PRO-2002 AM/FM Scanning Receiver
(200-0116)                 Preparation                Faxback Doc. # 18982

Loosen the screw and remove the battery compartment cover; then snap in a
9-volt battery.  (We recommend a Radio Shack long-life alkaline battery,
23-553 or equivalent.)  Your PRO-2002 contains an electronic memory to
preserve the 50 programmed scanner channels.  The battery protects this
memory during AC or DC power failure, or when you have the set unplugged.

Your PRO-2002 can keep channels stored in its memory for a short period of 
time even with the AC cord unplugged and the 9-volt battery disconnected.  
(This is so you can replace the battery with the AC cord unplugged, 
without losing all the programmed information.)  For best results, replace 
the battery every six months. 

CAUTION:  Never leave a weak or dead battery in your PRO-2002; even 
          "leakproof" types can leak damaging chemicals.  Battery life is 
          about one month when AC or DC power is off for a prolonged 
          period. 

Your PRO-2002 comes with a Telescopic Antenna.  Insert into the Telescopic 
Antenna jack on the top of your PRO-2002 and screw into place.  Extend to 
its full length. 

For very best reception, you'll need an external antenna.  Your local Radio
Shack has an excellent antenna for both VHF and UHF reception (Cat. No.
20-176).  You can also find mounting hardware, cables and connectors from
Radio Shack too.  You'll find that reception improves the higher you mount
the antenna.

Connect your Receiver to a standard 120 volt AC wall outlet.  When you
first plug in your PRO-2002, you might notice that the Display in flashing
on and off.  Don't be alarmed-this is normal!  To stop the Display from
flashing, just press the CLOCK Key.

MOBILE INSTALLATION

Safety and operating convenience are the primary factors to consider when
you install any equipment in a vehicle.  Be sure you can easily reach the
Receiver's controls.  Also, be sure the connecting cables do not interfere
with the operation of the vehicle (brake, accelerator, etc.).

You can mount the Receiver to the underside of the dash or instrument panel
in the vehicle.  Use the universal mounting bracket provided.  Take care
when drilling holes that you do not drill into existing wires or trim.

The PRO-2002 is designed to operate from a negative ground 12-volt DC
source.  Be sure you connect power leads with the correct polarity.  Use
the DC Power cable provided.

The cable has two (brown and red) + leads and one black - lead.  Connect
the brown lead to accessory terminal, red lead to + 12 volt always alive,
and black lead to the negative ground.  Be sure to observe correct voltage
polarity:  brown and red to "+" and black to "-."

IMPORTANT:  If your car has been burning out headlamps and other bulbs at
            a rapid rate, first have the voltage regulator checked for
            proper output: excessive voltage (more than 16 volts) can  
            damage your Receiver.

NOTE:  The clock in your PRO-2002 will keep working even if the ignition is
       off.  It will draw approximately 120mA of current.  If you're not
       going to use your vehicle for a few days (such as a weekend), set
       the DC CLOCK/OUT switch on the rear of your receiver to OUT.  This
       will turn off your PRO-2002'S clock and protect you vehicle's
       battery.  When you use your vehicle again, set DC CLOCK/OUT switch
       to DC CLOCK and then reset clock to correct time.

Mobile Antenna

There are many possible mounting locations on a car. 

A convenient and efficient antenna for mobile use is Radio Shack's  VHF-
Hi/Lo UHF-Hi/Lo No-Hole Trunk Mount Mobile, 20-017.

Keep the following points in mind when installing your mobile antenna.

1.  Mount it rigidly, so it will remain vertical while in motion.

2.  Mount as far as possible from the engine compartment.

MOBILE NOISE SUPPRESSION

Your PRO-2002 is a very sensitive receiver, and will pick up even extremely
weak signals.  This means that in addition to the tiny radio signals,
radio-frequency noise may also be picked up and amplified.

In a mobile installation, it is important that you take steps to reduce the
amount of noise that finds its way into the Receiver.  If you take some or
all of the steps recommended below, your reception should be quite
satisfactory for mobile applications.

Electrical System:

Generally speaking, noise can be generated by any device or connection that
carries electrical current.  Any device that generates a spark should also
be suspected.  Bypass any suspected wire to ground with a high quality 1uF
coaxial capacitor.

A very common source of noise is the generator or alternator.  This type
of noise will sound like a musical whine, and will also vary with speed of
the engine.  Generator and alternator noise can usually be reduced by
connecting a coaxial-type capacitor from the armature terminal to the
metal case.

Ignition System:

The ignition system is the most common source of noise.  This noise can be
identified by the fact that its speed varies with the engine speed. 
Ignition noise will sound like a series of "popping" sounds, while the
engine is idling, and will speed up to a buzzing sound as engine speed is
increased.

There are a number of things that can be done for this type of noise.

1.  Use radio suppression-type ignition wire and resistor spark plugs.

2.  Check high-voltage wiring for leakage, cracks, etc.  Replace any
    wiring.

3.  In extreme cases, obtain an ignition noise suppression kit-it should
    shield all ignition wiring.  This will provide maximum suppression.
