PRO-70 50 Channel Portable Scanner
(200-0310)                 Preparation                Faxback Doc. # 39170


Your scanner covers frequencies used by many different groups including
police and fire departments, ambulance services, government agencies, 
private companies, amateur radio services, military operations, pager
services, and wireline (telephone and telegraph) service providers.  It is
legal to listen to almost every transmission your scanner can receive.  
However, there are some transmissions you should never intentionally listen
to.  These include:

     Telephone conversations (either cellular, cordless, or other private
                              means of telephone signal transmission)

     Page transmissions

     Any scrambled or encrypted transmissions

According to the Electronic Communications Privacy Act (ECPA), you are
subject to fines and possible imprisonment for intentionally listening to,
using, or divulging the contents of such a transmission unless you have the
consent of a party to the communication (unless such activity is otherwise
illegal).  RadioShack encourages responsible, legal scanner use.


You can power your scanner from any of three sources:

    Internal batteries or a rechargeable scanner battery pack (not supplied)

    Standard AC power (with an optional AC adapter)

    Vehicle battery power (with an optional DC adapter)


    Connecting an AC or DC adapter to the scanner disconnects any internal
    batteries, but it does not disconnect a rechargeable battery pack.  If
    you install a rechargeable battery pack, you can operate the scanner
    and recharge the battery pack at the same time.

    If the scanner stops working properly after connecting it to power, try
    resetting it.

Using Batteries

You can power your scanner from six AA batteries.  For the longest 
operation and best performance, we recommend alkaline batteries, such as
RadioShack Cat. No. 23-552.  You can also power the scanner from a 
rechargeable scanner battery pack, such as Cat. No. 23-288.

Note:  You can also use six rechargeable nickel-cadmium batteries (such as
       Cat. No. 23-125( to power the scanner.  To charge or recharge 
       nickel-cadmium batteries, however, you must remove them from the
       scanner and use an external charger (such as Cat. No. 23-134).

Follow these steps to install batteries or a battery pack.

1.  Press down on the battery compartment cover on the bottom of the 
    scanner and slide the cover in the direction of the arrow to remove it.
2.  Pull up and slide the battery holder or battery pack out of the battery

3.  If you are installing individual batteries, insert six batteries in the
    battery holder as indicated by the polarity symbols (+ and -) marked on
    the battery holder.

4.  Slide the battery holder or battery pack into the compartment as 
    illustrated inside the compartment.

    Caution:  The battery holder or battery pack fits only one way inside
              the battery compartment.  Do not force it.

5.  Replace the cover.

If BATT flashes on the display, immediately replace all six non-rechargeable
batteries, remove and recharge all six rechargeable batteries, or recharge
the battery pack.  

Caution:  Always dispose of old batteries promptly and properly.  Do not
          bury or burn them.

Using Standard AC Power

To power the scanner from AC power, you need an AC adapter such as 
RadioShack Cat. No. 273-1665.  Plug the adapter's barrel plug into the
scanner's PWR/DC 9V jack.  Then plug the adapter's power module into a
standard AC outlet.

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


   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/DC 9V jack.  The recommended 
   adapter meets these specifications.  Using an adapter that does not meet
   these specifications could damage the scanner or the adapter.

   When you finish using the AC adapter, disconnect it from the AC outlet
   first.  Then disconnect it from the scanner.

Using Vehicle Battery Power

To power the scanner from your vehicle's cigarette lighter socket, you need
a DC Adapter, such as Cat. No. 270-1560.


   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/DC 9V jack.  The
   recommended adapter meets these specifications.  Using an adapter that
   does not meet these specifications could damage the scanner or the

   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.

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 PWR/DC 9V jack.

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

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

Charging a Rechargeable Battery Pack

Your scanner has a built-in charging circuit that lets you charge a
rechargeable scanner battery pack (Cat. No. 23-288, not supplied) while it
is in the scanner.  To charge a battery pack, simply connect an appropriate
AC or DC adapter to the PWR/DC 9V jack.

Note:  If you want to take the battery pack out of the scanner to charge it
       follow the instructions provided with the battery pack.

It takes about 14-16 hours to recharge a battery pack that is fully 
discharged.  You can operate the scanner while recharging the battery pack,
but the charging time is lengthened.

Note:  A rechargeable battery pack lasts longer and delivers more power if
       you occasionally let it fully discharge.  To do this, simply use
       the scanner until BATT appears on the display.  Then fully charge
       the battery pack.

Important!  At the end of a rechargeable battery pack's useful life, it 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.


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

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

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

Connecting an Optional Antenna

The antenna connector on your scanner makes it easy to use the scanner with
a variety of antennas.  Instead of the supplied antenna, you can attach
a different one, such as an external mobile antenna or outdoor base station
antenna.  Your local RadioShack store sells a variety of antennas.

Always use 50-ohm coaxial cable, such as RG-58 or RG-8, to connect an
outdoor antenna.  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 (also available at your local RadioShack 

Follow the installation instructions supplied with the antenna, route the
antenna cable to the scanner, then connect it to the ANT jack.

Warning:  Use extreme caution when installing or removing 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.


For private listening, you can plug an earphone or mono headphones (such as
Cat. No. 33-175 or 20-210) into the headphone jack on top of your scanner.
This automatically disconnects the internal speaker.

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 an earphone or headphones while you are driving a vehicle or
ride a bicycle.  This can create a traffic hazard and is illegal in some

Even though some earphones and headphones 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 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 1/8-inch
mini-plug into your scanner's headphones jack.


You can use the belt clip attached to the back of the scanner for hands-free
carrying when you are on the go.  Simply slide the belt clip over your
belt or waistband.


Your scanner might cause TV or radio interference even when it is operating
properly.  To determine whether your scanner is causing the interference,
turn off your scanner.  If the interference goes away, your scanner is
causing the interference.  Try the following methods to eliminate the

    Move your scanner away from the TV or radio

    Connect your scanner to an outlet that is on a different electrical
    circuit from the TV or radio

    Contact your local RadioShack store for help

If you cannot eliminate the interference, the FCC requires that you stop
