Features
Your RadioShack 1000-Channel Handheld Trunking Scanner is one of a new generation of scanners designed
to track Motorola® Type I, Type II, hybrid analog systems, (such as Smartnet® and Privacy Plus®) plus
M/A-COM EDACS® and EF Johnson LTR. Those systems 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 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 (on a different frequency called a data channel) 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 scanner lets you select and monitor the data channel
frequency 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 it is preprogrammed with service 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 37,000 exciting frequencies, including police and fire departments,
ambulance services, and amateur radio services, and you can change your selection at any time.
Your scanner also has these special features:
Signal Stalker—you can set the scanner so it detects and provides information about nearby radio
transmissions.
Triple-Conversion Circuitry — virtually eliminates any interference from IF (intermediate frequency) images,
so you hear only the selected frequency.
100 Channel-Storage Banks — you can store up to 100 channels in each of 10 different banks, for a total of
1000 channels, so you can more easily identify calls.
Ten Scan Lists — you can store up to 100 trunking talk group IDs in each trunk scanning bank.
Digital Weather Alert — uses the digital SAME (specific area message encoding) signal transmitted with
weather alerts to identify the type of alert being issued.
Note: This scanner does not use the specific area feature of SAME. It responds to all alerts received.
Two-Second 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 talk group IDs when tracking trunked systems.
Priority Channels — lets you program one channel in each bank (10 in all) and then have the scanner check
that channel every 2 seconds while it scans the bank, so you do not miss transmissions on those channels.
Four Service Banks — frequencies are preset in separate police (fire/emergency), aircraft, ham, marine to
make it easy to locate specific types of calls.
Weather Banks— frequencies are preset and allows the scanner to search 7 weather channels (NOAA,
weather)
Auto Backlight — automatically turns on the backlight when the scanner receives signals.
Simultaneous Trunking Operation — allows the scanner to trunk three trunking systems, Motorola and
EDACS, at the same time, as well as conventional systems.
Hypersearch — lets you set the scanner to search at up to 270 steps per second in frequency bands with 5
kHz steps, compared to the normal search speed of 90 steps per second.
Hyperscan — the scanner automatically scans up to 90 channels per second to help you quickly find
interesting broadcasts.
Key Lock — lets you lock the scanner’s keys to help prevent accidental changes to the scanner’s
programming.
Data Signal Skip — lets you set the scanner to skip non-modulated or data signals (such as fax or modem
transmissions) during scan and searches. This lets the scanner avoid non-voice signals, making a search
faster.
Disconnect Tone Detect — the scanner automatically tunes to the trunking data channel when it receives a
disconnect transmission. You can turn this off, so you can continuously monitor a channel with a weak
transmission where conversations are often disconnected.
Manual Access — lets you directly access any channel.
Liquid-Crystal Display — makes it easy to view and change programming information.
Display Backlight — makes the scanner easy to read in low-light situations.
Key Backlight — makes the keys easy to read in low-light situations.
Flexible Antenna with BNC Connector — provides adequate reception in strong signal areas and is designed
to help prevent antenna breakage. Or, you can connect an external antenna for better reception.
Memory Backup — keeps the frequencies stored in memory for an extended time if the scanner loses power.
Wired Programming— you can connect your scanner to a personal computer and program frequencies into it
using an optional interface cable and software.
Three Power Options — let you power the scanner using internal batteries, external AC power using an
optional AC adapter/charger, or DC power using an optional DC cigarette-lighter power cable.
Key Confirmation Tones — the scanner sounds a tone when you perform an operation correctly, and an error
tone if you make an error.
Battery Save — saves battery power when the scanner does not detect any transmissions for more than 5
seconds when a channel is manually selected.
Battery Low Alert — warns you when battery power gets low.
Weather Alert Indicator — your scanner also functions as a severe weather alert monitor.
Your scanner can receive these bands:

FCC NOTICE
SCANNING LEGALLY
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), as amended, 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 is designed to prevent reception of illegal transmissions, in compliance with the law which requires
that scanners be manufactured in such a way 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 it is not
legal to listen to. Doing so could subject you to legal penalties.
We encourage responsible, legal scanner use.
Preparation
You can power your scanner from any of three sources:
• internal batteries (not supplied)
• standard AC power (using an optional AC adapter)
• vehicle battery power (using an optional DC adapter)
USING INTERNAL BATTERIES
You can power your scanner using four alkaline or rechargeable (Ni-MH) AA batteries (not supplied). For the
best performance and longest life, we recommend RadioShack batteries.
Using Non-Rechargeable Batteries
Follow these steps to install non-rechargeable batteries.
1. Turn VOLUME/OFF counterclockwise until it clicks to make sure the power is turned off.
2. Slide up and hold the tab on the back of the scanner, then pull up the battery compartment cover
from the top edge.
3. Before you install alkaline or any other nonrechargeable batteries, use a pointed object such
as a ballpoint pen to set ALKALINE JACK Ni-MH inside the compartment to ALKALINE.
Warning: Set ALKALINE JACK Ni-MH to NI-MH for use only with or nickel metal hydride
(Ni-MH) rechargeable batteries. Never attempt to recharge non-rechargeable batteries.
Non-rechargeable batteries can get hot or explode if you try to recharge them.
