STORING KNOWN 
FREQUENCIES INTO 
CHANNELS
Good references for active frequencies are 
the RadioShack 
Police Call
, 
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
, enter the channel number 
(1–200) where you want to store a 
frequency, then press 
PGM
 again. The 
channel number appears.
2. Use the number keys and • to enter the 
frequency (including the decimal point) 
you want to store.
3. Press 
ENTER
 to store the frequency into 
the channel.
Notes
:
• If you made a mistake in Step 2, 
Error
 appears and the scanner 
beeps when you press 
ENTER
. 
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 for 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 
ENTER
 again. Press 
MON/CL 
to clear 
the frequency.
• Press 
DELAY
 if you want the scanner 
to pause 2 seconds on this channel 
after a transmission ends before it 
proceeds to the next channel (see 
“Using the Delay Function” on 
Page 20). The scanner also stores 
this setting in the channel.
