           If you set a search range that crosses over into a range of 
           frequencies that the scanner cannot tune, the scanner searches 
           only up to the limit of tunable frequencies and returns to 
           the starting frequency. 
 
 
SCANNING THE CHANNELS 
 
To begin scanning channels or to start scanning again after monitoring 
a specific channel, press SCAN. 
 
The scanner scans through all channels (except those you have locked 
out) in the active banks). 
 
NOTES:  You must store frequencies into channels before the scanner can 
        scan them. 
 
        The scanner does not scan empty channels. 
 
        To change the scanning direction, press UP ARROW or DOWN ARROW. 
 
 
TURNING CHANNEL-STORAGE BANKS OFF AND ON 
 
To turn off banks while scanning, press the banks number key until the 
bar under the banks number disappears.  The scanner does not scan any 
of the channels within the banks you have turned off. 
 
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. 
 
To turn on banks while scanning, press the banks number key until a bar

    PROGRAM and repeat Steps 3 and 4. 
 
 
Moving Frequencies from Monitor Memories to a Bank 
 
Your scanner can move all the frequencies you have stored in monitor 
memories into a bank you specify. 
 
NOTES:  If there are more frequencies in the monitor memories than there 
        are empty channels in the bank you select, the scanner moves only 
        as many frequencies from the monitor memories as it has room 
        for in the bank. 
 
        The scanner moves monitor memory frequencies into channels even 
        if the same frequencies are already stored in other channels. 
 
1.  Press AUTO.  The bar under the current bank number flashes, and AUTO 
    and AC-XXCH appear (where XX is the number of available channels in 
    the current bank).  If the current bank id full, A-FULL appears. 
 
2.  Repeatedly press AUTO to select the channel-storage bank where you 
    want to store monitor memory frequencies. 
 
3.  Hold down ENTER, then press MONITOR.  The scanner moves all 
    frequencies stored in monitor memories into the bank. 
 
 
Moving Frequencies from Bank to Monitor Memories 
 
You can move all stored frequencies within a bank to monitor memories. 
This lets you quickly clear channels within a bank without losing the 
frequencies. 
 
IMPORTANT:  If you move frequencies from a bank to monitor memories, all 
            frequencies already in the monitor memories are replaced with 
            those frequencies and any empty channels from the bank. 
 
1.  Press AUTO.  AUTO appears. 
 
2.  Repeatedly press AUTO to select the channel-storage bank that has 
    the frequencies you want to move. 
 
3.  Hold down ENTER, then press DIRECT/..  The scanner automatically 
    moves all frequencies in channel within the bank to monitor memories. 
 
 
DELETING FREQUENCIES 
 
Deleting a Frequency from a Channel or Monitor Memory 
 
1.  Press PROGRAM. 
 
2.  Use the number keys to enter the channel or monitor number containing 
    the frequency you want to delete. 
 
3.  If you are deleting the frequency from a channel, press PROGRAM.  If  
						

							    you are deleting the frequency in a monitor memory, press MONITOR. 
 
4.  Press 0, then press ENTER.  The frequency is deleted. 
 
5.  To delete more frequencies, repeat Steps 2-4. 
 
 
Deleting Frequencies from All Channels Within a Bank 
 
You can delete the frequencies in all channels within a bank.  This lets 
you quickly delete all frequencies from a bank if, for example, you want 
to use the bank to store a different set of frequencies. 
 
1.  Press AUTO.  AUTO appears. 
 
2.  Repeatedly press AUTO to select the channel-storage bank that has the 
    frequencies you want to delete.

bank.  This lets you delete all the old or uninteresting frequencies in  
channels you have locked out. 
 
1.  Press AUTO.  AUTO appears. 
 
2.  Repeatedly press AUTO is select the channel-storage bank that has the 
    locked-out frequencies you want to delete. 
 
3.  Hold down ENTER, then press L/OUT. 
 
 
SORTING FREQUENCIES WITHIN A BANK 
 
You can sort the frequencies you have stored within a bank.  The scanner 
moves the frequencies into consecutive channels, either from the lowest 
to the highest frequency, or the highest to the lowest frequency.  This 
makes it easy for you to see the range of frequencies you found 
(during auto store for example). 
 
NOTES:  During frequency sort, the scanner moves the frequencies it finds 
        within the bank from higher channels to lower, empty channels. 
 
        If you turn the scanner off during frequency sort, the scanner 
        stays on until it saves the portion of the sort it completed. 
        Then it turns off. 
 
1.  Press AUTO.  AUTO appears. 
 
2.  Repeatedly press AUTO to select the channel-storage bank that has 
    the frequencies you want to sort. 
 
3.  Hold down ENTER, then press UP ARROW to sort channels from the lowest 
    to the highest frequency, or press DOWN ARROW to sort channels 
    from the highest to the lowest frequency.  As the scanner sorts the 
    frequencies, Sor. appears. 
 
  
						

							LISTENING TO MONITOR MEMORIES 
 
To listen to a monitor memory, press MANUAL, then press MONITOR.  The 
current monitor memory frequency appears, and NON and the channel number 
flash.  To select other monitor memories, use the number keys to enter

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 TV or radio 
 
  Connecting your scanner to an outlet that is on a different electrical 
  circuit from the TV or radio 
 
  Contacting your local Radio Shack store for help 
 
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 (either, cellular, cordless, or other private 
  means of telephone transmission) 
 
  Pager transmissions 
 
  Any scrambled or encrypted transmissions 
 
According to the Electronic Communications Privacy Act (ECPA), you are 
subject to fines and possible imprisonment for intentionally listening 
to, using, or divulging the contents of such a transmission unless you 
have the content of a party to the communication (unless such activity 
is otherwise illegal).  We encourage responsible, legal scanner use. 
 
