2Introduction
ˆ
Introduction
Thank you for purchasing the RadioShack
200-Channel VHF/AIR/UHF Desktop
Scanner. This scanner gives you direct
access to over 25,000 frequencies, including
those used by police and fire departments,
ambulance services, government agencies,
air, and amateur radio services. You can
select up to 200 channels to scan, and you
can change your selection at any time.
The secret to your scanner's ability to scan
so many frequencies is its built-in
microprocessor. Your scanner also has
these special features:
Four Service Banks — let you search
preset frequencies in separate fire/police, air,
ham radio, and marine banks, to make it
easy to locate specific types of calls.
Two-Second Scan Delay — delays
scanning for 2 seconds before moving to
another channel, so you can hear more
replies.
Ten Channel-Storage Banks — let you
store up to 20 channels in each of 10
different banks, to group channels so you
can more easily identify calls.
20 Monitor Memories — let you temporarily
save up to 20 frequencies you locate during
a search, so you can move selected
frequencies to channel storage later.
Memory Backup — keeps the channel
frequencies stored in memory for about 1
hour during a power loss.
HyperSearch
TM and HyperScan
TM — let
you set the scanner to search at up to 50
steps per second and to scan at up to 25
channels per second, to help quickly find
interesting transmissions.
Duplicate Frequency Check —
automatically notifies you if you are about to
store a frequency you have already stored,
to help avoid wasting storage space.
Direct Search — lets you search for new
and unlisted frequencies starting from a
specified frequency.
Priority Channel — lets you program a
frequency in the priority channel to be
scanned every 2 seconds so you do not miss
important calls.
Weather Band (WX) Key — scans seven
preprogrammed weather frequencies tokeep
you informed about current weather
conditions.
Weather Alert — automatically sounds the
alarm tone to advise of hazardous weather
conditions when the scanner detects an alert
signal on the local NOAA weather channel.
Lock-Out Function — lets you set your
scanner to skip over specified channels or
frequencies when scanning or searching.
Liquid Crystal Display — makes it easy to
view and change programming information
at any time.
Display Backlight — makes the scanner
easy to read in low light situations.
Supplied Telescoping Antenna — lets the
scanner receive strong local signals.
External Antenna Terminal — lets you
connect an external antenna (not supplied)
to the scanner.

Introduction
Dual Conversion — helps prevent
interference from image frequencies.
Your scanner receives these frequencies
(MHz):
FCC NOTICE
Your scanner might cause TV or radio
interference even when it is operating
properly. To determine whether your scanner
is causing the interference, turn off your
scanner. If the interference goes away, your
scanner is causing it. Try to eliminate the
interference by:
• moving your scanner away from the
receiver
• connecting your scanner to an outlet
that is on a different electrical circuit
from the receiver
• contacting your local RadioShack store
for help
If you cannot eliminate the interference, the
FCC requires that you stop using your
scanner.
This device complies with Part 15 of the
FCC
Rules
. Operation is subject to the following
two conditions: (1) this device may not cause
harmful interference, and (2) this device
must accept any interference received,
including interference that may cause
undesired operation.
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), you are subject to fines
and possible imprisonment for intentionally

POWER SOURCES
Using AC Power
You can power the scanner using the
supplied 12V, 300mA AC adapter.
Cautions:
You must use a Class 2 power
source that supplies 12V DC
and delivers at least 300 mA.
Its center tip must be set to positive and
its plug must fit the scanner's DC12V
jack. The supplied adapter meets these
specifications. 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.
Warning: To prevent electric shock, do not
use the AC adapter’s polarized plug with an
extension cord, receptacle, or other outlet
unless you can fully insert the blades to
prevent blade exposure.
Follow these steps to power the scanner
from a standard AC outlet.
1. Insert the AC adapter’s barrel plug into
the DC12V jack on the back of the
scanner.
2. Plug the adapter into a standard 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 12V, 300-mA DC cord and a
size M Adaptaplug™ connector (neither
supplied). Both are available at your local
RadioShack store.
Cautions:
You must use a power cord
that can carry 12V DC and at
least 300 mA. Its center tip
must be set to positive and its plug must
fit the scanner's DC12V jack. Using an
cord that does not meet these
specifications could damage the
scanner or the cord.
• Always connect the DC cord to the
scanner before you connect it to the
power source. When you finish,
disconnect the cord from the power
source before you disconnect it from the
scanner.
Follow these steps to power the scanner
from a vehicle’s cigarette-lighter socket.
1. Connect the adaptaplug connector to
the DC cord so the tip reads positive (+).
2. Insert the DC cord’s barrel plug into the
DC12V jack on the back of the scanner.
!!

