FEATURES
Your new 0712 200 Channel VHF/Air/UHF Desktop Scanner lets you scan conventional transmissions,
and is preprogrammed with search banks for convenience. By pressing a one touch search key, 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 22,000 exciting frequencies, including those used by
police and fire departments, ambulance services, aircraft, and amateur radio services, and you can
change your selection at any time.
Your scanner also has these special features:
Spectrum Sweeper – a powerful new tool for you to rapidly detect, monitor and store frequencies for
Page 2
0712 Owner’s Manual
nearby radio transmissions.
One Touch Search Banks — let you search preset frequencies in separate marine, fire/police, aircraft,
ham, and weather banks, to make it easy to locate specific types of calls.
Display Backlight — makes the scanner easy to read in low-light situations.
Lockout Function — lets you set your scanner to skip over specified channels or frequencies when
scanning or searching.
Ten Channel-Storage Banks — you can store 20 channels in each bank (200 total channels), letting you
group channels so you can more easily identify calls.
Tune — lets you tune for new and unlisted frequencies starting from a specified frequency.
SAME/FIPS Weather Alert — displays the weather event for the specific cities or counties you choose
so you can hear the alert tone.
Memory Backup — keeps the frequencies stored in memory for an extended time during a power loss.
Scan Delay — delays scanning for about 2 seconds before moving to another channel, so you can hear
more replies that are transmitted on the same channel.
Priority Channel — lets you program a channel as the priority channel. As the scanner scans, it checks
the priority channel every 2 seconds so you do not miss transmissions on that channel.
Data Cloning — lets you transfer the programmed data to another 0712 scanner.
Liquid-Crystal Display — makes it easy to view and change programming information.
Supplied Telescoping Antenna — provides good reception of strong local signals.
External Antenna Connector — lets you connect an external antenna (not supplied) with a BNC

THE FCC WANTS YOU TO KNOW
This equipment has been tested and found to comply with the limits for a scanning receiver, pursuant to
Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful
interference in a residential installation. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance with the instructions, may cause harmful
interference to radio communications.
However, there is no guarantee that interference will not occur in a particular installation. If this
equipment does cause harmful interference to radio or television reception, which can be determined by
turning the equipment off and on, the user is encouraged to try to correct the interference by one or
more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
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
Page 4
0712 Owner’s Manual
• 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

PREPARATION
POWER SOURCES
USING AC POWER
You can power the scanner using a supplied AC adaptor.
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 positive and its plug must fit the scanner's PWR DC 9V jack. Using an adaptor that does
not meet these specifications could damage the scanner or the adapter.
• Always connect the AC adaptor to the scanner before you connect it to AC power. When you finish,
disconnect the adaptor from AC power before you disconnect it from the scanner.
• The correct orientation for the enclosed power adaptor is in a vertical or floor-mount position.
To power the scanner using an AC adaptor, connect the plug into the scanner’s DC 9V jack. Then
connect the AC adaptor to a standard AC outlet.
WARNING: To prevent electric shock, do not use the AC adaptor’s polarized plug with an extension cord,
receptacle, or other outlet unless you can fully insert the blades to prevent blade exposure.
Page 5
0712 Owner’s Manual
USING VEHICLE BATTERY POWER
You can power the scanner from a vehicle’s 12V power source (such as cigarette-lighter socket) using a
9V, 400-mA DC adaptor with 4.75mm outer/1.7mm inner plug. Its center tip must be set to positive and
its plug must fit the scanner's DC 9V jack. Using an adapter that does not meet these specifications
could damage the scanner or the adaptor.
Cautions: 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.
To power the scanner using a DC adaptor, connect the plug into the scanner’s DC 9V jack. Plug the
other end of the DC adaptor into your vehicle’s cigarette-lighter socket.
Note: If you use a cigarette-lighter power cable and your vehicle’s engine is running, you might hear
electrical noise from the engine while scanning. This is normal.
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.
Frequency Antenna Length
29-174 MHz Extend fully
380-512 MHz Extend 2 segments
Connecting an Outdoor 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.