4. Install two batteries in the compartment and two in the cover as indicated by the polarity symbols (+
and –) marked inside those locations.
Cautions:
• Use only fresh batteries of the required size and ecommended 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 (standard, alkaline, or rechargeable),
or rechargeable batteries of different capacities.
5. Replace the cover, inserting the lower tabs first.
When flashes and the scanner beeps every 15 seconds, replace all four batteries.
Warning: Always dispose of old batteries promptly and properly. Do not bury or burn them.
Using Rechargeable Batteries
You can also use four rechargeable batteries. Before you use Ni-MH batteries, you must charge
them.
The scanner has a built-in circuit that lets you recharge Ni-MH batteries while they are in the scanner.
To charge the batteries, set ALKALINE JACK Ni-MH to NI-MH, install the batteries in the scanner, and
connect an external AC or DC adapter to the scanner’s POWER jack (see “Using AC Power” on Page XX or
“Using Vehicle Battery Power” on Page XX).
Warning: Do not connect either adapter to the scanner if non-rechargeable batteries (such as alkaline
batteries) are installed in the scanner and ALKALINE JACK NI-MH is set to NI-MH, or if you are unsure of
the switch’s position. Non-rechargeable batteries will get hot and can even explode if you try to recharge them.
The scanner stops charging automatically after 14 hour since DC Jack was connected.
Notes:
• NiMH batteries last longer and deliver more power if you occasionally let them fully discharge. To do this,
simply use the scanner until it beeps every 15 seconds and flashes.
• To prevent damage to NiCd batteries, never charge them in an area where the temperature is above
113°F (40°C) or below 40°F (4°C). (If you need the note on NiMH temperature, please revise this
sentence)
Important: This scanner can use Ni-Cd
rechargeable batteries. At the end of a
Ni-Cd 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 1-800-822-8837. Some
options that might be available are: municipal curbside
collection, drop-off boxes at retailers such as your local
RadioShack store, recycling collection centers, and mailback
programs.
(If you need the “Important” on NiMH, please revise this sentence)
USING AC POWER
You can power the scanner using an 9V, 300 mA AC adapter and a size C Adaptaplug™ adapter (neither
supplied). Both are 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 DC 9V 300mA
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 use the scanner on AC power.
1. Turn VOLUME/OFF counterclockwise until it clicks to make sure the power is turned off.
2. Insert the Adaptaplug into the AC adapter’s cord so it reads TIP –. Insert the Adaptaplug into the
scanner’s POWER 9V 300ｍA jack.
3. Plug the AC adapter into a standard AC outlet.
If rechargeable batteries are installed and ALKALINE JACK NI-MH is set to NI-MH, the adapter powers
the scanner and recharges the installed batteries at the same time. If the installed batteries are inappropriate,
the scanner stops the charging and displays ERR CHArg. If you see the message, do not use the
batteries.
Note: This is a rare case but scanner displays ERR CHArg although the installed batteries are
appropriate. If the scanner displays ERR CHArg, please try to charge several times.
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 (neither supplied). Both are available at your local RadioShack
store.
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 DC 9V 300 mA
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.
• If batteries are installed, make sure the battery switch inside the battery compartment is set to the
correct position (see “Using Internal Batteries” on Page XX).
1. Turn VOLUME/OFF counterclockwise until it clicks to make sure the power is turned off.
2. If the adapter has a voltage switch, set the switch to 9V.
3. Insert the Adaptaplug into the DC adapter’s cord so it reads TIP –. Insert the Adaptaplug into the
scanner’s DC 9V 300 mA jack.
4. Plug the other end of the adapter into your vehicle’s cigarette-lighter socket.
If rechargeable batteries are installed and ALKALINE
JACK NI-MH is set to NI-MH, the adapter powers the scanner and recharges the installed batteries at the
same time.
Note: If the scanner does not operate properly when you use a DC adapter, unplug the adapter from the
cigarette-lighter socket and clean the socket to remove ashes and debris.
CONNECTING THE ANTENNA
To attach the supplied flexible antenna to the connector on the top of your scanner, align the slots around the
antenna’s connector with the tabs on the scanner’s BNC connector. Then slide the antenna’s connector down
over the scanner’s connector and rotate the antenna connector’s outer ring clockwise until it locks into place.
Connecting an Optional Antenna
The scanner’s BNC connector makes it easy to connect a variety of optional antennas, including an external
mobile antenna or outdoor base station antenna. Your local RadioShack store sells a wide selection of
antennas.
Note: Always use 50-ohm, RG-58, or RG-8, coaxial cable to connect an outdoor antenna. If the antenna is over
50 feet from the scanner, use RG-8 low-loss dielectric coaxial cable. If your antenna’s cable does not have a
BNC connector, your local RadioShack store carries a variety of BNC adapters.
CONNECTING AN EARPHONE/ HEADPHONE
For private listening, you can plug an optional earphone
or mono headphones into the jack on top of your scanner.
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 high-volume listening can lead to permanent 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 volume level that does not cause discomfort might still damage your hearing.
Traffic Safety
Do not use an earphone or headphones with your scanner when operating a motor vehicle in or near traffic.
Doing so can create a traffic hazard and could be illegal in some areas.