This scanner is primarily designed for use in the home as a base station. 
You can place it on a desk, shelf, or table. 
 
Your scanners front feet fold up or down.  Adjust them to give you the 
best view of the display. 
 
  
						

							POWER SOURCES 
 
You can power your scanner from either of these sources: 
 
  Standard AC power 
 
  Vehicle battery power using an optional DC cigarette-lighter power 
  cord 
 
NOTE:  If the scanner stops working properly after connecting it to power, 
       try resetting it. 
 
       The memory backup circuit begins to function a few minutes after 
       you supply power to the scanner.  How long the scanner will 
       maintain channels stored in memory depends on how long power has 
       been supplied to the scanner.  If power is continuously supplied 
       to the scanner for at least 4 days, the memory backup circuit 
       maintains the channels stored in memory for up to 3 months. 
 
 
Using Standard AC Power 
 
Plug the scanners power cord into a standard AC outlet. 
 
WARNING:  Do not use the scanners polarized plug with an extension cord, 
          receptacle, or other outlet unless the blades can be fully 
          inserted to prevent blades can be fully inserted to prevent 
          blade exposure. 
 
 
Using Vehicle Battery Power 
 
If your AC power does not work in an emergency, you can power your scanner 
from your vehicles cigarette-lighter socket with an optional DC 
cigarette-lighter power cord such as Cat. No. 270-1533 (not supplied). 
 
To connect an optional DC cigarette-lighter power cord, insert its barrel 
plug into the DC 13.8V jack on the back of the scanner, then plug the 
power cord into your vehicles cigarette-lighter socket. 
 
Cautions: 
 
   If you use a DC cigarette-lighter power cord with the scanner, it must 
   supply at least 1 amp of vehicle power.  Its center tip must be set to 
   positive, and its plug must correctly fit the DC 13.8 V jack on the 
   back of the scanner.  The recommended power cord meets these  
   specifications.  Using a power cord that does not meet these 
   specifications could damage the scanner or the power cord. 
 
   To protect your vehicles electrical system, always plug the power cord 
   into the scanner before you plug it into your vehicles cigarette-
lighter 
   socket.  Always unplug the power cord from the vehicles  
   cigarette-lighter socket before you unplug it from the scanner. 
 
Notes: 
 
   Mobile use of this scanner is unlawful or requires a permit in some 
   areas.  Check the laws in your area. 
 
   If the scanner does not operate properly when you connect a DC power  
						

							   cord, unplug the power cord from the cigarette-lighter socket and clean 
   the socket to remove ashes and other debris. 
 
CONNECTING THE ANTENNA 
 
The supplied telescoping antenna helps your scanner receive strong local 
signals.  To install the antenna, screw it clockwise into the hole on the 
scanners top. 
 
The scanners sensitivity depends on the antennas length and various 
environmental conditions.  For the best reception of the transmissions you 
want to hear, adjust the antennas length. 
 
Frequency                    Antenna Length 
 
29-174 MHz                   Extend Fully 
 
380-512 MHz                  Extend 2 segments 
 
806-960 MHz                  Collapse fully (1 segment only) 
 
Connecting an Optional Antenna 
 
The ANT jack on the back of the scanner makes it easy to use the scanner 
with a variety of antennas.  Instead of the supplied antenna, you can 
attach a different one, such as an external mobile antenna or outdoor base 
station antenna.  Your local RadioShack store sells a variety of antennas. 
 
When deciding on an antenna and its location, consider the following: 
 
   The location of the antenna should be 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. 
 
Always use 50-ohm coaxial cable, such as RG-58 or RG-8, to connect an 
outdoor antenna.  For lengths over 50 feet, use RG-8 low-loss dielectric 
coaxial cable.  If the coaxial cables connector does not fit in the ANT 
jack, you might also need a PL-259-to-BNC antenna plug adapter, such as 
Cat. No. 278-120.  Your local RadioShack store carries a wide variety of 
coaxial antenna cable and connectors. 
 
Follow the installation instructions supplied with the antenna, route the 
antenna cable to the scanner, then connect it to the ANT BNC-type jack on 
the back of the scanner. 
 
Warning:  Use extreme caution when installing or removing an outdoor  
          antenna.  If the antenna starts to fall, let it go.  It could 
          contact overhead power lines.  If the antenna touches a power  
          line, 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 objects. 
 
CONNECTING AN EARPHONE/HEADPHONES 
 
For private listening, you can plug an earphone or mono headphones (such 
as Cat. No. 33-175 or 20-210) into the headphones jack on the front 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 mot use an earphone of 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 while operating 
a motor vehicle, 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 extension speaker (Cat. No. 21-549) or an amplified 
speaker (Cat. No. 21-541) might provide more comfortable listening. 
 
Plug the speaker cables 1/8-inch mini-plug into the EXT SPKR jack on the 
back of your scanner. 
 
 
UNDERSTANDING YOUR SCANNER 
 
Once you understand a few simple terms we use in this manual and 
familiarize yourself with your scanners features, you can put the 
scanner to work for you.  You simply determine the communications you 
want to receive, then set the scanner to scan those frequencies. 
 
A frequency is the turning location of a station (expressed in kHz or 
MHz).  To find active frequencies, you can use the search function to 
search bands, which are preset ranges of frequencies. 
 
When you find a frequency, you can store it into a permanent 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. 
 
Another option is to store the frequency into a temporary memory location 
called a monitor memory until you decide to move it to a channel.  
						

							 
Just keep in mind - you search frequencies and scan channels.
