Basic Operation

Turning on the Scanner and Setting Squelch

1. Turn SQUELCH counterclockwise until the indicator points to MIN before
you turn on the scanner.

you might hear a hissing sound. Adjust VOLUME to a comfortable listening
level.

NOAA weather station, you should hear weather information.

Notes:
• Make sure the scanner's antenna is connected before you turn it on.
• To listen to a weak or distant station, turn SQUELCH counterclockwise.
• If reception is poor, turn SQUELCH clockwise to cut out weak
transmissions.
• If SQUELCH is adjusted so you always hear a hissing sound, the scanner
will not scan or search properly.

Programming Known Frequencies into Channels

1. Press PGM. PGM appears. Enter the channel number (1–200) where you
want to store a frequency, then press PGM again.
2. Use the number keys and • to enter the frequency (including the decimal
point).
. Press ENT to store the frequency into the channel.
4. To program the next channel in sequence, press PGM and repeat Steps 2
and 3.
n
Notes:
• If you made a mistake entering the frequency, Error appears and the
scanner beeps three times when you press ENT. Start again from Step 2.
• Your scanner automatically rounds the entered frequency down to the
closest valid frequency. For example, if you enter a frequency of 151.473,
your scanner accepts it as 151.470.
• If you entered a frequency that is already stored in another channel, the
scanner beeps three times and displays -dUPL- (duplicate) and the lowest
channel number where the frequency is already stored. Press ENT if you still
want to store the frequency. Press TUNE/CLEAR to cancel.
• Press •/DELAY to set a two-second delay on this channel. The scanner stores
this setting in the channel.