Always use 50 Ohm coaxial cable, such as RG-58 or RG-8, to connect an outdoor antenna. For lengths
Page 6
0712 Owner’s Manual
over 50 feet, use RG-8 low-loss dielectric coaxial cable. If the antenna cable’s connector does not have
a BNC connector, you will also need a BNC adapter.
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 you installing or removing an outdoor antenna. If the antenna starts
to fall, let it go! It could contact overhead power lines. If the antenna touches a power line, contact with
the antenna, mast, cable, or guy wires can cause electrocution and death. Call the power company to
remove the antenna. DO NOT attempt to do so yourself.
CONNECTING AN EARPHONE/HEADPHONES
For private listening, you can plug an 1/8 -inch (3.5-mm) mini-plug earphone or headphones (not
supplied), into the (headphone symbol mark) jack on the back of the scanner. This automatically
disconnects the internal speaker.
Listening Safely
To protect your hearing, follow these guidelines when you use an earphone or headphones.
• Set the volume to the lowest setting before you begin listening. After you begin listening, adjust the
volume to a comfortable level.
• Do not listen at extremely high volume levels. Extended high-volume listening can lead to permanent
hearing loss.
• 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 wear an earphone or headphones with your scanner when operating a motor vehicle or riding a
bicycle 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 while riding a bicycle, be very careful. Do not
listen to a continuous broadcast. Even though some earphones and headphones let you hear some
outside sounds when you listen at normal levels, they still can present a traffic hazard.
CONNECTING AN EXTENSION SPEAKER
Page 7
0712 Owner’s Manual
In a noisy area, an extension speaker (not supplied) might provide more comfortable listening. Plug the
speaker cable’s 1/8 inch (3.5 mm) mini-plug into your scanner’s (headphone symbol mark) jack.
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 or tune function.
You can also search the One Touch 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 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
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 (1 to 10) of 20 channels each, a total of 200 channels. You can use each
channel-storage bank to group frequencies, such as those used by the police department, fire
department, ambulance services, or aircraft.
Page 10
0712 Owner’s Manual
For example, a 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).
One Touch Banks
The scanner is preprogrammed with the frequencies allocated by marine, fire/police, aircraft, ham radio,
and weather services. This is handy for quickly finding active frequencies instead of searching through
an entire band (see “Searching the One Touch Banks” on Page XX).
Note: The frequencies in the scanner’s service banks are preset. You cannot change them.

under the bank’s number.
Notes:
• You cannot turn off all banks. There 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 a bank during scanning, the scanner moves to the selected bank and scans it.
If no transmission is found, the scanner continues scanning to scan through all selected banks.
MONITORING A STORED CHANNEL
You can continuously monitor a specific channel without scanning. This is useful if you hear an
emergency transmission 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. Pressing SCAN/MAN until MAN appears.
2. Enter the channel number (1–200).
3. Press SCAN/MAN 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. Pressing SCAN/MAN to stop scanning.
2. To select the desired channel number, use the number keys to enter that channel number (1–200).
Page 18
0712 Owner’s Manual
3. Press PGM. PGM appears.
4. Press 0 then ENT. The frequency number changes to 000.0000 to indicate the channel is cleared.
5. To clear another channel, use the number keys to enter that channel number (1–200), then press
PGM again. Or, repeatedly press PGM until the desired channel number appears. Then repeat Step 4.
LISTENING TO THE MARINE BANK
To listen to the marine bank, press MAR. MAr appears about 2 seconds, then the scanner starts
searching from marine channel 16.
To stop searching the channels, press PSE. SRCH disappears and MAN appears.
To change the channel manually, press ^ or v.
To search through the marine bank again, press PSE. MAN disappears and SRCH appears To change
the searching direction, press ^ or v.
You can select a marine channel directly. When the scanner stops scanning the marine bank, use the
number keys to enter the two-digit channel number.
Note: While Marine band search, lock out functions. See “Locking Out Marine and WX Channels” on
Page XX.
LISTENING TO THE WEATHER BAND
The FCC (Federal Communications Commission) has allocated channels for use by the National
Oceanic and Atmospheric Administration (NOAA). Regulatory agencies in other countries have also
allocated channels for use by their weather reporting authorities.
