on the holder.
4. Place the battery holder into the battery compartment.
5. Replace the cover.
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 four non-rechargeable batteries, or recharge
20-527 Owner’s Manual Draft
Page 6 of 60
the rechargeable batteries. See “Charging Rechargeable Batteries” on Page XX.
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 nickel-metal hydride (Ni-MH) or nickel
cadmium (Ni-CD) rechargeable batteries (not supplied) while they are in the scanner. To charge
rechargeable batteries, connect an appropriate AC or DC adapter to the PWR DC 9V jack. For best
results we recommend RadioShack rechargeable nickel-metal hydride (NiMH) 1600 mAh batteries.
IMPORTANT: The EPA certified RBRC© Battery Recycling Seal on the nickel-cadmium (Ni-Cd) battery
indicates RadioShack is voluntarily participating in an industry program to collect and recycle these
batteries at the end of their useful life, when taken out of service in the United States or Canada. The
RBRC program provides a convenient alternative to placing used Ni-Cd batteries into the trash or the
municipal waste stream, which may be illegal in your area. Please call 1-800-THE-SHACK
(1-800-843-7422) for information on Ni-Cd battery recycling and disposal bans/restrictions in your area.
RadioShack’s involvement in this program is part of the company’s commitment to preserving our
environment and conserving our natural resources.
To charge batteries with a DC adapter from a DC power source, you must use a 9V, 300 mA DC adapter
such as RadioShack Cat. No. 273-1810 or 273-1815 and a size C Adaptaplug™ (neither supplied). Both
are available at your local RadioShack store. Make sure the adapter’s voltage is set to 9V.
It takes about 16 hours to recharge fully discharged 1600 mAh NiMH rechargeable batteries. You can
operate the scanner while recharging the rechargeable batteries, but charging takes longer.
Notes:
• The scanner can also charge Ni-Cd batteries. 600 mAh batteries require 6 hours and 850 mAh
batteries require 8 hours to charge.
• When you charge Ni-Cd batteries, do not overcharge them. Overcharging shortens battery life.
• 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. Then fully charge the rechargeable batteries.
Using AC Power
You can power the scanner using a 9V, 300 mA AC adapter and a size C Adaptaplug (neither supplied).
Both are available at your local RadioShack store.
20-527 Owner’s Manual Draft
Page 7 of 60
1. Connect the Adaptaplug to the adapter’s cord with the tip set to positive.
CAUTION
! 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 positive 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.
2. Plug the adapter’s barrel plug into the scanner’s PWR DC 9V jack.
3. Plug the adapter’s two-prong plug into an AC outlet.
Using Vehicle Battery Power
You can power the scanner from a vehicle’s 12V power source (such as cigarette-lighter socket) using a
9V, 300 mA DC adapter and a size C Adaptaplug™ adapter (neither supplied). Both are available at your
local RadioShack store.
CAUTION
! 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 positive 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.
1. Connect the Adaptaplug to the adapter’s cord with the tip set to positive.
2. Plug the adapter’s barrel plug into the scanner’s PWR DC 9V jack.
3. Plug the adapter’s cigarette-lighter plug into your 12V power source.
Note: If the scanner does not operate properly when you connect a DC adapter, unplug the DC adapter
from the power source and clean the socket, or check the adapter’s internal fuse.
Connecting the Antenna
To attach the supplied flexible antenna to the antenna jack on the top of your scanner, align the slots
around the antenna’s connector with the tabs on the antenna jack. Press the antenna down over the jack
and turn the antenna’s base clockwise until it locks into place.
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.
20-527 Owner’s Manual Draft
Page 8 of 60
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 (not supplied, 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 antenna 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, touching 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 1/8-inch (3.5 mm) mini-plug earphone or headphones (not
supplied), available at your local RadioShack store, in the HEADPHONE jack on top of your scanner.
This automatically disconnects the internal speaker.
Listening Safely
To protect your hearing, follow these guidelines when you use headphones.
• Set the volume to zero before putting on the headphones. With the headphones on, adjust the volume
to a comfortable level.
• Avoid increasing the volume once you set it. Over time, your sensitivity to a volume level decreases, so
volume levels that do not cause discomfort might damage your hearing.
• Avoid or limit listening at high volume levels. Prolonged exposure to high volume levels can cause
permanent hearing loss.
Traffic Safety
Wearing headphones while operating a motor vehicle or riding a bicycle can create a traffic hazard and
could be illegal in some areas.
Even though some headphones let you hear some outside sounds when listening at normal volume
levels, they still can present a traffic hazard. Exercise extreme caution!
Connecting an Extension Speaker
In a noisy area, an amplified speaker (not supplied), available at your local RadioShack store, might
20-527 Owner’s Manual Draft
Page 9 of 60
provide more comfortable listening. Plug the speaker cable’s 1/8-inch (3.5 mm) mini-plug into your
scanner’s HEADPHONE jack.
Note: You must use an amplified speaker with this scanner. Non-amplified speakers do not provide
sufficient volume for comfortable listening.
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.
Transferring Data to and from Another Scanner or a PC
You can transfer the programmed data to and from another PRO-97 scanner using a connecting cable
which has 1 /8 -inch phone plugs on both ends (not supplied). Connect the cable between each scanner's
PC/IF jacks. See “Cloning the Programmed Data” on Page XX. 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.
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 XX for the frequency list). You
can even change the frequency range on one of the SEARCH banks (SR5) to limit the search.
When you find a frequency, you can store it into a programmable memory location called a channel, which
is grouped with 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.

