PRO-2037 Programmable Scanner
(200-0461)                 Preparation                Faxback Doc. # 37889


This scanner is primarily designed for use in the home as a base station.
You can place it on a desk, shelf, or table.

Your scanner's front feet fold up or down.  Adjust them to give you the
best view of the display.

CONNECTING THE ANTENNA

To attach the supplied telescoping antenna, simply screw it clockwise into
the hole on the scanner's top.

The scanner's sensitivity depends on the antenna's length and various
environmental conditions.  For the best reception of the transmissions you
want to hear, adjust the antenna length.

Frequency Antenna Length

30-174 MHz         extend fully

380-512 MHz        extend 2 segments

806-960 MHz        collapse fully
                   (1 segment only)

Connecting an Optional Antenna

The telescoping antenna is adequate for strong local signals.  But, for
improved reception, you can connect a multi-band outdoor antenna
(not supplied) to the scanner.  Your local Radio Shack store sells a
variety of antennas.  Choose the one that best meets your needs.

When deciding on an outdoor base antenna and its location, consider the
following:

    The location of the antenna should be as high as possible.

    The antenna and antenna cable should be as far as possible from
    sources of electrical noise (appliances, other radios, and so on).

    The antenna should be vertical for the best performance.

    To connect an Optional antenna, always 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 the coaxial cable's connector does not
    fit in the 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.

    Caution:

    Do not run the cable over sharp edges or moving objects.

    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 POWER

You can power your scanner from either of these sources:

    Standard AC power

    Vehicle battery power (using an optional DC adapter)

The memory backup circuit begins to function a few minutes after you
connect the scanner to AC or DC power.  If a power failure occurs or if
the power cord is disconnected, this circuit protects information in the
scanner's memory for about 1 hour.

Connecting AC Power

Plug the scanner's AC power cord into a standard AC outlet.

    Caution:

    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.

Connecting DC Power

You can power your scanner from your vehicle's cigarette-lighter socket
using a DC adapter (Radio Shack Cat. No. 270-1533).

    Cautions:

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

    You must use a DC adapter that supplies 12 volts and delivers at least
    500 mA and its plug must correctly fit the DC 13.8 V jack on the back
    of the scanner.  The recommended adapter meets these specifications.
    Using an adapter that does not meet these specifications could
    seriously damage the scanner or the adapter.

    Insert the DC adapter's small barrel plug into the DC 13.8 V jack on
    the scanner's back.  Then plug the other end of the DC adapter into
    your vehicle's cigarette-lighter socket.

RESETTING AND INITIALIZING THE SCANNER

If the scanner's display locks up or the scanner does not work properly
later you connect power, you might have to reset the scanner's display or
initialize the scanner.

Resetting the Scanner's Display

1.  Turn off the scanner, then turn it on again.

2.  Insert a pointed object, such as a straightened paper clip, into the
    RESET hole on the back of the scanner.

If the scanner still does not work properly, you might have to initialize
the scanner.

Initializing the Scanner

    Caution:

    This procedure clears all information you programmed in the scanner's
    memory.  Initialize the scanner only when you are sure the scanner is
    not working properly.

1.  Turn off the scanner, then turn it on again.

2.  Press and hold down CLEAR and insert a pointed object, such as a
    straightened paper clip, into the RESET hole on the back of the
    scanner.

3.  Release RESET.  When the display reappears, release CLEAR.

    Note:

    You must release RESET before releasing CLEAR in order to clear the
    memory.

CONNECTING HEADPHONES

For private listening, you can connect an optional pair of headphones with
a 1/8-inch plug to the scanner.  Use monaural headphones, such as
Cat. No. 20-210.

Insert the headphones' plug into the HEADPHONE jack on the front of the
scanner.

    Note:

    Plugging in headphones automatically disconnects the internal speaker.

Listening Safely

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

    Set the volume to its lowest setting before you begin listening.
    After you put on the headphones, adjust the volume to a comfortable
    listening level.

    Do not listen at extremely high-volume levels.  Extended high-volume
    listening can lead to permanent hearing loss.

    Do not increase the volume once you establish a comfortable listening
    level.  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 while operating a motor vehicle or riding a
bicycle.  This can create a traffic hazard and is illegal in some areas.

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

CONNECTING AN EXTERNAL SPEAKER

You can connect an optional external speaker with a 1/8-inch plug to the
scanner.  Use an 8-ohm external speaker capable of handling over 5 watts
of power, such as Cat. No. 21-549.

Insert the speaker cable's plug into the EXT SPKR jack on the back of the
scanner.

    Note:

    Plugging in an external speaker automatically disconnects the
    scanner's internal speaker.
