ACTIVATING “PRIVACY” CODES
To activate “CTCSS” codes
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