UNDERSTANDING BANKS
Channel Storage Banks
20-527 Owner’s Manual Draft
Page 12 of 60
A bank is a storage area for a group of channels. Channels are storage areas for frequencies. Whereas a
channel can only contain one frequency, a bank can hold numerous channels.
To make it easier to identify and select the channels you want to listen to, your scanner divides the
channels into 10 banks (0 to 9) of 100 (00 to 99) channels each, a total of 1,000 channels. You can use
each channel-storage bank to group frequencies, such as those used by Motorola trunking, EDACS
trunking, LTR trunking, Marine, CB, Police, Fire, Aircraft and Ham (see “Typical Band Usage (in MHz)” on
Page XX).
For example, a police department might use four frequencies, one for each side of town. You could
program the police frequencies starting with 000 (the first channel in bank 0) and program the fire
department frequencies starting with 100 (the first channel in bank 1). The first digit identifies the bank (0
to 9). The second and third digits identify the channel within the bank (00 to 99).
Search Banks
Your scanner has five preprogrammed search banks and one limit search bank. You can set the lower
and higher frequency limit in the limit search bank.
Note: For example, if you wanted to find active frequencies between a range of 150.1000 and 150.5000,
you would put both of those frequencies in the limit search bank.
For the default setting, see “Searching a Preprogrammed Frequency Range” on Page XX.
UNDERSTANDING YOUR SCANNER’S MODES
You can program each channel with any of seven receive modes (AM, FM, CT, DC, MO, ED, and LT).
Each receive mode affects how your scanner operates when scanning and receiving transmissions.
Notes:
. Trunked modes (MO, ED and LT) can only be selected for frequencies above 137 MHz.
. Your scanner’s closed mode lets you hear only those trunking talkgroups you specify. For more
information, see “Open and Closed Modes” on Page XX.
AM Mode
The AM mode sets the scanner to receive transmissions using amplitude modulation (AM), primarily used
for aircraft, military, some amateur radio, and some government transmissions. (Refer to “Specifications”
on Page XX for a list of the frequencies covered.) When the scanner receives a transmission on a channel
set to the AM mode, it always stops on the transmission.
20-527 Owner’s Manual Draft
Page 13 of 60
FM Mode
The FM mode sets the scanner to receive transmissions using frequency modulation (FM), 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.
CTCSS Mode (CT)
CTCSS mode sets the scanner to receive transmissions using frequency modulation (FM) with
Continuous Tone Coded Squelch System (CTCSS) subaudible tone codes. CTCSS allows multiple users
to share a single radio frequency without hearing each other’s transmissions. In your PRO-97 scanner,
the CTCSS feature can be used to block the reception of transmissions on shared channel to only those
that use the CTCSS mode also features a Code Search setting that allows you to instantly display and
store unknown codes into the channel memory. CTCSS tones can sometimes be heard as a low “hum” in
the background of a voice transmission. Many systems that use CTCSS transmit a special “turn off code”
at the end of each transmission. The turn off code causes a properly equipped receiver to mute before
the transmission ends, eliminating the “squelch tail” burst of noise the commonly occurs when the signal
is lost. CTCSS turn off code performance can be affected by weak signals.
DCS Mode (DC)
DCS mode sets the scanner to receive transmissions using frequency modulation (FM) with Digital
Coded Squelch (DCS) subaudible data signaling. DCS is very similar to CTCSS, except that a digital
code is transmitted instead of an audio tone. Like CTCSS, DCS allows multiple users to share a single
radio frequency without hearing each other’s transmissions. In your PRO-97 scanner, the DCS feature
can be used to block the reception of transmissions on a shared channel to only those that use the DCS
tone that you have specified. DCS mode also features a Code Search setting that allows you to instantly
display and store unknown codes into the channel memory. DCS data can sometimes be heard as a low
“purring” sound in the background of a voice transmission. Some DCS systems transmit a special “turn
off code” at the end of each transmission. The turn off code causes a properly equipped receiver to mute
before the transmission ends, eliminating the “squelch tail” burst of noise the commonly occurs when the
signal is lost.
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 five) 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,
20-527 Owner’s Manual Draft
Page 14 of 60
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 II 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.
Notes:
. 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.
. Tuning the scanner to an active control channel while in Motorola mode will display the Motorola
System. ID and the approximate control channel message decode success rate. This information can
help you identify the Motorola trunking system that you are monitoring and the receive quality of the
control channel signal.
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 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.
EDACS Mode
20-527 Owner’s Manual Draft
Page 15 of 60
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 0001 to 2047 or AFS (Agency Fleet Subfleet) number from 00-001 to 15-157.
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 with IDs that match talk group IDs you have stored in the bank's talk
group ID list which are 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.
LTR 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. There 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)
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
20-527 Owner’s Manual Draft