If you use an earphone or headphones with your scanner, be very careful. Do not listen to a continuous
broadcast. Even though some earphones/headphones let you hear some outside sounds when listening at
normal volume levels, they still can present a traffic hazard.
CONNECTING AN EXTENSION
SPEAKER
In a noisy area, an optional extension speaker, positioned in the right place, might provide more comfortable
listening. Plug the speaker cable’s
1/ 8-inch (3.5-mm) mini-plug into your scanner’s jack. Your local
RadioShack store carries a selection of suitable speakers.
ATTACHING THE BELT CLIP
To make your scanner easier to carry when you are on the go, use the supplied belt clip. Use a Phillips
screwdriver and the supplied screws to attach the clip to the scanner.
About Your Scanner
We use a few simple terms in this manual to explain the features of the scanner. Familiarize yourself with these
terms and the scanner’s features, and you can put the scanner to work for you right away. Simply determine the
type of communications you want to receive, then set the scanner to scan those communications.
The scanner scans conventional frequencies and trunked systems. For more information about trunked
transmissions see “Trunking Operation” on Page XX.
A frequency, expressed in kHz or MHz, is the tuning location of a station. To find active frequencies, you use
the search function or refer to a frequency reference such as the included Trunking Frequency Guide.
Besides searching within a selected frequency range, you can also search your scanner’s service banks.
Service banks are preset groups of frequencies categorized by the type of services that use those frequencies.
For example, many amateur radio frequencies are located in the HAM service bank.
When you search and find a desired frequency, you can store it into a programmable memory location called a
channel. Channels are grouped into channel-storage banks. The scanner has 1000 channels in
channel-storage bank. Each bank is divided into ten 100-channel sets. You can scan the channel-storage
banks to see if there is activity on the frequencies stored there.
Just keep in mind — you search frequencies and scan channels.

UNDERSTANDING BANKS
Service Banks
The scanner is preprogrammed with all the frequencies allocated to the ham, marine, aircraft, and police
(fire/emergency) services. This helps you quickly find active frequencies instead of doing a chain search (see
“Service Bank Search” on Page XX).
Channel Storage Banks
To make it easier to identify and select the channels you want to listen to, all the channels are divided into 10
banks of 100 channels. Use each channel-storage bank to group frequencies, such as those for the police
department, fire department, ambulance services, or aircraft (see “Guide to the Action Bands” on Page XX).
For example, the police department might use four frequencies in your town while the fire department uses an
additional four. You could program the four police frequencies starting with Channel 1 (the first channel in
bank 1), and program the fire department frequencies starting with Channel 51 (the first channel in bank 2).
S
Operation
TURNING ON THE SCANNER AND SETTING SQUELCH

3. If the scanner is scanning, press SCAN/MANUAL to stop scanning, then turn SQUELCH clockwise until the
hissing stops.
STORING KNOWN FREQUENCIES INTO CHANNELS
You can locate and store specific frequencies into channels for later use. To assist you in locating a desired
frequency from the scanner’s wide range, consider using a frequency guide. Good references for active
frequencies are the RadioShack Police Call Guide including Fire and Emergency Services, and Official
Aeronautical Frequency Directory. We update these directories every year, so be sure to get a current copy.
Note: To store trunked system frequencies, see “Storing Trunked Frequencies” on Page xx.
Follow these steps to store frequencies into channels.

SCANNING THE STORED CHANNELS
To begin scanning channels, press SCAN/MANUAL. The scanner scans through all non-locked channels in the
activated banks. (See “Locking Out Channels” on Page XX and “Turning Channel-Storage Banks On and Off”
on Page XX). When the scanner finds a transmission, it stops on it. When the transmission ends,
the scanner resumes scanning.
Notes:
• If you have not stored frequencies into any channels, the scanner does not scan.
• If the scanner picks up unwanted partial, or very weak transmissions,
turn SQUELCH clockwise to decrease the scanner’s sensitivity to these signals.
To listen to a weak or distant station, turn SQUELCH counterclockwise.
•To ensure proper scanning, adjust SQUELCH until the audio mutes.
• To scan in the trunk scanning mode, see “Trunking Operation” on Page XX.
MANUALLY SELECTING A CHANNEL

broadcast on a channel and do not want to miss any details —even though there might be periods of silence —
or if you want to monitor a specific channel.
Press E/PGM to put the scanner in programming mode. PGM appears.
Or, during scanning, if the radio stops at a channel you want to listen to, press HOLD/RESUME. Press
HOLD/RESUME to resume automatic scanning.
Special Features
DELAY
Sometimes a user might pause before replying to a transmission. To avoid missing a reply on a specific
channel, the scanner automatically program a 2-second delay into any channel or frequency. You can monitor
the channel frequency for an additional 2 seconds after the transmission stops before resuming scanning or
searching.
Depending on how the scanner is operating, follow one of these steps to program a delay.
• To turn off the 2-second delay, press ・/CLR /DELAY while the scanner is monitoring a channel, scanning,
or searching. DLY disappears.
• To turn on the 2-second delay to a channel again, select the channel and press・/CLR /DELAY. DLY
appears.
• To turn on the 2-second delay to search again, press ・/CLR /DELAY while the scanner is searching.