Preparation
3. Plug the cord into the vehicle’s
cigarette-lighter socket.
Notes:
• If you use a 12V DC cord and your
vehicle's engine is running, you might
hear electrical noise on the scanner
caused by the engine. This is normal.
• Mobile use of this scanner is unlawful or
requires a permit in some areas. Check
the laws in your area.
CONNECTING AN ANTENNA
Connecting the Supplied Antenna
You must install an antenna before you can
operate the scanner.
The supplied telescoping antenna helps your
scanner receive strong local signals. To
install the antenna, thread it clockwise into
the hole on top of the scanner.
The scanner's sensitivity depends on its
location and the antenna's length. For the
best reception of the transmissions you want
to hear, adjust the antenna's length
according to the chart below.
Connecting an Outdoor Antenna
Instead of the supplied antenna, you can
connect an outdoor base-station or mobile
antenna (neither supplied) to your scanner.
Your local RadioShack store sells a variety
of antennas. Choose the one that best meets
your needs.
When deciding on an outdoor antenna and
its location, consider these points:
• The antenna should be located as high
as possible.
• The antenna and antenna cable should
be as far as possible from sources of
electrical noise (appliances, other
radios, and so on).
• The antenna should be vertical for the
best performance.
To connect an optional base-station or
mobile antenna, first remove the supplied
antenna from the scanner. Always use 50
Ohm coaxial cable, such as RG-58 or RG-8,
to connect the base-station or mobile
antenna. For lengths over 50 feet, use RG-8
low-loss dielectric coaxial cable. If the
antenna cable's connector does not fit in the
ANT jack on the back of the scanner, you
might also need a PL-259-to-Motorola
antenna plug adapter. Your local
RadioShack store carries a wide variety of
coaxial antenna cable and connectors.
Once you choose an antenna, follow the
mounting instructions supplied with the
antenna. Then route the antenna's cable to
Frequency Antenna Length
29–174 MHz Extend fully
380–512 MHz Extend 2 segments

8Understanding Your Scanner
the scanner and connect the cable to the
ANT jack.
Warning: Use extreme caution when you
install or remove an outdoor antenna. If the
antenna starts to fall, let it go! It could contact
overhead power lines. If the antenna touches
a power line, contact with the antenna, mast,
cable, or guy wires can cause electrocution
and death. Call the power company to
remove the antenna. Do not attempt to do so
yourself.
Caution: Do not run the cable over sharp
edges or moving parts that might damage it.
ˆ
Understanding Your Scanner
Once you understand a few simple terms
used in this manual and familiarize yourself
with your scanner's features, you can put the
scanner to work for you. You simply
determine the type of communications you
want to receive, then set the scanner to scan
them.
A frequency is the tuning location of a
station (expressed in kHz or MHz). To find
active frequencies, you can use the search
function.
You can also search the service-search
banks, which are preset groups of
frequencies categorized by type of service.
When you find a frequency, you can store it
into a programmable memory location called
a channel, which is grouped with your other
channels in a channel-storage bank. You
can then scan the channel-storage banks to
see if there is activity on the frequencies
stored there. Each time the scanner finds an
active frequency, it stays on that channel
until the transmission ends.
A LOOK AT THE CONTROLS
Some of the scanner’s keys perform more than one function (such as MON/CL) and are

UNDERSTANDING SERVICE
BANKS/BANKS
Channel Storage Banks
To make it easier to identify and select the
channels you want to listen to, channels are
divided into 10 banks of 20 channels each.
Use each channel-storage bank to group
frequencies, such as those used by the
police department, fire department,
ambulance services, or aircraft (see “Guide
to the Action Bands” on Page 23). For
example, the police department might use
four frequencies, one for each side of town.
You could program the police frequencies
starting with Channel 1 (the first channel in
bank 1) and program the fire department
frequencies starting with Channel 21 (the
first channel in bank 2).