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.
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 Motorola, EDACS, and LTR systems).
Notes:
• In open mode, you hear all active talk groups except those you specifically exclude, making it easy to
hear everything going on. In closed mode, you hear only those talk groups you specify. This makes it
easy to listen only to talk groups you are interested in and exclude others.
• When you select a channel manually, any transmission opens squelch, regardless of the current mode.
• When no ID code is programmed into the scanner, it receives the signal in MO, ED, or LT mode. In
open mode, the scanner stops on any transmission. If the ID is stored, the text tag appears on the
display. Otherwise, the talk group ID appears on the display. In closed mode, the scanner only stops on
a transmission if the ID is stored.
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. The scanner stops on any ID code
and only uses the ID list to look up ID text tags.
In closed mode, the scanner stops only on signals that have an ID code which is found in the ID list for
the bank. Also, the scanner scans signals transmitted only under the following conditions:
• When the signals are in the FM mode.
• When the signals are in the MO, ED, or LT mode and the signal’s ID code matches the programmed ID
code
You can also select the user or talk groups you want the scanner to receive in closed mode.
When you set a channel storage bank to open mode, + appears under the bank’s number while scanning.
When you set a channel storage bank to closed mode, - appears under the channel storage bank’s
number while scanning. 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 XX for
more information about setting the open and closed modes.

OPERATION
Turning on the Scanner and Setting Squelch
1. To turn on the scanner, turn VOLUME clockwise. Multi-system Trunking Scanner appears. After about
3 seconds, you might hear a hissing sound. Then adjust VOLUME to a comfortable level.
2. Turn SQUELCH fully counterclockwise until the indicator points to MIN, then turn SQUELCH clockwise
until the hissing sound stops.
3. To turn off the scanner, turn VOLUME counterclockwise to OFF.
Notes:
• The scanner does not scan if there are no frequencies stored in channels. If the scanner does not scan
and you have already stored frequencies in channels, turn SQUELCH further clockwise.
• If the scanner picks up unwanted, partial, or very weak transmissions, turn SQUELCH clockwise to
decrease the scanner’s sensitivity to these signals. If you want to listen to a weak or distant station, turn
SQUELCH counterclockwise.
• If SQUELCH is adjusted so you always hear a hissing sound, the scanner will not scan properly.
• To ensure the scanner operates properly while in the trunking mode, we suggest you set SQUELCH
using the steps listed above.
Storing Known Frequencies into Channels
Good references for active frequencies are RadioShack’s Police Call, Aeronautical Frequency Directory,
and Maritime Frequency Directory. We update these directories every year, so be sure to get a current
copy. Also see the supplied Trunking Guide.
Follow these steps to store frequencies in to channels.
Notes:
• If you are storing frequencies for an EDACS system, you must store them in order, with the first
frequency in channel 1 for the current bank. For example, if you want to store frequency of 150.0100,
150.0200, 150.0300, and 150.0400 MHz, you must store them in Channels 1, 2, 3, and 4 respectively.
• When M is on the display, you can also select your desired bank and channel number with the FUNC
and arrow keys.
1. Press MANUAL, enter the bank (0-9) and channel number (00-99) where you want to store a
frequency, then press MANUAL again. M and the bank and channel number appear at the upper left
corner of the display (for example: M000).