DLY appears and the scanner automatically adds a 2-second delay to every frequency it stops on in
that band.
Signal Stalker also has a delay feature. It's delay time is 10 seconds. See page XX how to program Signal
Stalker Delay.
TURNING CHANNEL-STORAGE BANKS ON AND OFF
You can turn each channel-storage bank on and off. When you turn off a bank, the scanner does not scan
any of the 100 channels in that bank.
While scanning, press the number key that corresponds to the bank you want to turn on or off. Numbers appear
at the top of the display, showing the currently selected banks. The scanner scans all the channels within the
displayed banks that are not locked out (see “Locking Out Channels”). The bank number flashes when the
scanner scans a channel that belongs to the bank.
Notes:
• You can manually select any channel within a bank, even if that bank is turned off.
• One bank must always be active. If you try to turn off all banks, bank 1 remains.
LOCKING OUT CHANNELS
You can increase the scanning speed by locking out channels that have a continuous transmission, such as a
weather channel. To lock out a channel, manually select the channel, then press L/O. L/O appears.
Note: You can still manually select locked-out channels.
To remove the lockout from a channel, manually select the channel, then press L/O. L/O disappears.
To unlock all channels in the banks that are turned on, press HOLD/RESUME to stop scanning, then hold down
L/O until the scanner beeps twice.
PRIORITY
The priority feature lets you scan through the channels and still not miss important or interesting calls on specific
channels. You can program one stored channel in each bank as a priority channel. If the priority feature is
turned on, as the scanner scans the bank, it checks that bank’s priority channel for activity every 2 seconds.
The scanner automatically designates each bank’s first channel as its priority channel. Follow these steps to
select a different channel in a bank as the priority channel.
1. Press PGM
2. Enter the channel number you want to select as the priority channel, then press PRI.

RECEIVING NWR-SAME AND WEATHER ALERT SIGNALS
In 1994, the National Oceanic and Aerospace Administration (NOAA) began broadcasting alerts that include
digitally encoded data. Specific Area Message Encoding (SAME) includes information which identifies the
severity of the alert. While this scanner does not encode specific geographical data, it does detect SAME
signals and decode the alert level. The scanner displays this data as codes corresponding to the levels of
severity (L1, L2, and L3).
Turning On the Digital Weather Alert Feature
1. Press WX/ and start weather search. See “Weather Search” on Page XX.
2. Press 6/ALERT. ALERT appears. This mutes the audio until the scanner receives a SAME-coded
signal.
When the scanner receives a SAME-coded signal, ALERT flashes and an associated “L” code (which
indicates the severity of the alert) and SAME-coded signal appears alternately. The scanner remains on the
weather channel and the audio turns on so you can hear the weather broadcast.
The scanner displays one of the following codes to indicate the alert level .
L1: Warning
L2: Watch
L3: Advisory
WXA: Weather Alert
Testing Digital Weather Alert Tone
To hear and test the tones for the three alert levels, press WX/ to select the weather service, then hold
down ALERT for about 1 second. The tones sound in the order L3, L2, then L1, and TEST flashes. Each alert
code appears as its tone sounds. Press any key to end the test sequence.
Programming a FIPS Code
To specify a county, SAME uses a standard established by the US Census bureau, called FIPS.
The format of a FIPS code is:
PSSCCC, where...
P = area subdivision (0=entire area)
SS = State code (00=all states)
CCC = County code (000=all counties)
For example, the FIPS code for Tarrant County, Texas is:
048439 (48=Texas; 439=Tarrant County).
Some counties are further subdivided, in which cases, the first digit will be 0 for all subdivisions
in the county and each subdivision will be labeled 1-9.
To program your scanner to alert you when the weather service issues an alert,
you must set the scanner to the alert mode, and then leave the scanner monitoring the weather
service. You cannot scan frequencies and monitor for weather alerts at the same time.
To limit weather alerts to a specific area, you must also program in the FIPS code(s) for the area(s) you want to
receive alerts. The scanner can be set to either, alert for all areas, or only the areas you have programmed.
programming FIPS
During weather scan hold mode, press E/PGM. The scanner sends itself into FIPS programming mode. If the
scanner is set to alert for all FIPS, ALLFIPS appears on the display.
If the scanner is set to alert only the area you have programmed, F1 appears.
press or to change the displayed FIPS code from F1 to F15.
If a FIPS code is not programmed, ------- appears.
Use the keypad to enter the FIPS code. Press ・/CLR /DELAY to cancel an inputted FIPS code.
Press E/PGM to store the FIPS code. Press 0 then E/PGM to clear a FIPS code. ------ appears.
If an invalid value has been inputted, the FIPS code is cleared.
To set the scanner so it alerts you when you receive any FIPS code, press or
to move ALLFIPS. Then press E/PGM. Then go to WX hold mode.
To set to alert only the area you have programmed, press or to move F1 to F15.
Then press E/PGM. Then go to WX hold.
Skywarn
The Skywarn function lets you jump directly to the last channel in memory (Channel 1000)
from any mode by press and holding . The scanner goes into scan hold mode
and starts receiving transmissions in the last channel. If no frequency is programmed in the last channel,
No Prog appears and the scanner sounds an error tone.
