Setting Volume and Squelch

Follow these steps to set VOLUME and SQUELCH.

1.  Rotate VOLUME 1/4 turn clockwise and SQUELCH fully clockwise.

2.  Slowly turn SQUELCH counterclockwise until you hear a hissing sound.

3.  Slowly turn SQUELCH clockwise until the hissing stops.

NOTE:  If you want to listen to a weak or distant station, turn SQUELCH
       counterclockwise.  You might hear hissing between transmissions.


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

To turn on the KEYLOCK feature, press K/L until KEYLOCK appears on the

To turn it off, press K/L until KEYLOCK disappears.

Storing Frequencies

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

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

2.  Press PROG. PGM appears on the display to indicate the scanner is in
    the programming mode.

3.  Enter a frequency.

4.  Press ENTER to store the frequency.

If you made a mistake in Step 3, Error appears on the display and the
scanner sounds three beeps. To clear the display, press CLEAR. Then proceed
again from Step 3.

NOTE: If you want to program the next channel in sequence, repeat Steps
      2 - 4.

5.  Repeat Steps 1 - 4 to program more channels.

Searching For and Temporarily Storing Active Frequencies

Good references for active frequencies are Radio Shack's "Police Call 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.

If you do not have a reference to frequencies in your area, use a limit or
direct search to find a transmission.  Also see "A Guide to the Action

NOTE:  Press DELAY if you want to make the scanner pause 2 seconds after a
       transmission ends before it proceeds to the next frequency.

Limit Search

Limit search lets you search within a specific range of frequencies.  -L-
appears on the display during a limit search.

1.  Press PROG, then LIMIT. Lo appears on the display.

2.  Enter the lower limit of the frequency range you want to search.

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

4.  Enter the upper limit of the frequency range.

5.  Press ENTER.

6.  Press \/ to search from the upper to the lower limit or press /\ to
    search from the lower to the upper limit.

7.  When the scanner stops on a transmission, press MONI to store the freq-
    uency into the current monitor memory, or press /\ or \/ to continue the

Direct Search

Direct Search lets you  search up or down from the currently displayed  frequency.  -d- appears on the display during a direct search.

1.  Press MANUAL, the channel number and MANUAL in sequence to select a
    frequency stored in a channel.

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

3.  When the scanner stops on a transmission, press MONI to store that
    frequency in the current monitor memory.  Or, press /\ or \/ to con-
    tinue the search.

Using the Band Search Keys

You can search for air, fire, marine, or weather transmissions even if you
do not know the frequencies being used in your area.  The scanner is pro-
grammed with all frequency ranges allocated to these services.  To use this
feature, press BAND.  Then press the desired service band key (AIR, FIRE,
MARINE or WX).  The scanner starts searching the band.

When the scanner stops on a transmission, you can store that frequency into
the monitor memory by pressing MONI.

To continue scanning, press /\ or \/.

NOTES:  To make the scanner pause 2 seconds after a transmission before
        proceeding to the next frequency, press ./DELAY until DLY appears.
        See "Delay."  The delay feature is programmed band by band in this

        The 800 and 900 MHz bands are allocated to Trunked services.  This
        means that the police and fire departments share the frequencies
        with other services.  The scanner might stop on transmissions by
        other services in these bands.

        Because there are many different frequency ranges allocated to fire
        and police departments, it takes several minutes to search all
        frequencies when you scan for these services.

Listening To Monitor Memories

You can listen to a monitor memory by pressing MANUAL, MONI, and then the
number of the monitor memory you want to listen to.

NOTE:  Turning off the scanner clears the frequencies stored in the monitor

Moving a Frequency From A Monitor Memory To A Channel

To begin scanning the channels, press SCAN.  The scanner scans through all
non-locked channels in the activated banks.  Set SQUELCH so you do not hear
the hissing sound between transmissions.  (See "Locking Out Channels" and
"Turning Channel-Storage Banks On and Off.)"