NOAA and your local weather reporting authority broadcast your local forecast and regional weather
information on one or more of these channels.
Listening to a Weather Channel
To hear your local forecast and regional weather information, press WX. WEAthEr appears for about 2
Page 19
0712 Owner’s Manual
seconds, then the scanner starts searching the weather bank.
To stop searching the channels, press PSE. SRCH disappears and MAN appears.
To change the channel manually, press ^ or v.
To search through the weather bank again, press PSE. MAN disappears and SRCH appears. To
change the searching direction, press ^ or v.
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 7 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.
2. Press PGM to access the FIPS code entry table.
3. Use ^ or v keys to select the desired FIPS code storage location.
4. Use the number keys to enter the desired FIPS code, and then press ENT to store the code. 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.
6. Press WX to exit the FIPS code entry table.
Notes:
• Your scanner can also detect the 1050 Hz weather alert tone when a weather channel is set as the
priority channel and weather priority operation is enabled (see “Priority”). In this mode all alerts are
received. FIPS settings are ignored.
Page 20
0712 Owner’s Manual
• The scanner sounds an alert or beep when it receives the SAME code. If you do not stop the alert (or
beep) for five minutes, the alert stops and the scanner beeps every ten seconds. If the scanner receives
a new message after five minutes, it sounds the alert or beep. To stop the sound and ready the scanner
to receive a new alert signal before the five minute time out, press any key.
7. Press PRI/ALERT to initiate SAME standby. The scanner will monitor the all weather radio station for
alerts with FIPS codes that match the codes you entered in the FIPS entry table. To exit SAME standby,
press PRI/ALERT again.
Skywarn
Many areas of the country have amateur radio repeaters that have been designated as “Skywarn”
repeaters. During times of severe weather, these repeaters are used to relay reports of severe weather
directly to meteorologists at a local National Weather Service (NWS) forecast office. Using the Skywarn
feature in your scanner, you can easily jump to Skywarn repeater frequencies and monitor these reports,
in many cases hearing about severe weather in your area instantly as it occurs.
This function lets you quickly move to the skywarn channels (Channel 200) from any mode by pressing
and holding WX about 2 seconds. The scanner displays SKYWARN symbol.
Note: To activate this function, you must program your desired Skywarn frequency into the Skywarn
channel.
Spectrum Sweeper
Your scanner’s Spectrum Sweeper feature provides a powerful new tool for you to rapidly detect,
monitor and store frequencies for nearby radio transmissions. The Spectrum Sweeper feature is similar
in functionality to portable frequency counters that cost much more than your scanner, but provides
many advantages over typical portable frequency counters. For example:
The Spectrum Sweeper allows you to sweep the entire range of your scanner’s design frequencies, or
you can specify those frequency ranges that you wish to sweep and exclude ranges that you do not
want to sweep. This allows you to omit frequency ranges with constant strong frequency activity, such
as those with paging or broadcast transmitters. Many portable frequency counters will remain locked to
a nearby constant signal, such as a paging or broadcast transmitter, and will not function properly until
you have left the vicinity of the transmitter.
The Spectrum Sweeper feature is more sensitive than portable frequency counters and will detect
Page 21
0712 Owner’s Manual
transmissions at a greater distance. You can activate the Attenuator to reduce the sensitivity if desired.
Once an active frequency is found, the transmission is played through your scanner’s speaker, and you
can quickly store it in any of your scanner’s memory locations.
Using Spectrum Sweeper
The Spectrum Sweeper can be set to watch for activity on all band, Police/Fire, Aircraft, or Ham
frequencies. When the scanner is in manual, scan or tune mode, press SS to watch for activity on all
band. When the scanner is in Police/Fire search band, press SS to watch for activity on Police/Fire band.
When the scanner is in Aircraft band, press SS to watch for activity on Aircraft band. When the scanner
is in Ham band, press SS to watch for activity on Ham band.
You can also turn on/off frequency sub-bands using the corresponding number keys while Spectrum
Sweeper is active.
Note: Priority mode is not available while using the Spectrum Sweeper.