About Skywarn
Skywarn is an organized group of trained weather observers. A Skywarn group exists in virtually every US
county with a signifi cant population. During inclement weather, reports made by Skywarn observers include
information about:
• pea-sized and larger hail
• wind and wind gusts 40 MPH and greater
• heavy rainfall
• lightning (cloud-to-cloud and especially cloud-toground)
• wall clouds seen in severe thunderstorms (which spawn tornadoes)
• severe lowering of a wall cloud
• turbulence in a wall cloud
• funnel clouds
• tornadoes
• high water areas
• downed power lines
• other emergency conditions that affect life or property Listening to Skywarn broadcasts makes it easy to
quickly find out about and prepare for inclement weather conditions in your immediate area, even before your
local NOAA weather broadcast and local TV or radio station can announce them. Enter the local Skywarn
frequency for your area into Channel 1000 on your scanner. Then, listen to Skywarn fi rst when severe weather
threatens. Listen to NOAA: for weather alerts Listen to Skywarn to hear trained observers in your vicinity call in
offi cial reports to a net control station which relays those reports to NOAA and other emergency agencies.
Most importantly, you get Skywarn reports directly from trained observers - that means you get them several
minutes before they can be relayed for broadcast by NOAA and as much as 5 or 10 minutes sooner than you
will hear them on local TV or radio! Those few minutes can be worth a lot when it comes to deciding if your
family needs to take cover.
Note: If you tune to a Skywarn frequency when the Skywarn net is not active, you may hear nothing, or you may
hear amateur radio operators talking on a local repeater system.
Signal Stalker
Your scanner’ s Signal Stalker feature lets you set the scanner so it detects and then displays the frequency of
a nearby strong radio transmission. You can set the scanner so Signal Stalker works “in the background”
while you are scanning other frequencies; turn off normal scanning while Signal Stalker works;
or turn off Signal Stalker and use the scanner normally. You can set the scanner so it alerts you
when Signal Stalker finds a frequency. You can also set the frequency band where you want the scanner to look
for transmissions. You can also turn on the pager screening feature so the scanner ignores common pager
frequencies.
Note:
･Signal Stalker works well for locating the source of strong local transmissions,
such as mobile and handheld two way radios in areas with no other strong transmission
sources; however, if you are in an area with many transmission sources
(such as pager radio transmitters,multiuse radio towers, traffi c control devices, etc.),
Signal Stalker might not fi nd the transmission you are searching for, or it might find
A transmission other than the one you are searching for. You can screen unwanted
transmissions by pressing L/O to lock them out. See “Frequency Skip” for more information.
･ Signal Stalker cannot detect satellite dishes or any transmitter with a frequency above
or below the frequency ranges listed under “Setting the Signal Stalker Options”.
･ Signal Stalker works better with some types of transmissions than others.
It might not correctly display frequency information for transmitters using a highly
directive antenna (such as an amateur radio beam antenna), if there are many transmitters
operating at the same time in the same area, or if the transmitter is a
broadcast television station.

Trunking Operation
The scanner tracks transmissions that use the Motorola Type I, Type II, hybrid,
and EDACS and LTR analog trunking systems. The frequencies for many of the 800 MHz,
900 MHz, and EDACS and LTR public safety systems are listed in the separate
National Public Safety Trunked System Frequency Guide included with your scanner.
SETTING THE SCANNER TO THE TRUNKING MODE
Simultaneous Trunking
The scanner allows you to track up to 10 systems at a time. You can trunk scan or search and scan
conventional frequencies at the same time. You can also program conventional frequencies in the same bank
as trunking systems.
After the scanner is finished checking activity in the trunked system, it scans other conventional frequencies
in the bank. (Only trunking frequencies are programmed in trunk mode.)
If a system is inactive for 1 second and there are no conventional channels in the bank, the scanner starts
scanning the next selected trunk bank. If you turned DELAY on, the scanner starts scanning the next trunk
bank after about 2 seconds.
To scan both trunking and conventional banks, select the banks you wish to be active with trunking off, then
press TRUNK. The scanner begins scanning. To return to conventional scanning, press TRUNK again.
SETTING SQUELCH FOR THE TRUNKING MODE
For trunked reception, a good squelch setting is in the center of the range with the white marker pointing up. If it
is set too high, it could prevent your scanner from locking on the control channel reliably. If it is set too low, it will
slightly delay finding the control channel. The best setting is the same as for conventional reception and is
critical for monitoring trunked systems.
PROGRAMMING TRUNKED FREQUENCIES
Follow these steps to select, program, and store trunked frequencies.
1. If you are not in conventional programming mode, press E/PGM beforehand. Press TRUNK. Your
scanner beeps a tone. Then TRUNK appears and one or more bank numbers flash.
2. Press the number key (1-9 and 0) of the desired target storage bank.
Select one of the trunk systems by repeatedly pressing or to select a trunking system type,
then press E/PGM .
Note: You can select from the following six systems:
You See Trunk System
E1 Motorola Type I, and Hybrid
Ed EDACS Wide Band: 9600 baund
E2 – 800 Motorola Type II, 800 MHz frequencies
E2 – 900 Motorola Type II, 900 MHz frequencies
E2 – Hi Motorola Type II, VHF(136-174 MHz) frequencies
E2 – UHF Motorola Type II, UHF (400-512 MHz) frequencies
Ed – SCt EDACS Scat
Lt LTR
3. PROG F appears, then press E/PGM. The scanner automatically selects the first
channel in the selected banks.
