7 ENHANCED COMMUNICATIONS
FM CTCSS OPERATION
You may sometimes want to hear calls only from specific persons. When using FM mode, the Continuous Tone Coded Squelch System (CTCSS) allows you to ignore (not hear) unwanted calls from other persons who are using the same frequency.
ACTCSS tone is
Note: CTCSS does not cause your conversation to be private. It only relieves you from listening to unwanted conversations.

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 7 and 8 if you have already programmed the appropriate CTCSS frequency.
Note:
◆When using
◆You can select a CTCSS frequency independent of a tone frequency.
◆You cannot use the CTCSS function with the Tone function.
7While “CT” is visible, press [NB/T/ 7] (1 s).
•The current CTCSS frequency appears. The default CTCSS frequency is 88.5 Hz.
8Turn the MULTI control to select the appropriate CTCSS frequency.
•The selectable CTCSS frequencies are listed in the following table.
9Press [MTR/ CLR] to complete the setting.
CTCSS FREQ. ID SCAN
This function scans through all CTCSS frequencies to identify the incoming CTCSS frequency on a received signal. You may find this useful when you cannot recall the CTCSS frequency that the other persons in your group are using.
1While the CTCSS function is ON, press [NB/T/ 7] (1 s).
•The current CTCSS frequency appears.
2Press [SCAN/ SG.SEL] to activate the CTCSS frequency ID scan.
•While the transceiver is receiving a signal, “CT” blinks and every CTCSS frequency is scanned. When the CTCSS frequency is identified, the transceiver stops scanning and the identified frequency is displayed.
•Press [SCAN/ SG.SEL] again to resume scanning.
•Press [SCAN/ SG.SEL] to stop scanning while the CTCSS frequency ID scan is active.
Note: Received signals are audible while scanning is in progress.