SPECIAL FEATURES
DELAY
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 a channel or frequency with a programmed delay, DLY appears and the
scanner continues to monitor that channel or frequency for 2 seconds after the transmission stops
before resuming scanning, searching, tuning, or spectrum sweeping.
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 resumes
scanning.
• If the desired channel is not selected, manually select the channel, then press DELAY/• .
• If the scanner is searching, tuning, or spectrum sweeping, 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 2-second delay in a channel or for all frequency, press DELAY /• while the scanner is
monitoring that channel or frequency. DLY disappears.

0712 Owner’s Manual
LOCKING OUT CHANNELS OR FREQUENCIES
You can increase the effective scanning or search speed by locking out individual channels or
frequencies that have a continuous transmission, such as a weather channel (see “National Weather
Frequencies” on Page XX) or a birdie frequency (see “Birdie Frequencies” on Page XX).
Locking Out Channels
To lock out a channel during scanning, press L/O/L/O RVW when the scanner stops on the channel.
To manually lock out a channel, select the channel then press L/O/L/O RVW until L/O appears.
To remove the lockout from a channel, manually select that channel again, then press L/O/L/O RVW
until L/O disappears.
Notes:
• Your scanner automatically locks out empty channels.
• You can still manually select locked-out channels.
Locking Out Marine and WX Channels
To lock out a Marine or WX channel during searching, press L/O when the scanner stops on the
channel.
To manually lock out a Marine or WX channel, select the channel then press L/OUT.
To remove the lockout from a Marine or WX channel, manually select that channel again, then press
L/O until L/O disappears.
Locking Out Frequencies
To lock out a frequency during a one touch search or spectrum sweeper, press L/O/L/O RVW when the
scanner stops on that frequency. The scanner locks out the frequency then continues
searching/sweeping.
Notes:
• You can lock out as many as 50 frequencies during a search (or spectrum sweep). If you try to lock out
Page 23
0712 Owner’s Manual
more, FLo -FULL appears (see “Reviewing Locked-Out Frequencies” and “Removing Lockouts From All
Frequencies”).
• The scanner uses same Lockout List between one touch search bank and spectrum sweeper. (ex.: the
scanner uses same lock out list between aircraft search band and aircraft spectrum sweeper band.)
Reviewing Locked-Out Frequencies
To review the frequencies you locked out, hold down L/O/L/O RVW for about 2 seconds during a search
or spectrum sweeper, then repeatedly press ^ or v. L-r (Lockout Review) appears and the scanner
displays all locked out frequencies as you press ^ or v, or, EMPty appears when the search bank has no
locked out frequencies. When you reach the highest locked-out frequency, the scanner beeps twice and
returns to the lowest locked-out frequency.
Removing Lockouts Form All Frequencies in a One Touch Search Bank
Note: These steps do not clear any lockouts in the marine and weather bank.
1. Hold down L/O/L/O RVW for about 2 seconds during a desired search band. L-r appears.
2. While holding down TUNE/CLEAR, press L/O to clear the lockout. FLo ALL-CL appears about 2
seconds. After 2 seconds, YES ---Ent and No ---CLEAr appears alternately.
3. Press ENT. L-r EMPty appears. The scanner clears any lockouts from all frequencies in a one touch
bank. Or, if you do not want to clear the lockouts, press TUNE/CLEAR.
USING PRIORITY
The priority feature lets you scan through channels and still not miss important or interesting calls on a
frequency you select. You can program one frequency into the priority channel. As the scanner scans, if
the priority feature is turned on, the scanner checks the priority channel for activity every 2 seconds.
1. Press PGM, then press PRI/ALERT. PCH and 000.0000 or the previously-stored frequency appear.
2. Enter the frequency you want to enter into the priority channel, then press ENT. The display flashes
twice.
To program a weather channel as the priority channel:
Page 24
0712 Owner’s Manual
1. Press WX.
2. Select the weather channel you want to program as the priority channel.
3. Press and hold ENT then PRI. P ChAnnEL is displayed momentarily. Aftter P ChAnnEL appears, PCH
flashes and 000.0000 or the previously-stored frequency appears.