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 then stops within a few seconds on the strongest weather broadcast.
SAME Standby Mode
The National Weather Service precedes each weather alert with a digitally encoded SAME (Specific Area
Message Encoding) signal, then a 1050 Hz tone. The SAME signal includes a FIPS (Federal Information
Processing Standard) area code, and an event code that corresponds with the type of alert being sent.
You can configure your scanner to operate in SAME Standby mode, where it monitors a selected weather
radio station for SAME alerts for areas you specify. You can program your scanner with up to 10 FIPS
codes for the areas you desire. The National Weather Service maintains a current list of FIPS codes at
http://www.nws.noaa.gov/nwr/.
To configure your scanner for SAME Standby mode, follow these steps:
1. Press WX until you identify the weather station with the strongest signal for your location.
2. Press FUNC, and the PROG to access the FIPS code entry table.
3. Use the ^ or v keys to select the desired FIPS code storage location.
4. Use the numeric keys to enter the desired FIPS code, and then press ENTER to store the code. Press
TEXT to label the code entry with an alphanumeric text table if desired. Repeat this process for all the
FIPS codes that you wish to store.
5. Press L/OUT to lock out or enable specific FIPS entries.

Priority
In addition to the 1,000 programmable memory channels, the scanner has one priority channel.
20-527 Owner’s Manual Draft
Page 34 of 60
With the priority feature, you can scan through programmed channels and still not miss an important or
interesting transmission on a specific channel. When 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.
Notes:
• The priority feature does not operate while the scanner receives a trunking voice channel or during
trunking delay time. Therefore, the priority check seems random during peak hours.
• If you program a weather channel as the priority channel, the scanner stays in the priority channel only
when the scanner detects the weather alert tone.
• This scanner cannot set a channel as the priority channel if the channel’s receive mode is MOT, ED, or
LTR.
To program a frequency in the priority channel:
1. Press MANUAL.
2. Use the number keys to enter the channel number which contains the frequency you want to program
as the priority channel. Then press MANUAL again.
3. Press FUNC then PRI. Priority Channel blinks.
To program the priority channel directly:
1. Press PGM.
2. Press PRI.
3. Enter the frequency you want to enter into the priority channel, then press ENTER.
To program a weather channel as the priority channel:

To turn on the priority feature, press PRI so pri changes PRI on the display while scanning. If the scanner
detects activity on the priority channel, Priority Channel appears. Or if the scanner detects a weather
alert tone in Priority WX mode, Priority Channel! appears for 3 seconds then changes to Weather ALERT
and the scanner sounds an alert tone (see “Displaying Weather Messages” on Page XX).
20-527 Owner’s Manual Draft
Page 35 of 60
Notes:
• Priority WX is only for receiving a weather alert.
• When the scanner detects a 1050 Hz alert tone, priority WX activates and you receive a weather alert.
• If you program a weather frequency into the priority channel and the scanner detects a weather alert
tone on that frequency, the scanner sounds the alert tone.
To turn off the priority feature, press PRI.
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 trunking transmissions in closed mode, you might have to change the receive
mode.
To change the receive mode, repeatedly press MODE. The receive mode changes as follows:
AM – accesses the AM mode
FM – accesses the FM mode
CT – accesses the FM mode, CTCSS System
DC – accesses the FM mode, DCT System
MO – accesses the FM Mode, Motorola Trunking System (with a 4- or 5-digit ID code)
ED – accesses the FM Mode, EDACS Trunking System (with 4-digit decimal ID code or 5-digit AFS
code)
LT – accesses the FM mode, LTR Trunking System (with 6-digit ID code)
Note: MO (MOT), ED, and LT modes are not available when the scanner tunes up or down through the
frequency ranges in which the trunking operation is not used.
Using the Attenuator
To reduce interference or noise caused by strong signals, you can reduce the scanner’s sensitivity to
these signals.
There are two attenuator modes in your scanner. One is normal attenuator mode in which you set the
attenuator in each channel or each band/group in the search and tune mode. The other is global mode in
which you set the attenuator only once. This setting is applied all the time in every mode.
Press ATT to turn on or off the attenuator while the channel number is indicated or while the scanner is

