2. Use the number keys and
•
to enter the frequency (includ-
ing 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 fre-
quency down to the closest valid frequency. For exam-
ple, 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 dis-
plays 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
MON/CL
to clear the frequency.
• Press
DELAY
if you want the scanner to pause 2 sec-
onds on this channel before it proceeds to the next
channel after a transmission ends (see “Delay” on
Page 42). 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.
FINDING AND STORING ACTIVE
FREQUENCIES
Searching the Service Banks
Your scanner contains groups of preset frequencies called ser-
vice banks. Each service bank is associated with a specific ac-
tivity (see “Service Banks” on Page 21). You can search for
fire/police, air, ham, auto race, and marine transmissions even
if you do not know the specific frequencies that are used in
your area. Then you can store the frequencies you found into
the scanner’s channels or monitor memories.