4. Press ENT to store the priority channel and display blinks two times. Press CLEAR to cancel.
To turn on the priority feature, press PRI/ALERT during scanning or searching. PRI appears. The
scanner checks the priority channel every 2 seconds and stays on the channel if there is activity. PCH
and the frequency appear whenever the scanner is set to the priority channel.
To turn off the priority feature, press PRI/ALERT. PRI disappears.
Note: If you program a weather frequency into the priority channel and the scanner detects a WX alert
tone on that frequency (see “WX Alert” on Page XX), the scanner sounds the alert tone and ALErt
flashes. Press any key to turn off the alarm.
TURNING THE KEY TONE ON AND OFF
The scanner is preset to sound a tone each time you press one of its keys. You can turn the key tone off
or on.
1. If the scanner is on, slide POWER to off.
2. Slide POWER to turn on the scanner. Welcome message appears..
3. While Welcome message appears, press 1 to turn on the key tone or 2 to turn it off..
Cloning the Programmed Data
You can transfer the programmed data to and from another 0712 scanner using an optional connecting
cable with 3.5mm phone plugs on both ends (not supplied).
1. Turn on both scanner.
2. Connect the connecting cable to each scanner’s PC/IF jack. CLOnE and UP to SEnd appears.
Page 25
0712 Owner’s Manual
3. Press ^ at the host scanner.
4. SEndInG appears at the host scanner.
The scanner sends the data. To exit the clone mode, remove the cable.
CLOnE and Error may alternately appear when the scanner receives data from a scanner other than a
0712. If this happens when the scanner receives data from another 0712, turn off the scanner and then
turn it on again.
INITIALIZING THE SCANNER
If the scanner’s display locks up or does not work properly after you connect a power source, you might
need to initialize 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.
1. Turn off the scanner, then turn it on again. WELCOME SCAnnInG rECEIVEr appears.
2. Press 0 while welcome message appears. Then press 1. InItIAL appears about 2 seconds. After 2
seconds, YES ---Ent and No ---CLEAr appears alternately.
3. Press ENT. WAIt appears for about 2 seconds.
Note: Do not turn off the scanner until the initialization is complete. When the initialization is complete,
1CH 000.0000 appears on the display.
A GENERAL GUIDE TO SCANNING
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 cut out the birdie.
Page 26
0712 Owner’s Manual
To find the birdies in your individual 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 search every frequency range from its lowest frequency to the highest.
Occasionally, the searching will stop as if it had found a signal, often without any sound. That is a birdie.
Make a list of all the birdies in your scanner for future reference.
FREQUENCY CONVERSION
The tuning location of a station can be expressed in frequency (kHz or MHz) or in wavelength (meters).
The following information can help you make the necessary conversions.
1 MHz (million) = 1,000 kHz (thousand)
• To convert MHz to kHz, multiply the number of megahertz by 1,000:
30.62 (MHz) x 1000 = 30,620 kHz
• To convert from kHz to MHz, divide the number of kilohertz by 1,000:
127,800 (kHz) / 1000 = 127.8 MHz
• To convert MHz to meters, divide 300 by the number of megahertz:
300 / 50 MHz = 6 meters
FAQs (Frequently Asked Questions)
The scanner is not working at all. What’s wrong?
• The AC or DC adaptor might not be connected. Be sure the adaptor’s barrel plug is fully inserted into
the DC 9V jack. The center tip of the adaptor’s barrel plug must be set to positive.
The scanner does not receive any stations or reception is poor. What’s wrong?
• The scanner might need to be initialized. Turn the scanner off then on again, or initialize the scanner
(see “Initializing the Scanner”).
The scanner is on but does not scan. What’s wrong?
• The squelch might not be adjusted correctly. Turn SQ clockwise. There might only be one channel or
no channels stored in the scanner. Store frequencies into more than one channel.
Page 27
0712 Owner’s Manual
While scanning, the scanner locks on frequencies that have an unclear transmission. What’s wrong?
• Some frequencies programmed into the scanner might be the same as “birdie” frequencies. Avoid
programming “Birdie Frequencies” or only listen to them manually.
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.