11
Understanding Your Scanner
Service Banks
The scanner is preprogrammed with the
frequencies allocated by fire/police, aircraft,
ham radio, and marine services. In these
service banks, you can search through the
frequencies and store them in channels for
fire/police, aircraft, ham radio, and marine
banks. This is handy for quickly finding active
frequencies instead of searching through an
entire band.
Note: The frequencies in the scanner's
service bank are preset. You cannot change
them.

STORING KNOWN
FREQUENCIES INTO
CHANNELS
Good references for active frequencies are
the RadioShack
Police Call
,
Aeronautical
Frequency Directory
, and
Maritime
Frequency Directory
. We update these
directories every year, so be sure to get a
current copy.
Follow these steps to store frequencies into
channels.
1. Press PGM, enter the channel number
(1–200) where you want to store a
frequency, then press PGM again. The
channel number appears.
2. Use the number keys and • to enter the
frequency (including the decimal point)
you want to store.
3. Press ENTER to store the frequency into
the channel.
Notes:
• If you made a mistake in Step 2,
Error appears and the scanner
beeps when you press ENTER.
Simply start again from Step 2.
• Your scanner automatically rounds
the entered frequency down to the
closest valid frequency. For example,
if you enter a frequency for 151.473,
your scanner accepts it as 151.470.
• If you entered a frequency that is
already stored in another channel,
the scanner beeps three times and
displays the lowest channel number
where the frequency is already
stored, and -dUPL- then the
frequency flashes. If you want to
store the frequency anyway, press
ENTER again. Press MON/CL to clear
the frequency.
• Press DELAY if you want the scanner
to pause 2 seconds on this channel
after a transmission ends before it
proceeds to the next channel (see
“Using the Delay Function” on
Page 20). The scanner also stores
this setting in the channel.

Operation
4. To program the next channel in
sequence, press PGM and repeat Steps
2 and 3.
FINDING AND STORING
ACTIVE FREQUENCIES
Searching the Service Banks
Your scanner contains groups of preset
frequencies called service banks. Each
service bank is associated with a specific
activity (see “Understanding Service Banks/
Banks” on Page 10). You can search for fire/
police, air, ham, and marine transmissions
even if you do not know the specific
frequencies that are used in your area. Then
you can store the frequencies you found into
the scanner's channels or monitor memories.
Note: You can use the scanner's delay
feature while searching the service banks
(see “Using the Delay Function” on
Page 20).
The following steps describe the operation of
the HAM, FD/PD, and AIR service banks. To
listen to the marine bank, see “Listening to
the Marine Bank” on Page 19.
1. Press BAND. The last selected band
name (such as HAM), SRCH, -b-, the
frequency and the group number (if any)
appear.
2. To select a different band, repeatedly
press BAND until the desired band name
appears on the display. After about 2
seconds, the scanner begins searching
rapidly up or down in that band for an
active frequency.
Notes:
• To search through the frequencies,
hold down 8

USING THE MONITOR
MEMORY
The scanner has 20 monitor memories that
you can use to temporarily store frequencies
while you decide whether to save them into
channels. This is handy for quickly storing an
active frequency when you are searching
through an entire band. You can store a
frequency into a monitor memory during a
service bank or direct search.
You can select monitor memories manually,
but you cannot scan them. See "Listening to
a Monitor Memory Frequency."

