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

1.  Insert the supplied AC adapter's barrel plug into the AC10V jack on
    the back of the scanner.

2.  Plug the other end of the AC adapter into a standard AC outlet.

The memory backup circuit begins to function 1 to 2 minutes after you
plug in the scanner.  During a power loss, the memory backup circuit
protects the channels you stored in memory for up to three days.


The supplied telescoping antenna helps the scanner receive strong local
signals.  To install the antenna, screw it clockwise into the hole on the
scanner's top.

Adjust the length of the telescoping antenna for the best reception.  The
scanner's sensitivity depends on the antenna's length and various
environmental conditions.  Generally, for the best overall reception of
most transmissions, you should extend the telescoping antenna to its full
length.  However, reception of transmissions in the 406-512 MHz bands is
sometimes improved if you do not extend the antenna fully.

Connecting an Optional Antenna

Instead of the supplied antenna, you can connect an outdoor base antenna
to the scanner.  The local Radio Shack store sells a variety of antennas.
Each type has benefits, and you should choose the one that best meets
your needs.

When deciding on an outdoor base antenna and its location, also 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, etc).

The antenna should be vertical for best performance.

Once you choose an antenna, follow the mounting instructions that come
with it.  Then route the antenna cable to the scanner.  Connect the cable
to the ANT jack on the back of the scanner.

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

Use coaxial cable to connect an optional antenna.  Always use 50-ohm
coaxial cable, such as RG-58 or RG-8.  For lengths over 50 feet, use RG8
low-loss dielectric coaxial cable.  If the coaxial cable's connector will
not fit in the ANT jack, you may also need a scanner antenna plug adapter
(Cat. No. 278-208).

NOTE:  The local Radio Shack store carries a wide variety of coaxial
       antenna cable and connectors.

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 the 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.


You can connect an optional external speaker or pair of headphones to the
scanner.  Use an 8-ohm external speaker or headphones capable of handling
3 to 10 watts of power (such as Radio Shack Cat. No. 21-549 or Cat. No.
20-210).  The speaker's or headphone's cable must have a 1/8-inch plug.
Simply plug the speaker's or headphone's cable into the scanner's EXT SP

NOTE:  When you connect an external speaker or headphones, the scanner's
       internal speaker disconnects.


If the scanner's display locks up or does not work properly after you
connect power, you might have to reset the scanner.

CAUTION:  This procedure clears all the information you have programmed
          into the scanner.  Use this procedure only when you are sure
          the scanner is not working properly.

1.  Turn off the scanner.

2.  While you press and hold down the 2 and 9 keys, turn on the scanner.
