CONTINUOUS TONE CODED SQUELCH SYSTEM (CTCSS)

You may sometimes want to hear calls only from specific persons. The Continuous Tone Coded Squelch System (CTCSS) allows you to ignore (not hear) unwanted calls from other persons who are using the same frequency.

First select the same CTCSS tone as selected by the other persons in your group. A CTCSS tone is subaudible and is selectable from among 38 standard tone frequencies.

Note: CTCSS does not cause your conversation to be private. It only relieves you from listening to unwanted conversations.

4Press [c]/ [d] to select a CTCSS frequency.

•The selectable frequencies are the same as for the tone frequency. Refer to the table in “Selecting a Tone Frequency” {page 28}.

5Press [OK] to complete the setting.

You will hear calls only when the selected tone is received. To answer the call, press and hold Mic [PTT], then speak into the microphone.

Skip steps 3 to 5 if you have already programmed an appropriate CTCSS frequency.