must be at least one active bank.
• You can manually select any channel in
a bank, even if the bank is turned off.
• When you turn on the bank while
scanning, the scanner moves to the
selected bank's first channel and
continues scanning.
MONITORING A STORED
CHANNEL
You can continuously monitor a specific
channel without scanning. This is useful if
you hear an emergency broadcast on a
channel and do not want to miss any details
— even though there might be periods of
silence — or if you simply want to monitor
that channel.
Follow these steps to manually select a
channel.
1. Press MANUAL.
2. Enter the channel number (1–200).
3. Press MANUAL again.
CLEARING A STORED
CHANNEL
If you no longer want a frequency stored in a
channel (and you do not want to replace that
frequency with a different one), follow these
steps to clear the stored frequency.
1. Press MANUAL to exit the service banks
or to stop scanning.
2. Use the number keys to select the
desired channel number, then press
MANUAL.
3. Press PGM. PGM appears.
4. Press 0, then press ENTER. The
frequency number changes to
000.0000 to indicate the channel is
cleared.

for about 2 seconds.
LISTENING TO THE
WEATHER BAND
The FCC (Federal Communications
Commission) has allocated seven
frequencies for use by the National Oceanic
and Atmospheric Administration (NOAA).
NOAA broadcasts your local forecast and
regional weather information on one or more
of these frequencies. We have programmed
your scanner with these seven frequencies.
To hear your local forecast and regional
weather information, press WX. The scanner
begins to scan the weather band.
You will probably receive one frequency
better than the others for your area. The
scanner should stop within a few seconds on
that frequency. If the broadcast is weak,
press WX again to resume scanning.

Using the Weather Alert
This scanner can receive NOAA weather
alert tone broadcasts in case of an
emergency. The weather alert tone sound
warns you of serious weather conditions.
To listen for an alert tone, press PRI/ALERT
while you are tuned to the weather channel.
ALErt appears. If the scanner detects a
weather alert, it sounds a tone. Press any
key to mute the tone. To cancel the alert
monitoring and return to the weather channel
standard broadcast, press PRI/ALERT again.

USING THE DELAY
FUNCTION
Many agencies use a two-way radio system
that has a period of several seconds
between a query and a reply. To avoid
missing a reply, you can program a 2–
second delay into any channel or frequency.
When your scanner stops on any channel or
frequency with a programmed delay, DLY
appears and the scanner continues to
monitor that frequency for an additional 2
seconds after the transmission stops before
resuming scanning or searching.
You can program a 2 second delay in any of
these ways:
• If the scanner is scanning and stops on
an active channel, quickly press DELAY
before it continues scanning.
• If the desired channel is not selected,
manually select the channel, then press
DELAY.
• If the scanner is searching, press
DELAY. DLY appears and the scanner
automatically adds a 2-second delay to
every transmission it stops on in that
band.
To turn off the delay, press DELAY while the
scanner is monitoring the channel or
frequency. DLY disappears.
LOCKING OUT CHANNELS
AND FREQUENCIES
You can increase the scanning or search
speed by locking out individual channels or
frequencies that have a continuous
transmission, such as a weather channel
(see the “Weather Channel Frequency
Chart” on Page 19) or birdie frequency (see
“Birdie Frequencies” on Page 22).
Locking Out Channels
To lock out a channel while scanning, press
and release L/O (L/O RVW) when the scanner
stops on the channel.
To lock out a channel manually, select the
channel then press and release L/O (L/O
RVW) until L/O appears.
To unlock a channel, manually select that
channel again, then press L/O (L/O RVW). L/
Odisappears from the display.
Notes:
• The scanner automatically locks out
empty channels.
• You can still manually tune to locked-out
channels.
Locking Out Frequencies
To lock out a frequency during a service
bank, or a direct search, press L/O (L/O RVW)
when the scanner stops on the frequency.
The scanner locks out the frequency then
continues searching. You can lock out
frequencies in both direct search and service
bank searches.
Note: You can lock out as many as 50
frequencies during a search. If you try to lock
out more, FLo -FULL appears (see
“Reviewing Locked-Out Frequencies” on
Page 21and “Removing All Locked-Out Tags
From Frequencies” on Page 21).