4. Use the number keys to enter a valid frequency within the trunk system, then press E/PGM.
The bank number, the channel number, and E (EDACS) ,M (Motorola) or L (LTR) appears
depending upon the trunk system selected.
Notes:
• If you enter an invalid frequency (outside the selected range), the scanner beeps, the channel number
flashes and Error appears. If this happens, press ・/CLR /DELAY to clear the frequency, then repeat
the entry.
• For EDACS and LTR systems, you must enter the frequencies in logical channel number (LCN) order.
• If you try to enter a duplicate frequency in a bank, the scanner beeps and the channel which was
previously stored appears.
5. Press or to select the next channel in the bank.
6. Repeatedly press ・/CLR /DELAY to return back to Step 2. Repeat Steps 2 and 5 until all frequencies have
been entered.
7. Press SRCH to begin searching for the trunk’s data channel and scan conventional frequencies at the
same time.
As the scanner looks through the frequencies, you see them on the display.
When the scanner finds the controlling data channel, the scanner begins trunking.
SEARCHING A TRUNKED BANK
Once the data channel is acquired, the scanner begins a trunk search.
With the search function, you will be able to find all the active talk groups within the trunked system.
Press SCAN/MANUAL. You can switch to the trunk scan mode from the trunk search mode.
See “Scanning the Talk Group ID Lists” on Page XX.
While scanning conventional frequencies, follow the steps below to switch to the trunk mode
after the scanner finds the data channel.
1. Press TRUNK. The scanner begins scanning both trunking and conventional banks.
2. Hold down TRUNK for about 1 second. The scanner switches to the trunk scan mode.
3. Hold down TRUNK for about 1 second again. The scanner switches to the trunk search mode.
Hint: While searching, you may not know exactly to whom the talk group IDs are assigned until you listen
awhile. To locate talk group ID lists for your local police, fire, and other agencies, refer to frequency guides
available at your local RadioShack store or on internet sites such as www.trunkscanner.com. You can also
determine the type of agency you are listening to after a short while, be it a police, fire, or emergency medical
2-way radio user. Once you have identified the type of service, note the associated talk group ID of that unit
for future programming. See “Identifying a Trunked Frequency” on Page XX. Determining the service
associated with a talk group ID might take awhile, but discovering the ID owner of each signal is half the fun of
trunk scanning!
Turning a Trunked Bank On or Off
Press and hold SCAN/MAUNAL during trunk scanning. The selected trunked banks appear.
Press the bank number (0–9), to urn the desired bank on or off.
Skipping a Trunked Bank
You can scan conventional frequencies programmed in the same bank by holding down
about 1 second. If there is no conventional frequency, the scanner
scans the next bank.
Turning the Status Bit Ignore (S-Bit) On or Off
You can set how your scanner works with status bits (also called S-Bits),
letting you control how the scanner interprets and displays talk group IDs.
The last four bits of a Motorola Type II talk group ID (a binary 16-bit code) are the status bits.
In some systems, status bits identify special situations (such as an emergency status).
Your scanner is preset to assume that the status bits in a talk group ID are set to 0
and ignores them. For example, when the scanner receives the talk group ID
010111001110 0011, it reads the ID as 010111001110 0000 and converts the first 12 bits
of the ID to 23776 (the talk group ID). However, since the status bit value is 3
(0011 converted to decimal equals 3), the ID is actually 23779.
If you are scanning a Motorola Type I system and do not have a fleet map for that system,
you might have to turn off status bit ignore in order to determine the proper fleet map.
Important: If you are scanning any system other than a Motorola Type I system,
be sure status bit ignore is set to ON or you will miss some transmissions.
Follow these steps to turn status bit ignore on or off.
1. If you are not in conventional programming mode, press E/PGM beforehand. Press TRUNK.
2. Repeatedly press or to select Motorola TypeⅠand TypeⅡ, then press E/PGM.
3. Repeatedly press or to select S-bit, then press E/PGM.
Identifying a Trunked Frequency
While ID scanning (looking for IDs within a trunked system) or performing an ID search,
press to see the current trunked frequency. (The frequency flashes twice.) Then hold down
until a confirmation tone sounds and the ID and the frequency alternately appear.
To return to normal operation, press .
Selecting the EDACS Talk Group ID Format
Your scanner can also enter or display EDACS talk groups in decimal format (0-2047).
1. Select the trunking programming mode and the bank you want to change.
2. Press or to select EDACS, then press E/PGM.
3. Press or to select AFS, then press E/PGM.
4. Press or to select AFS ON or AFS OFF, then press E/PGM.
You can use this feature to translate decimal talk group lists to the much more powerful AFS format. It is very
easy to use. Be sure to become familiar with AFS partial entry, and your scanning will become far more fl exible
and efficient.
EDACS Talk Group ID Range Search
When your scanner searches EDACS talk group IDs, the scanner can search within a range you set for agency
or fleet listings. For example, if you want to search within the 01 agency, while in hold mode press 0, 1, ・/CLR
/DELAY then SRCH. Or if you want to search within the 01 agency and 01 fl eet, while trunking press 0, 1, ・/CLR
/DELAY, 0, 1, then SRCH.
