OWNER'S MANUAL FOR THE F-20 (FRS W/532 CODES)
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
Dual watch is a function that allows you to scan only two channels.
1. Select channel one.
2. Press the "F" button three times until "DW" (11) is flashing.
3. Select the second channel to be scanned.
About 1 second after your selection of the second channel is complete the radio will begin
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.
If communication is desired on the channel scanning stopped on, press the "PTT" button.
This will deactivate Dual Watch and allow you to communicate normally.
To reactivate Dual Watch repeat steps above.
Activating the "CTCSS" code will prevent you from hearing any conversation that is not
using the same "CTCSS" code. This does not make your conversation private.
1. Press the "F" button twice to cause the icon "CTCSS" to be displayed in the upper left of the
display to flash.
2. Press and release the "UP" or "DOWN" buttons to select the "CTCSS" code you desire.
3. Press "ENTER" to store the code setting for that channel.
A code of "oF" means no code is programmed.
You must do this for each of the channels you want CTCSS codes on.
Activating the "CTCSS" code will prevent you from hearing any conversation that is not
using the same "CTCSS" code. This does not make your conversation private.
4.
If you wish to set another channel for CTCSS code, choose a different code than the ones
in use.
The following is a list of frequencies of the CTCSS codes. Different brands of radios may use a
different number code for the frequencies. For operation with other brands of radios the selected
CTCSS frequency must match.