TRUNKING
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 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 control frequencies for Motorola systems or all
the trunking group frequencies for EDACS and LTR in one bank (see “Storing Known Frequencies into
Channels” on Page XX) and input ID codes in the ID memory (see “Storing Talk Group IDs” on Page XX).
Your PRO-97 automatically calculates Motorola voice channel frequencies when it decodes the control
channel. This eliminates the need to enter all the Motorola group frequencies.
The control channels are subject to change depending on the day. Therefore enter all the control
frequencies in the same bank. If you do not know which is the control channel, it is better to enter all the
system frequencies into the same bank.
When the scanner decodes the Motorola control channel and finds the voice channel, the scanner
displays the control channel memory location on the top line, the received frequency with VC (voice
channel) on the second line, the bank and control channel memory location number on the third line and
the Motorola ID number on the bottom line.
IMPORTANT: To listen to the transmission, the mode of the programmed channel must be the same as
that of the trunking channel (MO, ED, or LT).
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.
Notes:
• 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,
20-527 Owner’s Manual Draft
Page 39 of 60
but the display will alternate between all active IDs.
• Frequency fleet map and talk group information are also widely available on the Internet, (for example, at
www.trunkscanner.com).
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.
Your 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 406 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.
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 the same as non-trunked frequencies, except that you must store the
appropriate mode (MO, ED, or LT) with each frequency.
Notes:
• You can scan only one type of trunked frequency, either EDACS, Motorola, or LTR in a bank at one time.
You can, however, mix conventional channels and frequencies in a bank.
• 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 XX).
• If you are programming frequencies for an EDACS system you must store them in the Logical Channel
Number order (usually listed as LCN#). For example, LCN1 would go into channel 01 for the current bank,
and LCN2 would go into channel 02.
• If you are programming frequencies for an LTR system you must store them in the home repeater order.
For example, home repeater order 1 would go into channel 01 for the current bank, and home repeater
order 2 would go into channel 02.

control channel. You must program the system’s base frequency and offset frequency to do this.
Note: 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 www.trunkscanner.com, other Internet
sources, or locally published guidebooks.

A GENERAL GUIDE TO FREQUENCIES
Reception of the frequencies covered by your scanner is mainly “line-of-sight.” That means you usually
cannot hear stations that are beyond the horizon.
US Weather Frequencies (in MHz)
162.400 162.425 162.450
162.475 162.500 162.525

Ham Radio Frequencies
Ham radio operators often transmit emergency information when other means of communication break
down. The chart below shows the frequencies the scanner receives that ham radio operators normally
use.
Wavelength Frequencies (MHz)
10-Meter 28.000–29.700
6-Meter 50.000–54.000
2-Meter 144.000–148.000
70-cm 420.000–450.000
33-cm 902.000–928.000
25-cm 1240.000–1300.000
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 frequencies, you hear only noise on that frequency. If the interference is not severe, you might be
able to turn SQUELCH clockwise to omit the birdie.
The scanner’s birdie frequencies (in MHz) are:
Add birdie frequencies
To find the birdies in your scanner, begin by disconnecting 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 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) x 1000 = 30,620 kHz
To convert from kHz to MHz, divide the number of kilohertz by 1,000:
20-527 Owner’s Manual Draft
Page 57 of 60
127,800 (kHz) / 1000 = 127.8 MHz
To convert MHz to meters, divide 300 by the number of megahertz:
300/50 MHz = 6 meters

INITIALIZING THE SCANNER
Important: This procedure clears all information you stored in the scanner’s memory. Initialize the
scanner only when you are sure the scanner is not working properly.
Note: You can save the information in your scanner’s memory into your computer or another scanner
before trying to initialize it. See “Transferring Data to and from Another Scanner or a PC” on Page XX.
1. Turn off the scanner, then turn it on again. Multi-system Trunking Scanner appears.
2. Press 0 then 1 while Multi-system Trunking Scanner appears. Initializing please stand by. appears for
about 5 seconds.
Note: Do not turn off the scanner until the initialization is complete. When the initialization is complete,
M000 appears on the top line of the display. Bank 0 Ch 00 appears on the third line.
CARE
Keep the scanner dry; if it gets wet, wipe it dry immediately. Use and store the scanner only in normal
temperature environments. Handle the scanner carefully; do not drop it. Keep the scanner away from
dust and dirt, and wipe it with a damp cloth occasionally to keep it looking new.
Modifying or tampering with the scanner’s internal components can cause a malfunction and might
invalidate its warranty an 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.
