(200-0505)                 Preparation                Faxback Doc. # 47806

POWER SOURCES

You can power your scanner from any of these power sources:

  Internal batteries

  Standard AC power (using an optional AC adapter)

  Vehicle battery power (using an optional DC adapter)

Using Internal Batteries

You can power your scanner with four AA batteries.  For the longest
operation and best performance, we recommend alkaline batteries, such as
Cat. No. 23-552.  Or, you can use rechargeable nickel-cadmium batteries
(Cat. No. 23-125).

Follow these steps to install or replace batteries.

1.  If the scanner is on, turn VOLUME/OFF fully counterclockwise until it
    clicks to turn it off.

2.  Press down the tab on the battery compartment cover, and lift open the
    compartment.

3.  Remove any old batteries from the compartment and cover.

    CAUTION:  Always dispose of old non-rechargeable batteries promptly
              and properly.  Do not bury or burn them.

4.  Install two batteries in the compartment and two in the cover as
    indicated by the polarity symbols (+ and -) marked inside the
    compartment and cover.

5.  Replace the cover.

If BATT.Lo flashes on the display, immediately replace or recharge all
four batteries.  See "Important Information About the External Power
Jacks" and "Charging Nickel-Cadmium Batteries", below.

IMPORTANT INFORMATION ABOUT THE EXTERNAL POWER JACKS

The scanner has two external power jacks - POWER and CHARGE.  It is
important that you understand the purpose of each jack before you connect
any adapter to the scanner.

The POWER jack powers the scanner and disconnects the internal batteries.
You can use this jack with either an AC or DC adapter, regardless of the
type of batteries you installed.

The CHARGE jack powers the scanner and also charges the internal
batteries.  Use the CHARGE jack only when rechargeable nickel-cadmium
batteries are installed.

WARNING:  Never use the CHARGE jack with non-rechargeable batteries.  If
          you try to recharge non-rechargeable batteries, they become very
          hot and could explode.

USING AC POWER

To operate the scanner from AC power, you need an AC adapter such as
RadioShack Cat. No. 20-188.

CAUTIONS:  You must use an AC adapter that supplies 9 volts and delivers
           at least 300 milliamps.  Its center tip must be set to negative
           and its plug must correctly fit the scanner's POWER jack.  The
           recommended adapter meets these specifications.  Using an
           adapter that does not meet these specifications could seriously
           damage the scanner or the adapter.

           Always plug the adapter's barrel plug into the scanner before
           you plug the adapter's power module into the AC outlet.  Always
           unplug the adapter's power module from the AC outlet before you
           unplug the adapter's barrel plug from the scanner.

Plug the adapter's barrel plug into the scanner's POWER jack.  Then plug
the adapter's power module into a standard AC outlet.

Note:  If you installed rechargeable nickel-cadmium batteries in the
       scanner, you can connect the AC adapter to the CHARGE jack.  This
       powers the scanner and recharges the batteries at the same time.
       See "Charging Nickel-Cadmium Batteries", below.

USING VEHICLE BATTERY POWER

You can power the scanner from your vehicle's battery power, using a DC
adapter such as RadioShack DC Universal Adapter, Cat. No. 270-1560A.

CAUTIONS:  You must use a DC adapter that supplies (regulated) 9-volt
           power and delivers at least 300 milliamps.  Its center tip must
           be set to negative, and its plug must correctly fit the
           scanner's POWER jack.  Using an adapter that does not meet
           these specifications could seriously damage your scanner or the
           adapter.

           Your vehicle must have a 12-volt, negative-ground electrical
           system.

           To protect your vehicle's electrical system, always plug the
           adapter into the scanner before you plug it into your vehicle's
           cigarette-lighter socket before you unplug it from the scanner.

Follow these steps to connect the DC adapter

1.  Connect the DC adapter's orange barrel plug to the adapter's cable,
    with the tip set to (-) (negative).

2.  Set the adapter's voltage switch to 9V.

3.  Insert the barrel plug into the scanner's POWER jack.

4.  Plug the other end of the adapter into your vehicle's cigarette
    lighter socket.

Note:  If the scanner does not operate properly when you use a DC adapter,
       unplug the adapter from the lighter socket and clean the socket to
       remove ashes and other debris.

CHARGING NICKEL-CADMIUM BATTERIES

The scanner has a built-in charging circuit that lets you recharge
nickel-cadmium batteries while they're in the scanner.  To charge the
batteries, simply connect an AC or DC adapter to the scanner's CHARGE
jack.

WARNING:  Do not connect either adapter to the scanner's CHARGE jack if
          you installed non-rechargeable batteries (standard, extra-life,
          or alkaline).  Non-rechargeable batteries become hot and can
          even explode if you try to recharge them.

It takes about 10 to 18 hours to recharge batteries that are fully
discharged.  You can operate the scanner while recharging nickel-cadmium
batteries, but the charging time is lengthened.

CAUTIONS:  Do not overcharge nickel-cadmium batteries.

           To prevent damaging nickel-cadmium batteries, never charge them
           in an area where the temperature is above 90 degrees F or below
           40 degrees F.

IMPORTANT:  Your scanner is capable of using rechargeable nickel-cadmium
            batteries.  At the end of the batteries' useful life, they
            must be recycled or disposed of properly.  Contact your local,
            county, or state hazardous waste management authorities for
            information on recycling or disposal programs in your area.
            Some options that might be available are: municipal curb-side
            collection, drop-off boxes at retailers, recycling collection
            centers, and mail-back programs.

RESETTING THE SCANNER

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 programmed into
          the scanner.  Use this procedure only when you are sure your
          scanner is not working properly.

1.  If the scanner is on, turn VOLUME/OFF fully counterclockwise until it
    clicks to turn it off.  Then wait a few seconds.

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

CONNECTING THE ANTENNA

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

1.  Align the slots around the antenna's connector with the tabs on the
    antenna jack.

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

Connecting an Optional antenna

The scanner's antenna jack lets you use your scanner with a variety of
antennas.  The supplied antenna provides adequate reception in most areas,
but you can connect an optional antenna such as an external mobile antenna
or outdoor base antenna.  Your local RadioShack store sells a variety of
antennas.

To connect an outdoor antenna, 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.  If your antenna's cable does not have a BNC connector, you will
also need a BNC adapter (available at your local RadioShack store).

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

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 AN EARPHONE HEADPHONES

For private listening, plug an earphone or headphones into the (headphone)
jack on top of your scanner.  This automatically disconnects the internal
speaker.  Your local RadioShack store has a wide selection of earphones
and headphones.

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 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.

CONNECTING AN EXTENSION SPEAKER

In a noisy area, an extension speaker (such as RadioShack cat. No. 21-549)
or an amplified speaker (such as RadioShack Cat. No. 21-541), positioned
in the right place, might provide more comfortable listening.  Plug the
speaker cable's 1/8-inch mini plug into your scanner's (headphone) jack.

ATTACHING THE BELT CLIP

You can attach the supplied belt clip so you can easily use the scanner
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.
