Continuous Tone Coded Squelch System (CTCSS)
This feature allows you to ignore transmissions from other units that are using the same channel. One of 38 privacy codes may be selected. The same code must also be selected on those transceivers with which you desire to communicate. Keep in mind, however, that this feature does not prevent others from listening to your transmissions.
To Select a CTCSS Code
Press the function select button twice or until the small digits on the right flash on the display. Use the up and down buttons to select the desired squelch code number. After 5 seconds, the unit will return to the standby mode. The CTCSS squelch code will be applied only to the currently selected channel. To disable the CTCSS, and allow the transceiver to receive all messages on a particular channel select “00” as the code.
