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 38 standard 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.
1 Press [A/B] to select VFO A or VFO B.
•“tA” or “tB” appears to show which VFO is
selected.
2 Select a band.
3 Select an operating frequency.
4 Press [FM/ AM/ NAR] to select FM mode.
• “FM” appears.
5 Turn the SQL control to adjust the squelch.
6 Press [6/ CTCSS/SEL] to switch the CTCSS
function ON (or OFF).
• “C T” appears when the function is ON.
7 Press [FUNC], [6/ CTCSS/SEL].
• The current CTCSS frequency appears. The
default CTCSS frequency is 88.5 Hz.
8 Turn the MULTI/ CH control to select the
appropriate CTCSS frequency.
• The selectable CTCSS frequencies are listed in
the following table.
9 Press [FUNC], [6/ CTCSS/SEL] to complete the
setting.

You will hear calls only when the selected tone is
received. To answer the call, press [SEND] or 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.
◆
Use Nos. 01 to 38 shown in the table above when selecting
CTCSS frequencies via Wireless Remote Control {page 82}.
◆
You can select a CTCSS frequency independent of a tone
frequency.
◆
You cannot use the CTCSS function with the Tone or DCS
functions.
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.
1 Press [FUNC], [6/ CTCSS/SEL].
• The current CTCSS frequency appears.
2 Press [SCAN/ SG.SEL] to activate the CTCSS
Freq. ID scan.
• “C T” blinks and every CTCSS tone 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 tone frequency ID scan is active.
Note: Received signals are audible while scanning is in progress.
