PRO-2039 Scanner  (200-0462)        Preparation        Faxback Doc. # 15924

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

The 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                      |
--------------------------------------------------------------------------

|        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.  The 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.  The 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
back of the scanner.

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

To power the scanner, 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.

The memory backup circuit begins to function a few minutes after you
connect the scanner to AC 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.

RESETTING AND INITIALIZING THE SCANNER

If the scanner's display locks up or the scanner does not work properly
after 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 into 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 RESET hole on the back of the scanner.

3.  Release RESET.  When information 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.

UNDERSTANDING THE SCANNER

A Look at the Keyboard

A quick glance at this section should help you understand each key's
function.

SCAN -               scans through the programmed channels.

MAN -                stops scanning to let you directly enter a channel
                     number.

L/OUT -              lets you lock out selected channels.

DELAY -              programs a 2-second delay for the selected channel.

LIMIT -              sets the frequency range you want to search.

UP and DOWN ARROWS - search up or down from the currently displayed
                     frequency.

MON -                accesses the 10 monitor memories.

SPEED -              selects a low or high scanning/search speed.

                     particular channel.

CLEAR -              clears an incorrect entry.

PGM -                programs frequencies into channels.

Number Keys -        each key has a single digit label and a range of
                     numbers above it.  Use the digits on the keys to enter
                     the numbers for a channel or a frequency.  Use the 
                     range of numbers above the key (61-80, for example) to
                     select the channels in a channel-storage bank (see
                     "Understanding Channel-Storage Banks").

.(dot) -             enters a decimal point when you enter a frequency.

ENTER -              stores a frequency in a channel.

A Look at the Display

The display has several indicators that show the scanner's current
operating mode.  A quick look at the display will help you understand how
to operate the scanner.

BANK -               bars to the right of this indicator show which memory
                     banks are turned on for scanning.

CH -                 appears with a number (1-200) to show which of the
                     scanner's 200 channels it is tuned to.

MHz -                appears with digits to show which of the 31,000
                     possible frequencies the scanner is tuned to.

UP and DOWN arrows - indicate the search direction.

DELAY -              appears when the scanner stops at a channel you
                     programmed for a 2-second delay.

PGM -                appears when you program frequencies into the
                     scanner's channels.

L/OUT -              appears when you lock out a channel or manually
                     select a locked-out channel.

UNDERSTANDING MEMORY

You can store frequencies into either a permanent memory location, called
a channel, or a temporary memory location, called a monitor memory.  You
can store up to 200 channels and 10 monitor memories.

CHANNEL-STORAGE BANKS

To make it easier to identify and select the channels you listen to most
often, channels are divided into 10 channel-storage banks (1 to 10) of 20
channels each.  You can use each channel-storage bank to group frequencies,
such as those used by the police department, fire department, ambulance
services, or aircraft (see "Guide to the Action Bands").

For example, there might be three or four police departments in your area,
each using several different frequencies.  Additionally, there might be
other law enforcement agencies such as state police, county sheriffs, or
SWAT teams that use their own frequencies.  You could program all law
enforcement frequencies starting with Channel 1 (Bank 1), then program the
fire department, paramedic, and other public safety frequencies starting
with Channel 21 (the first channel in Bank 2).

MONITOR MEMORIES

The scanner also has 10 monitor memories.  You can use these memories to
temporarily store frequencies while you decide whether or not to save them
in channels.  This is handy for quickly storing an active frequency when
you search through an entire band.

NOTES:  To store a frequency into a monitor memory, you must perform a
        limit or direct search.  See "Searching For and Temporarily
        Storing Active Frequencies."

        You can select monitor memories manually, but you cannot scan
        them.  See "Using Monitor Memories."
