MOUNTING THE SCANNER

Using the Scanner as a Base Station

You can place this scanner on a desk, shelf, or table, to use it as a base
station.

Your Scanner's front feet fold up or down.  Adjust them to give you the
best view of the display.

Mounting The Scanner In Your Vehicle

If you use this scanner in a vehicle, mount it securely to avoid damage to
the scanner or vehicle or injury to anyone in the vehicle during sudden
starts or stops.

NOTES:  Mobile use of this scanner is unlawful or requires a permit in some
        areas.  Check the laws in your area.

        To mount the scanner in your vehicle, you need a mounting bracket
        and hardware such as Cat. No. (CMC) 20-0028 (not supplied), and a
        DC cigarette-lighter power cable such as Cat. No. 270-1533 (not
        supplied).

When you choose a mounting location, be sure:

    You can easily reach the scanner.

    All wires and cables will reach their connection points.

    Wires and cables will not interfere with the vehicle's pedals or other
    moving parts.

    The scanner is not directly in front of any heating vents.

CAUTION:  The scanner is designed to work in a vehicle that has a 12-volt,
          negative-ground electrical system.  Most vehicles have this type
          of system.  If you are not sure about your vehicle, check with
          your vehicle's dealer.

Follow these steps to mount the scanner in your vehicle.

1.  Choose a mounting location, then use the mounting bracket as a template
    to mark the positions for the mounting screw holes.

2.  In the marked locations, drill holes slightly smaller than the supplied
    screws.  Take care not to drill into or damage objects behind the 
    mounting surface.

3.  Attach the mounting bracket to the mounting location using the supplied
    self-tapping screws and lock washers.

4.  Attach the scanner to the mounting bracket using the supplied mounting
    knobs.

CONNECTING AN ANTENNA

The supplied telescoping antenna helps your scanner receive strong local
signals.

Follow these steps to install the supplied antenna.

1.  Hold the antenna so it stands straight up.

2.  Gently push the antenna's plug onto the ANT. jack on the scanner's back
    panel.

The scanner's sensitivity depends on the antenna's length and various
environmental conditions.  For the best reception of the transmissions you
want to hear, adjust the antenna's length.

  Frequency          Antenna Length
____________________________________________
 29-108 MHz          Extend fully
____________________________________________
108-174 MHz          Extend three segments
____________________________________________
174-512 MHz          Extend two segments
____________________________________________
512-956 MHz          Collapse all segments
____________________________________________

Instead of the supplied antenna, you can connect an outdoor base antenna or
external mobile antenna (not supplied) to your scanner.  Your local Radio
Shack store sells a variety of antennas.  Choose the one that best meets 
your needs.

When deciding on an outdoor base or external mobile 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.

To connect an optional antenna, always use 50-Ohm coaxial cable, such as
RG-58 or RG-8. For lengths over 50 feet, use RG-8 low-loss dielectric 
coaxial cable.  Your local Radio Shack store carries a wide variety of 
coaxial antenna cable.  If the coaxial cable's 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.

Follow the mounting instructions supplied with the antenna.  Then route the
antenna cable to the scanner, and connect it to the ANT.jack on the back of
the scanner.

CAUTION:  Do not run the cable over sharp edges or moving objects.

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.

CONNECTING POWER

You can power your scanner from either of the following sources:

    Standard AC power (with the supplied AC adapter).

    Your vehicle's battery (using an optional DC cigarette lighter power
    cable, Cat. No. 270-1533).

Memory Backup

When you first power the scanner, the scanner displays MEMO LOSS until you
program it.  After you program the scanner, MEMO LOSS disappears.

During a power loss, the memory backup circuit maintains the channels
stored in memory for up to 3 days.  If the memory backup circuit becomes
too weak to save the scanner's programming, the scanner displays MEMO LOSS
again when power is reapplied until you reprogram the scanner.

Using the Supplied AC Adapter

CAUTIONS:  Use only the supplied AC adapter.  Using a different adapter can
           damage your scanner and could present a safety hazard.

           To prevent electric shock, the plug's blades are polarized and
           fit only one way.  If the plug does not fit easily, turn it over
           and try again.  Do not force the adapter plug into the AC
           outlet.

           Always unplug the AC adapter from the AC outlet before you
           unplug its  barrel plug from the scanner.

Insert the AC adapter's barrel plug into the DC13.8V jack on the back of
the scanner, then plug the AC adapter into a standard AC outlet.

Using Your Vehicle's Battery Power

You can power your scanner from you vehicle's battery with an optional DC
cigarette lighter power cable such as Cat. No. 270-1533(not supplied).

CAUTIONS:  The scanner is designed to work in a vehicle that has a 12-volt,
           negative-ground electrical system.  Most vehicles have this type
           of system.  If you are not sure about your vehicle, check with
           your vehicle's dealer.

           If you use a DC cigarette lighter power cable with the scanner,
           it must supply 12 volts and deliver at least 500 milliamps.  Its
           center tip must be set to positive, and its plug must correctly
           fit the DC13.8V jack on the back of the scanner.  The
           recommended power cable meets these specifications.  Using a
           power cable that does not meet these specifications could
           seriously damage the scanner or the power cable.

To connect an optional DC cigarette lighter power cable, insert its barrel
plug into the DC13.8V jack on the back of the scanner, then plug the power
cable into your vehicle's cigarette lighter socket.

CAUTIONS:  Unplug the power cable from your vehicle's cigarette lighter
           socket when you turn off the ignition.  This prevents vehicle
           battery drain if you leave the scanner on when you turn off the
           ignition.

           Always unplug the power cable from your vehicle's cigarette
           lighter socket before you unplug its barrel plug from the
           scanner.

NOTE:  If the scanner does not operate when you turn it on, remove the DC 
       power cable from your vehicle's cigarette lighter socket and check
       the socket for debris.  Also, check the fuse in the power cable and
       your vehicle's fuse block.

CONNECTING AN EXTERNAL SPEAKER OR HEADPHONES

You can connect an optional external speaker or pair of headphones with a 
1/8-inch plug to the scanner.  Use an 8-Ohm external speaker or monaural
headphones capable of handling 3 watts of power (such as Cat. No. 21-549 or
20-210).

Insert the speaker's or headphones' plug into the EXT SP jack on the back
of the scanner.

NOTE:  Plugging in an external speaker or headphones disconnects the 
       scanner's internal speaker.

LISTENING SAFELY

To protect your hearing, follow these guidelines when you use headphones.

    Set OFF/VOL 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.
