Programming The Scanner

Follow these steps to program frequencies into your scanner.

1.  Repeatedly press PGM until the number of the channel you want to program
    appears on the display.

2.  Enter a frequency.

    An excellent reference for active frequencies is Radio Shack's Police
    Call Radio Guide including Fire and Emergency Services.  We update this
    directory every year, so be sure to get a current one.  Also, refer to
    "A General Guide to Scanning" in this manual.

3.  Press ENTER to store the frequency you entered in Step 2.

    If you enter an invalid frequency, ERROR appears on the display.  Press
    CLEAR and repeat Step 2.

4.  If you want the scanner to pause at the end of each transmission, before
    it continues scanning, press DELAY so that a dot appears after the chan-
    nel number.

    If you do not want the scanner to pause, press DELAY so that the dot
    disappears from the display.

5.  Press PGM to program the next channel.

    Repeat Steps 2 - 5 to store additional frequencies (up to 10).

Setting The Volume and Squelch

Follow these steps to set the volume and squelch.

1.  Turn VOLUME and SQUELCH fully counterclockwise.

2.  Turn VOLUME clockwise until you hear a hissing sound.

3.  Slowly turn SQUELCH clockwise until the hissing stops.

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

Scanning The Channels

After you store frequencies, press SCAN to scan the channels for a trans-
mission.  The scanner quickly scans the channels until it finds a trans-
mission.  When the transmission ends, the scanner resumes scanning.

NOTE:  If you hear hissing between transmissions and the scanner does not
       scan, adjust SQUELCH.

Manually Selecting A Channel

To stop scanning and listen to a single channel, press MANUAL.  Then, press
the channel number you want to listen to.

Locking Out A Channel

You can lock out channels you do not want to monitor, such as a continuously
transmitted weather channel.  To do so, follow these steps.

1.  Press MANUAL.  MANUAL appears above the channel number.

2.  Enter the channel number you want to lock out.

3.  Press L/OUT.  L appears to the right of the channel number.

The scanner now skips the locked-out channel when it scans, but you can
still manually select the locked-out channel.  (See "Manually Selecting A
Channel")

To unlock a channel, select the channel and press L/OUT so that L dis-
appears.

Locking The Keypad

Once you program your scanner, you can protect it from accidental program
changes by pressing KEY LOCK.  A dash (-) appears on the display.  In this
mode, the only controls that operate are LIGHT, VOLUME, SQUELCH, SCAN and
MANUAL.

When you want to change the scanner's programming, press KEY LOCK again so
that the dash (-) disappears from the display.

Lighting The Display

Press LIGHT to help you identify settings in the dark.