To stop the ID range search, press e while the talk group is deactivated.
Using HOLD to Monitor an Active Talk Group ID
Follow these steps to stop scanning and keep the scanner tuned to a desired ID.
1. Press HOLD/RESUME. HOLD appears and the scanner stays on the current ID.
2. If you want to listen to (and hold) a different ID, use the number keys to enter that ID.
3. Press . HOLD flashes, then the scanner monitors the ID.
4. Press SRCH to resume searching for a data channel (trunk scanning).
Locking Out Talk Group IDs
Many municipal and commercial services use trunk systems to transmit signals from such devices as water
meter transmitters, door alarms, and traffic signals. Some signals are encrypted, as well, and most are not voice
signals. Since all these are assigned IDs just like other users, you may want to lock out reception of these
ID signals. You can lock out up to 100 IDs at one time.
Note: If you lock out an ID while searching, it is also locked out of the scan list(s).
See “Using Talk Group ID Lists” on Page XX.
To lock out an ID, press L/O when the ID appears. The ID is locked out, and the next active ID appears.
Unlocking a Single Talk Group ID
You can check all IDs already locked out.
1. Select the trunking programming mode and the bank you want to review.
2. When the selected trunked system is displayed, press E/PGM.
3. Use or to choose Id Lout, and press E/PGM.
4. Press L/O, the ID is unlocked and the next locked ID displays.
5. If you unlocked all locked IDs, the scanner displays Lo Non.
Unlocking All Talk Group IDs
Hold down L/O while searching until you hear two short beeps.
The scanner beeps twice. Press SRCH to resume the search.
Using Trunk Scanning Scan Delay
Sometimes a user might pause before replying to a transmission. You can set the scanner
to hold on an ID for 2 seconds to wait for a reply. That way, the scanner continues to monitor
the ID for 2 seconds after the transmission stops before resuming scanning.
Press ・/CLR /DELAY to turn trunk scanning scan delay on or off.
DLY appears when the scan delay is set to on.
Note: If you consistently miss responses even with scan delay turned on, change the default
system type or the fleet map being used. See “Scanning Type I and Hybrid
Trunked Systems” on Page XX.
Monitoring Talk Group IDs
You can use your scanner’s display to monitor the frequencies/talk group IDs
of a trunked system for activity. While you cannot hear conversations in this mode, it is
an excellent way to determine which talk group IDs are the most active. To set the scanner
to monitor IDs, hold down SRCH until you hear two short beeps, and SRCH begins to flashing.
All active group IDs appear in quick succession.
To stop monitoring IDs, press again.
Note: When you monitor IDs, any IDs you have locked out also appear.
USING TALK GROUP ID LISTS
When you program trunked frequencies into a bank (see “Storing Trunked Frequencies”
on Page XX), your scanner sets up ten scan lists for that one bank in which you
can store your favorite IDs. Each list can contain up to 10 IDs, for a total of 100 IDs
for each trunk scanning bank. If you use all the banks as trunking banks, you can store 1000 IDs.
Talk group ID lists help you to organize trunking system users into categories. For example,
you might use List 1 for police IDs, List 2 for fire department IDs, List 3 for
emergency medical service IDs, and so on. Once you store all the IDs in a list, you can scan them
just as you scan conventional channels. You can program IDs into
talk group ID lists manually, during a search, or automatically.
Manually Storing Talk Group IDs in Talk Group ID Lists
1. Select the trunking programming mode and the bank you want to change.
2. Use or to choose trunk system, and press E/PGM.
3. Use or tto choose Prog id, and press E/PGM.
4. Press or t to select the scan list location.
5. Enter the talk group IDs for each trunk system.

2. Press ./CLR to enter the dash.
3. Enter the fleet number.
4. Press E/PGM.
Note: Remember the AFS format allows you to enter full or partial EDACS IDs for powerful flexibility in all
modes. Be sure to read the section “An EDACS Trunked System” to learn how this works.
The scanner defaults to AFS talk group displays for EDACS only.
Entering EDACS Partial Talk Groups
You can enter partial group numbers in an EDACS talk group. By entering only the desired portion of a group,
you can select either 128, 8, or 1 talk group. For example, you might program every talk group in a police
department by pressing just four keys.
Note: You cannot use partial talk groups in decimal mode. (See “Selecting the EDACS Talk Group ID Format”
on Page XX.)
You can program a specific talk group such as 01-011 into the scan list memory. In AFS mode, you can
program the talk groups for an entire agency by pressing corresponding keys.
For example:
You Press To Scan
01 . E all 01 groups
01 . 01 E all 01 talk groups within
the 01 agency
To enter a Partial EDACS ID:
1. Enter the agency number you want to store. Press ・/CLR /DELAY to enter the dash。

Remember the AFS format allows you to enter full or partial EDACS IDs for powerful flexibility
in all modes. Be sure to read the section. An EDACS Trunked System to learn how this works.
The scanner defaults to “AFS talk group displays for EDACS only.
LTR talk groups
To enter an LTR ID:
For a LTR ID, the area code, home repeater number and
ID make up the talk group ID. See “LTR Tracking for more information.
