(200-0521)                 Operation                  Faxback Doc. # 48459

TURNING ON THE SCANNER AND SETTING SQUELCH

Note:  Make sure the scanner's antenna is connected before you turn it on.

1.  Turn SQUELCH fully counterclockwise.

2.  Turn VOLUME/OFF clockwise until it clicks and you hear a hissing sound.

3.  Press MAN (manual) to stop the scanner from scanning and turn SQUELCH
    clockwise, then leave it set to a point just after the hissing sound
    stops.

STORING KNOWN FREQUENCIES INTO CHANNELS

Good references for active frequencies are RadioShack's "Beyond Police
Call," "Aeronautical Frequency Directory," and "Maritime Frequency
Directory."  We update these directories every year, so be sure to get a
current copy.

Follow these steps to store frequencies into channels.

1.  Press MAN, enter the channel number where you want to store a
    frequency, then press PROG.  The channel number appears.

2.  Use the number keys and (symbol) to enter the frequency (including the
    decimal point) you want to store.

3.  Press E to store the frequency into the channel.

    Notes:  If you entered an invalid frequency in Step 2.  Error appears
            and the scanner beeps three times.  Simply enter the frequency
            again.

            Your scanner automatically rounds the entered frequency to the
            nearest valid frequency.  For example, if you enter a
            frequency of 151.473, your scanner accepts it as 151.475.

            Press DELAY if you want the scanner to pause 2 seconds after a
            transmission ends before it proceeds to the next channel (see
            "Delay" in Faxback Doc. # 48460).  The scanner also stores
            this setting in the channel.

4.  If you want to program the next channel in sequence, press PROG and
    repeat Steps 2 and 3.

SEARCHING FOR AND TEMPORARILY STORING ACTIVE FREQUENCIES

If you do not have a reference to frequencies in your area, use a limit,
direct, or service search to find a transmission.  Also see "Guide to the
Action Bands" in Faxback Doc. # 17653.

Notes:  While doing a limit, direct, or service bank search, you can
        press:

           DELAY if you want the scanner to pause 2 seconds after a
           transmission ends before it proceeds to the next frequency (see
           "Delay" in Faxback Doc. # 48460).

           DATA if you want the scanner to skip data signals (such as fax
           or modem signals) and search only for audio (voice) signals
           (see "Skipping Data Signals" in Faxback Doc. # 48460).

Limit Search

A limit search lets you search within a specific range of frequencies.
-L- appears during a limit search.

1.  Press PROG, then LIMIT.  Lo and 29.000 MHz appear.

2.  Enter the frequency that is the lower limit of the range you want to
    search (including the decimal point), then press E.

3.  Press LIMIT.  Hi and 956.000 MHz appear.

4.  Enter the frequency that is the upper limit for the range you want to
    search (including the decimal point), then press E again.

5.  Press [\/] to search from the upper to the lower limit, or [/\] to
    search from the lower to the upper limit.

8.  When the scanner stops on a transmission, quickly press either:

       HOLD to stop searching so you can listen to the transmission.  HOLD
       appears.

       MON/CLEAR to store the displayed frequency into the current monitor
       memory.

    To release hold and continue searching, press HOLD or hold down [\/]
    or [/\] for at least 1 second.  Or, if you did not press HOLD, simply
    press [\/] or [/\] to continue searching.

Direct Search

Direct search lets you search up or down from the currently displayed
frequency.

1.  Press MAN.

2.  Use the number keys to enter the frequency you want to start the
    Search from.  Press ( . ) to enter a decimal point.

    Notes:  If you want to start the search from a frequency already
            stored in one of your scanner's channels, press MAN or PROG,
            use the number keys to enter the channel number, then press
            MAN or PROG again.

            If you enter an invalid frequency, the scanner displays Error.
            Simply repeat this step.

3.  Press [\/] to search downward or [/\] to search upward from the
    selected frequency.  -d-, SEARCH, and [\/] or [/\] appear.

4.  When the scanner stops on a transmission, quickly press either:

       HOLD to stop searching so you can listen to the transmission.  HOLD
       appears.

       MON/CLEAR to store the displayed frequency into the current monitor
       memory.

    To release hold and continue searching, press HOLD or hold down [\/]
    or [/\] for at least 1 second.  Or, if you did not press HOLD, simply
    press [\/] or [/\] to continue searching.

