You can power your scanner from any of three sources:

    Internal battery power

    Standard AC power (using an optional AC adapter [273-1665])

    Vehicle battery power (using an optional DC adapter [270-1560])


You can operate your scanner from four AA batteries.  For longest
operation and best performance, we recommend alkaline batteries (Radio
Shack Cat. No. 23-552).  Or, you can use rechargeable nickel-cadmium
batteries (Cat. No. 23-125).

WARNING:  The scanner has a built-in circuit that lets you recharge
          nickel-cadmium batteries inside the battery compartment. 
          However, you must never use this circuit when you have installed
          non-rechargeable batteries in the scanner.

To install batteries in your scanner, follow these steps.

1.  Press down on the arrow and slide the cover in the direction of the
    arrow to remove the battery compartment cover.

2.  Pull the ribbon to remove the battery holder from the compartment and
    remove any old batteries.

3.  Install four AA batteries, as indicated by the polarity symbols (+ and
    -) marked on the battery holder.

4.  Place the battery holder in the compartment so the holder's metal
    contacts line up with the metal contacts in the battery compartment.

5.  Replace the battery compartment cover.

    You scanner beeps every 15 to 30 seconds when the batteries are low. 
    When this happens, immediately replace or recharge all four.


Follow these steps to attach the supplied flexible antenna to the
connector on the top of your scanner.

1.  Slip the slot in the antenna's connector over the protrusion on the

2.  Press down and rotate the antenna's base until it locks into place.

Connecting an Optional Antenna

The antenna connector on your scanner makes it easy to use your scanner
with a variety of antennas.  You can remove the supplied antenna, if you
want, and attach a different one, such as an external mobile antenna or
outdoor base antenna.  Your local Radio Shack store sells a variety of

Use coaxial cable to connect an outdoor 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.  You will also need a BNC connector to
connect an optional antenna (Cat. No. 278-103 or 278-185).

WARNING:  When installing or removing an outdoor antenna, use extreme
          caution.  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.


For private listening, plug an earphone or headphones into the EARPHONE
jack on top of your scanner.  This automatically disconnects the internal
speaker.  We recommend Radio Shack's earphone (Cat. No. 33-175) or mono
headphones (Cat. No. 20-210).

Hearing Comfort and Your Health

To protect your hearing, follow these guidelines when you use an

    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 not wear headphones or an earphone while you drive a vehicle or ride a
bicycle.  This can create a traffic hazard and is illegal, in some areas. 
Even though some headphones and earphones are designed to let you hear
some outside sounds when you listen at normal levels, they still present a
traffic hazard.


In a noisy area, an extension speaker, such as Radio Shack's Cat. No. 21-
539, positioned in the right place, might provide more comfortable
listening.  Plug the speaker cable's 1/8-inch mini-plug into your
scanner's EARPHONE jack.


If the scanner's display locks up or does not work properly after you
connect a power source, 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
          your 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.


You can use the supplied belt clip to make the scanner easier to use when
you are on the go.  Use the two supplied screws to attach the belt clip to
the scanner.  Then slide the belt clip over your belt or waistband.
