CONTINUOUS TONE CODED SQUELCH SYSTEM (CTCSS)

You may sometimes want to hear calls from only 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 the 38 standard tone frequencies.

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

Received

CTCSS freq.: 82.5 Hz

USING CTCSS

1Press the left or right [BAND SEL] to select band A or B.

If necessary, press [F], then the same [BAND SEL] to recall the sub-band.

2Press [TONE] to activate the CTCSS function.

“CT” appears when the CTCSS function is ON.

Each press of [TONE] changes the selection as Tone –> CTCSS –> DCS –> No selection.

3Press [F], [T.SEL].

• The current CTCSS frequency appears and blinks.

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

The selectable frequencies are the same as for the tone frequency. See the table given in “Selecting a Tone Frequency” {page 30}.

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 the appropriate CTCSS frequency.