    Note:  To step through the frequencies while HOLD is displayed, press
           [\/] or [/\].

Service Bank Search

You can search for weather, ham, marine, aircraft, or police (fire/
emergency) transmissions even if you do not know the specific frequencies
being used in your area.  The scanner is preprogrammed with all the
frequencies allocated to these services.  To use this feature, press SVC.
SVC appears and the scanner searches through the weather service band.  To
select a different service bank, press the desired service bank key (WX1,
HAM2, MRN3, AIR4, or POL5).  The corresponding service band number (-1-,
-2-, -3-, -4-, or -5-) appears, and the scanner starts searching the band.

When the scanner stops on a transmission, quickly press either:

    HOLD to stop searching so you can listen to the transmission.  HOLD
    appears.

    MON/CLEAR to store the displayed frequency into the current monitor
    memory.

    To release hold and continue searching, press, HOLD or hold down [\/]
    or [/\] for at least 1 second.  Or, if you did not press HOLD, simply
    press [\/] or [/\] to continue searching.

Note:  Because there are many different frequencies allocated to fire and
       police department, it takes several minutes to search all these
       frequencies.

Search Skip Memory

You can skip up to 20 specified frequencies during a limit or direct
search and up to 20 specified frequencies during a service bank search.
This lets you avoid unwanted frequencies or ones you have already stored
in a channel.

To skip a frequency, press S/S when the scanner stops on the frequency
during a limit, direct, or service search.  The scanner stores the
frequency in memory and automatically resumes the search.

To clear a single frequency from skip memory so the scanner once again
stops on it during a limit, direct, or service bank search:

1.  Press HOLD to hold the search.

2.  Press [\/] or [/\] to select the frequency.  L/O appears.

3.  Press S/S.  L/O disappears.

To clear all the skip frequencies at once while searching, press HOLD,
then hold down S/S until the scanner beeps twice (about 3 seconds).

Notes:  If you marked all frequencies to be skipped within the search
        range, the scanner beeps 3 times and does not search.

        If you program more than 20 frequencies to skip, each new
        frequency replaces one you already stored, starting from the first
        frequency you stored.

        Press [\/] or [/\] to select a skipped frequency while HOLD
        appears.  L/O appears when you select a skipped frequency.

LISTENING TO THE MONITOR MEMORIES

You can listen to the frequency you stored in any one of the five monitor
memories by pressing MAN, MON/CLEAR, then the number of the monitor memory
you want to listen to (1-5).

Note:  To listen to the monitor memories, the priority channel feature
       must be turned off (see "Priority" in Faxback Doc. # 48460).

MOVING A FREQUENCY FROM A MONITOR MEMORY TO A CHANNEL

1.  Press MAN.  MAN appears.

2.  Enter the number of the channel where you want to store the frequency
    in a monitor memory, then press PROG.  PGM appears.

3.  Press MON/CLEAR and enter the number of the monitor memory that
    contains the frequency you want to store.

4.  Press E.  The scanner stores the frequency into the selected channel.

SCANNING THE STORED CHANNELS

To begin scanning channels, press SCAN.  The scanner scans through all
non-locked channels in the activated banks.  (See Locking Out channels" in
Faxback Doc. # 48460 and "Turning Channel Storage Banks On and Off" in
Faxback Doc. # 48460).  When the scanner finds a transmission, it stops on
it.  When the transmission ends, the scanner resumes scanning.

Notes:  If you have not stored frequencies into any channels, the scanner
        does not scan.

        If the scanner picks up unwanted, partial, or very 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 counterclockwise.

        If SQUELCH is adjusted so you always hear a hissing sound, the
        scanner does not scan properly.

        To scan in the trunk tracking mode, see "Scanning a Trunked Bank"
        in Faxback Doc. # 48461.

MANUALLY SELECTING A CHANNEL

You can continuously monitor a single 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 specific channel.

Follow these steps to manually select a channel.

1.  Press MAN.

2.  Enter the channel number.

3.  Press MAN again.

Or, if your scanner is scanning and stops at the desired channel, press
MAN one time.  (Pressing MAN additional times causes your scanner to step
through the channels.)

To resume automatic scanning, press SCAN.
