PRO-2039 Scanner  (200-0462)       Operation           Faxback Doc. # 15925

TURINING ON THE SCANNER/SETTING VOLUME AND SQUELCH

1.  Turn SQUELCH full counter-clockwise.

2.  Turn VOLUME clockwise until you hear a hissing sound.  The scanner
    automatically scans all 10 banks.

3.  Slowly turn SQUELCH clockwise, then leave it set to a point just after
    the hissing stops.

NOTE:  If the scanner picks up unwanted weak transmissions, turn SQUELCH
       clockwise to decrease the scanner's sensitivity to these signals. 
       If you want to listen to a weak or distant station, turn SQUELCH
       counter-clockwise.

SCANNING THE CHANNELS

To begin scanning the channels or to start scanning again after monitoring
a channel, press SCAN.  The scanner scans either up or down through all
non-locked channels in the active banks (see "Locking Out Channels").

NOTE:  An improper SQUELCH setting might keep the scanner from scanning
       (see "Turning on the Scanner/Setting Volume and Squelch").

TURNING CHANNEL-STORAGE BANKS ON AND OFF

When you first turn on the scanner, the scanner scans all ten channel
storage banks.  As the scanner scans a bank, the bar under the bank's
number flashes.

To turn off banks while scanning, repeatedly press the bank's number key
until the bar under the bank's number disappears.  The scanner does not
scan any of the stored channels within banks you have turned off.

NOTES:  You cannot turn off all banks.  There must be at least one active
        bank.

        You can manually select any channel in a bank, even if the bank is
        turned off.

To turn on banks while scanning, press the bank's number key until the bar
appears under the bank's number.

STORING FREQUENCIES

Good references for active frequencies are Radio Shack's "Police Call Radio
Guide Including Fire and Emergency Services," "Official Aeronautical
Frequency Directory," and "Maritime Frequency Directory."  We update these
directories every year, so be sure to get a current copy.  See also "Guide
to the Action Bands" in this manual.

If you do not have a reference to frequencies in your area, you can use a
limit or direct search to find a transmission.

You can store up to 200 frequencies into the scanner's channels.  Follow
these steps to store frequencies.

1.  Press MAN.  Enter the channel number you want to program.

2.  Press PGM.  PGM appears on the display.

3.  Using the number keys, enter the frequency you want to store in that
    channel.

4.  Press ENTER to store the frequency.

    If you make a mistake in Step 3, ERROR appears on the display.  Press
    CLEAR and repeat Steps 3 and 4.

5.  Repeat Steps 1-4 to program more channels or Steps 2-4 if you want to
    program the next channel in sequence.

SEARCHING FOR AND TEMPORARILY STORING ACTIVE FREQUENCIES

You can search for frequencies using either of the following methods, then
temporarily store the frequencies in monitor memories.

    Limit search (within a range of frequencies you selected)

    Direct search (any range of frequencies before or after a frequency you
    selected)

Limit Search

Limit search lets you search for active frequencies within a range you
select, so you can choose which ones you want to store.

NOTE:  You can use the scanner's delay feature while using limit search
       (see "Delay").

Follow these steps to search for active frequencies.

1.  Press PGM, then LIMIT.  LO appears on the display.

2.  Using the number keys, enter the lower limit of the frequency range.

NOTE:  If you enter an invalid frequency in Step 2 or 4, ERROR appears on
       the display.  Simply repeat the step.

3.  Press ENTER, then LIMIT.  HI appears on the display.

4.  Using the number keys, enter the upper limit of the frequency range.

5.  Press ENTER.

6.  Press UP arrow to search from the lower to the upper limit, or press
    DOWN arrow to search from the upper to the lower limit.  -L-, SRCH,
    and UP or DOWN arrows appear on the display.

7.  When the scanner stops on a transmission, press MON to store the
    frequency in the current monitor memory, or press UP or DOWN arrow to
    continue the search.

Direct Search

When the scanner is stopped on a frequency, you can search up or down from
the current displayed frequency to find more frequencies you want to store.