1. Enter the area code.
2. Enter the home repeater number.
3. Enter the ID you want to store.
4. Press E/PGM.
Note: To clear a stored ID while entering an ID, press 0 and E successively, and start over.
Scanning the Talk Group ID Lists
Press SCAN/MANUAL to begin scanning the lists you have stored.
Note: If one or more of the IDs you stored are incorrect, Error flashes twice
and the scanner beeps several times, then the scan list numbers appear at the top of the
display. To correct the entry, delete at least one of the incorrect
IDs (see “Deleting a Stored Talk Group ID List”).
To remove a scan list from active scanning, use the number keys to enter the scan
list’s number. The scan list number turns off, and the IDs in that list are not scanned.
Note: One of the ten scan lists must always be active. You cannot remove all of them.
To restore a scan list to active scanning, use the number keys to enter the number of the list again.
Press SRCH to return to the previously selected function.
Priority Talk Group ID Scanning
You can assign a priority to a favorite ID so during scanning the scanner checks that ID
more frequently than the others in the list. Each of the ten memory locations reserved for
storing lists (see “Using Talk Group ID Lists” on Page XX) can have only one priority ID,
and the ID assigned that priority in List 1 has the highest priority of all.
To assign a priority to an ID, press and hold PRI. P appears.
To turn priority ID scanning on or off, repeatedly press PRI during ID scanning or manual operation.
PRI appears when priority scanning is turned on.
Note: Priority ID scanning does not operate when priority IDs are locked out.
See “Locking Out Talk Group IDs” on Page XX.
SCANNING TYPE I AND HYBRID TRUNKED SYSTEMS
Your scanner is preset to scan Type II system IDs. When you scan trunked frequencies, each Type II user ID
you see appears as an even number without a dash (example 2160). Your scanner can also scan Type I
trunked systems. Each Type I ID appears as a three- or four-digit number, followed by a hyphen, followed by a
one- or two-digit number (example 200-14).
If you notice a mix of odd- and even-user IDs (examples 6477, 2160, 6481, 6144, and 1167), then you are
probably monitoring either a Type I or hybrid (a combination of Type I and Type II user IDs) system with the
S-Bit function turned off (see “Types of Trunking Systems” on Page XX and “Turning the Status Bit Ignore
(S-Bit) On or Off” on Page XX).
Subfleet information is included with the frequency list for a Type I system. To enter the
provided map, see “Programming a Fleet Map” on Page XX.
Note: To locate suitable fleet map information, review the contents of website www.trunkscanner.com.
If you do not already know the size codes used, you will have to guess. Since you do not have to
figure out all the blocks at one time, this is not as hard as it might seem.
Select a size code for a block, then press SRCH and listen to the conversations. If you are
receiving most of the replies, then you have probably selected the right size
code and can program the next block of the map. There are 16 preset fleet maps to choose from,
and it is best to start with these when setting up a Type I or hybrid trunk scanning bank.
If none of the following preset fleet maps allow you to follow complete conversations, then you
probably need to program your own fleet map (see “Programming a Fleet Map” on Page XX).

Note: When the scanner searches for transmissions, you see Type I fleet and subfleet IDs
such as 100-12, 100-9, 000-12, or 400-8.
How do you know if the preset map you selected is correct?
Listen to find out if you are following complete conversations. If not, try another preset map.
Programming a Fleet Map
1. Select the trunking programming mode and the bank you want to change.
2. Repeatedly press or to select Type 1 System (E1), then press E/PGM.
3. Repeatedly press or to select FLEEt, then press E/PGM.
A preprogrammed fleet map appears.
4. Repeatedly press or until USr appears. Then press E/PGM.
5. Repeatedly press or to select the size code for the first block, then press E/PGM. The next
available block appears.
6. Repeat Step 5 until you have selected a size code for each desired block.
7. Press SRCH. The scanner exits the trunking programming mode, tunes the data channel,
then searches using the map you programmed.
Note: If you select size code S-12, S-13, or S-14, these restrictions apply:
• S-12 can only be assigned to Blocks 0, 2, 4, or 6
• S-13 can only be assigned to Blocks 0 and 4
• S-14 can only be assigned to Block 0
Since these size codes require multiple blocks, you will be prompted for the next available block
when you program a fleet map. For example, if you assign Block 0 as S-12, the scanner prompts you
for b2, the next block available, instead of b1. If you assign Block 0 as S-14, you would not see
another prompt because S-14 uses all available blocks.
Programming the Base and Offset Frequencies
To properly track Motorola VHF and UHF trunked systems,
you must program the applicable base and offset frequencies for each system.

A hybrid system is simply a Type I system with some of its blocks designated as Type II blocks.
To program a hybrid system, follow the steps listed in “Programming a Fleet Map” on Page XX.
However, if you want a block to be Type II, instead of pressing or to select the
size block (Step 7), enter size code S-0 instead.
Turning On/Off the Motorola Disconnect Tone Detect Function
When this function is disabled, the radio looks for squelch before returning to the control channel
instead of waiting for the disconnect tone. Only in rare instances will you need to adjust the default settings. The
condition to return to control channels depends on whether the signal is present or not.
