TONE FREQUENCY ID SCAN

This function scans through all tone frequencies to
identify the incoming tone frequency on a received
signal. You may find this useful when you do not know
the tone frequency that the repeater uses.
1 While the Tone function is ON (" " is visible), press
and hold [AGC/T (SEL)].
2 Press [SCAN (SG.SEL)] to activate the Tone
frequency ID scan.

When the tone frequency is identified, the
transceiver stops scanning and the identified
frequency is displayed.
[SCAN (SG.SEL)] or [CLR] to stop
scanning while the tone frequency ID scan is
active.
[SCAN (SG.SEL)] again to resume
scanning.
Note: Received signals are audible while scanning is in
progress.

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.
A CTCSS tone is sub-audible and is selectable from
among the 42 tone frequencies. Select the same
CTCSS tone as the other stations in your group. You
will not hear calls from stations other than those using
the same CTCSS tone.
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 split-frequency operation, select FM mode on
both VFOs to use CTCSS.
◆
You can select a CTCSS frequency independent of a tone
frequency.
◆
You cannot use the CTCSS function with the Tone function.

CTCSS FREQUENCY ID SCAN

This function scans through all CTCSS frequencies to

recall the CTCSS frequency that the other persons in
your group are using.
