SQUELCH clockwise to cut out weak transmissions.
• If

STORING KNOWN FREQUENCIES INTO CHANNELS
Good references for active frequencies are the RadioShack 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.
Follow these steps to store frequencies into channels.
1. Press PGM, then 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) you want to store.
3. Press
ENT to store the frequency into the channel.
Notes:
• If you made a mistake in Step 2,
Error
appears and the scanner beeps three times when you
press
ENT. Simply 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 the lowest channel number where the frequency is already stored, and
–dUPL–
then
the frequency flashes. If you want to store the frequency anyway, press
ENT again. Press
TUNE/CLEAR to clear the frequency.
• Press
DELAY if you want the scanner to pause 2 seconds on this channel before it proceeds to the
next channel after a transmission ends (see “Delay” on Page 20). The scanner also stores this
setting in the channel.
4. To program the next channel in sequence, press
PGM and repeat Steps 2 and 3.
