ACTIVATING SCAN FUNCTIONS
ACTIVATING SCAN FUNCTIONS
The F-20 has two scan modes. The most popular and most used is the
“BUSY”
channel scan.
This allows the radio to stop on a channel that someone is talking on.
When the radio stops on a “Busy” channel, the scan will stop and resume after about 5 seconds.
The other is
“DUAL WATCH”
. This allows you to scan only two channels. This is useful when
you want to keep track of two other people.
Busy Channel Scan:
1. Press and release the
”F”
button the ”SCAN” icon (5) will begin flashing.
2. Press and release the
“UP”
or
“DOWN”
channel button to activate scan. The unit will now
begin scanning through the channels.
Pressing the
“UP”
or
“DOWN”
channel button during scan will determine if the channels
are scanned up or down.
Pressing the
“PTT”
(push to talk) button will cause the radio to stop scanning and return
to normal operate mode.
ACTIVATING DUAL WATCH
Activating Dual Watch
Dual watch is a function that allows you to scan only two channels.

2. Press
the
“F”
button three times until
“DW”

3. Select the second channel to be scanned.

switching between the two channels.
When the radio hears activity on either channel, scanning will stop on that channel for
about 5 seconds and then resume scanning.

“PTT”
button.
This will deactivate Dual Watch and allow you to communicate normally.
