This scanner is primarily designed for use in the home as a base station.
You can place it on a desk, shelf, or table.

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, screw it clockwise into the hole on the
scanner's top.

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

   29-54 MHz                 Extend fully

   137-174 MHz               Collapse one segment

   406-512 MHz               Collapse both segments

Connecting an Outdoor Antenna

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

When deciding on a base-station antenna and its location, consider these
points:

  The antenna should be as high as possible on the house.

  The antenna and its cable should be as far as possible from sources of
  electrical noise (appliances, other radios, etc.).

  The antenna should be vertical for the best performance.

To connect an optional base-station 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 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, you might also need a 
Motorola-to-BNC antenna plug adapter, such as RadioShack Cat. No. 278-117.
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 the scanner and connect the
cable to the ANT jack on the back of the scanner.

CAUTIONS:  Do not run the cable over sharp edges or moving parts that
           might damage it.

           Do not run the cable next to power cables or other antenna
           cables.

           Follow all cautions and warnings included with your antenna.

CONNECTING POWER

The scanner's supplied AC adapter lets you power the scanner from a
standard AC outlet.  To connect power to the scanner, insert the AC
adapter's barrel plug into the AC 10V jack on the back of the scanner,
then plug the AC adapter into a standard AC outlet.

WARNING:  Do not use the AC adapter's polarized plug with an extension
          cord receptacle unless the blades can be fully inserted to
          prevent blade exposure.

CAUTION:  Use only the supplied AC adapter to power your scanner.  Using
          another adapter could damage your scanner. A replacement adapter
          is available by special order through your local RadioShack
          store.

          Be sure to connect the AC adapter to the scanner before you
          connect it to an AC outlet, and disconnect the AC adapter from
          the AC outlet before you disconnect it from the scanner.

CONNECTING AN EXTERNAL SPEAKER

You can connect an optional external speaker with a 1/8-inch plug to the
scanner.  Use an 8-Ohm external speaker that can handle at least 2.5 watts
of power.  RadioShack stores sell scanner accessories, including external
speakers.

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

Note:  Plugging in an external speaker disconnects the scanner's internal
       speaker.

CONNECTING AN EARPHONE/HEADPHONES

You can connect an optional earphone or pair of monaural headphones with
a 1/8-inch plug to the scanner.  Your local RadioShack store sells a
complete line of earphones and headphones.

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

Note:  Plugging in an earphone or headphones disconnects the scanner's
       internal speaker.

Listening Safely

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

  Set OFF/VOLUME to the lowest setting before you begin listening.  After
  you put on the earphone or headphones, adjust OFF/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 OFF/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.
