SETTING VOLUME AND SQUELCH

1.  Turn VOLUME clockwise and SQUELCH counterclockwise until you hear a
    hissing sound.

2.  Adjust VOLUME to a comfortable level.

3.  Slowly turn SQUELCH clockwise until the noise stops.

If the scanner picks up unwanted weak transmissions, rotate SQUELCH
clockwise to decrease the scanner's sensitivity to these signals.

USING THE KEYLOCK

Once you program your scanner, you can protect it from accidental program
changes by turning on the keylock feature.  In this mode, the only
controls that operate are SCAN, MANUAL, LIGHT, VOLUME and SQUELCH.

To turn on the keylock, press KEYLOCK until K flashes on the display.  To
turn it off, press KEYLOCK so that K disappears from the display.

5.  If you want the scanner to pause for 2 seconds after each transmission
    before it proceeds to the next channel, press ./DLY until D appears
     the display.

    the next channel in sequence, repeat Steps 2-5.


SEARCHING FOR AND TEMPORARILY STORING ACTIVE FREQUENCIES

Good references for active frequencies are Radio Shack's "Police Call
Guide Including Fire and Emergency Service's," "Official Aeronautical
Frequency Directory."  We update these directories every year, so be sure
to get a current copy.

If you do not have a reference to frequencies in your area, search to
find a transmission.

1.  Press MANUAL or PGM.  Enter the frequency from which you want to start
    your search.

Or, press MANUAL, a channel number, and MANUAL or PGM to select the
channel from which you want to start your search.

2.  Press /\ or \/ to search up or down from the displayed frequency.

3.  When the scanner stops on a transmission, press 0/MON to store the
    frequency in the monitor memory, or press /\ or \/ to continue the
    search.

Note:  Press ./DLY to make the scanner pause 2 seconds after a
       transmission before it proceeds to the next frequency.

LISTENING TO THE MONITOR MEMORY

You can listen to the monitor memory by pressing MANUAL and then 0/MON.

MOVING A FREQUENCY FROM THE MONITOR MEMORY TO A CHANNEL

1.  Press MANUAL.  Enter the channel number into which you want to store
    the monitor frequency.

2.  Press PGM.

3.  Press 0/MON.  The channel indicator flashes.

4.  Press L-OUT/ENT.  The scanner stores the monitor frequency in the
    channel, and the channel indicator stops flashing.

SCANNING THE CHANNELS

To begin scanning the channels in your scanner, press SCAN.  The scanner
scans through all non-locked channels.  Set SQUELCH so your do not hear
the hissing sound between transmissions.