NOTE:  You can use the scanner's delay feature while using direct search
       (see "Delay").

1.  Press MAN or PGM.

2.  Use the number keys to enter the frequency you want to start the search
    from.  Or, use the number keys to enter the channel number containing
    the starting frequency.  Then press MAN or PGM.

3.  Press UP arrow to search up or DOWN arrow to search down from the
    frequency.  -d-, SRCH, and UP or DOWN arrows appear on the display.

4.  When the scanner finds an active frequency, it stops searching.  To
    save the frequency into a current monitor memory, press MON.  The bar
    under the memory number stops flashing.

5.  Press UP or DOWN arrows again to continue searching for more active
    frequencies.

MOVING A FREQUENCY FROM A MONITOR MEMORY TO A CHANNEL

1.  Press MAN.

2.  Use the number keys to enter the channel number where you want to store
    the monitor frequency.  Then press PGM.

3.  Press MONITOR and the number of the monitor memory that has the
    frequency you want to store.  MONITOR and the frequency appear on the
    display.

4.  Press ENTER.  The scanner stores the frequency into the channel.

MANUALLY SELECTING A CHANNEL

You can continuously monitor a specific channel without scanning.  This is
useful if you hear an emergency broadcast on a channel and do not want to
miss any details (even though there might be periods of silence) or if you
want to monitor a locked-out channel.

To select a channel, just press MAN.  Enter the channel number, and press
MAN again.  Or, if the scanner is scanning and stops at the desired
channel, just press MAN one time.  Pressing MAN additional times makes the
scanner step through the channels.

SPECIAL FEATURES

DELAY

Many agencies use a two-way radio system that might have a pause between a
query and a reply.  The scanner's delay feature waits for 2 seconds after
each transmission while scanning or searching.

To program a 2-second delay for any channel while scanning, manually select
the channel and press DELAY until DELAY appears on the display.  When the
scanner stops on the channel, it waits for 2 seconds after each
transmission before it resumes scanning.

To program a 2-second delay for any active frequency while searching, press
DELAY until DELAY appears on the display.  When the scanner stops on a
frequency, it waits for 2 seconds after each transmission before it resumes
searching.

To turn off the programmed delay on any active channel, press DELAY while
the channel is still active.  DELAY disappears from the display.

LOCKING OUT A CHANNEL

You can scan channels faster by locking out those that have a continuous
transmission, such as a weather channel.

To lock out a channel while scanning, press L/OUT when the scanner stops on
the channel.  To lock out a channel manually, manually select the channel
and press L/OUT until L/OUT appears on the display.

To remove the lockout from a channel, manually select the channel and press
L/OUT so L/OUT disappears from the display.

NOTES:  You can still manually select locked-out channels.

        You cannot lock out all channels.  There must be at least one
        active channel in a bank.

PRIORITY

The priority feature lets you scan through the programmed channels and
still not miss an important or interesting call on a specific channel.  To
program a stored channel as the priority channel, press PGM, the desired
channel number, and then PRI.

NOTE:  You can only select one channel as the priority channel.

To turn on the priority feature, press PRI during scanning.  PRI appears on
the display.  The scanner checks the priority channel every 2 seconds, and
stays on the channel if there is activity.  P appears to the left of the
display whenever the scanner is set to the priority channel.

To turn off the priority feature, press PRI during scanning until PRI
disappears from the display.

SPEED

Press SPEED while scanning/searching to alternate between low and high
speeds.  You can scan at either 8 or 25 channels per second, and search at
either 8 or 50 frequencies per second.

A GENERAL GUIDE TO SCANNING

Reception of the frequencies covered by the scanner is mainly "line-of
-sight".  That means you usually cannot hear stations that are beyond the
horizon.

During the summer months, you might be able to hear stations in the 30-50
MHz range located several hundred or even thousands of miles away.  This
is because of summer atmospheric conditions.  This type of reception is
unpredictable but often very interesting!
