CONNECTING OPTIONAL POWER SOURCES

Using AC Power

To operate the scanner from AC power, you need an AC adapter such as Radio
Shack Cat. No. 273-1665.

Cautions:

* 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 plug into the AC outlet.

* 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 PWR and CHG jacks. 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 AC 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 PWR 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 CHG jack. Simply
      remove the rubber cap from the CHG jack, connect the AC adapter's
      barrel plug to the jack, then plug the adapter's power module into a
      standard AC outlet. This powers the scanner and recharges the
      batteries at the same time.

Using Vehicle Battery Power

To operate the scanner from your vehicle's battery, you need a DC
cigarette lighter adapter such as Cat. No. 270-1560.

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 PWR and CHG jacks. The
  recommended adapter meets these specifications. Using an adapter that
  does not meet these specifications could seriously damage the scanner or
  the adapter.

* 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. Always unplug the adapter from the 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.  Plug the adapter's barrel plug into the scanner's PWR jack. Then plug
     the other end of the adapter into your vehicle's cigarette lighter
     socket.

Notes: 

* If you installed rechargeable nickel-cadmium batteries in the scanner,
  you can connect the DC cigarette lighter adapter to the CHG jack. Simply
  remove the rubber cap from the CHG jack, connect the adapter's   
  barrelplug to the jack, then plug the other end of the adapter into your
  vehicle's cigarette lighter socket. This powers the scanner and
  recharges the batteries at the same time.

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

CONNECTING A MOBILE OR BASE- STATION ANTENNA

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

When deciding on a mobile or base-station antenna and its location,
consider the following:

* The antenna should be mounted as high as possible.

* The antenna and antenna cable should be as far as possible from sources
  of electrical noise (appliances, ignition systems, gauges, and so on).

* The antenna should be vertical for the best performance.

When connecting an optional antenna, always use 50-ohm coaxial cable, such
as RG-58 (Cat. No. 278-1314) or RG-8/M (Cat. No. 278-1313). For lengths
over 50 feet, use RG-8 low-loss dielectric coaxial cable (Cat. No. 278-
1312). If the coaxial cable's connector does not fit in the scanner's ANT
jack, you might also need a PL- 259-to-BNC antenna plug adapter, such as
Cat. No. 278-120. Your local Radio Shack store carries a wide variety of
coaxial antenna cable and connectors.

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 top
of the scanner.

Cautions: 

* Do not route the cable over sharp edges or moving parts.

* Do not run the cable next to power cables.

* Do not run the cable through a vehicle's engine compartment or other
  areas that produce extreme heat.

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, you can plug an optional earphone or monaural
headphones (such as Cat. No. 33-175 or Cat. No. 20-210, not supplied) into
the jack on top of your scanner. This automatically disconnects the
internal speaker. Your local Radio Shack store has a wide selection of
earphones.

Note: In a noisy area, monaural headphones might provide more comfortable
      listening.

Listening Safely

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

* Set the volume 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.

Traffic Safety

Do not wear an earphone or headphones while operating a motor vehicle or
riding a bicycle. This can create a traffic hazard and is illegal in some
areas.

Even though some earphones and headphones are designed to let you hear
some outside sounds when listening at normal volume levels, they still
present a traffic hazard.

CONNECTING AN EXTENSION SPEAKER

In a noisy area, an extension speaker (such as Cat. No. 21-549) or an
amplified speaker (such as 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 jack.
