SELECTING THE CTCSS TONE
Follow the procedure below to change the type of tone
signal after selecting the main band or sub band.
[F1]~[F7]
[FM/AM/FM-N]
1
Press
[FM/AM/FM-N]
to enter FM mode.
2
Press
[TONE]
(F4) to select CTCSS tone.
Each time you press the key, the tone signal display cycles
as follows: CT (CTCSS) > CROSS > deselected; the main
screen display varies as follows: "TONE" > "CT" > "CROSS"
> blank (deselected) > "TONE".
Note:
If the selected band is dedicated for reception ("TX" LED is unlit),
"CT" will be grayed out.
If the "TX" LED and "RX" LED for the sub band turn Off, "TONE",
"CT", and "CROSS" will also be grayed out.
USING THE SCAN TO SEARCH FOR THE CTCSS TONE
FREQUENCY
A tone frequency scan makes it possible to detect the
CTCSS tone frequency contained in the receive signal in
FM mode. This function is convenient if you wish to know
the CTCSS tone frequency of a repeater.
Follow the procedure below after selecting the main band
or sub band.
[F1]~[F7]
[FM/AM/FM-N]
[ESC]
[SQL](M)
[SQL](S)
1
Press
[FM/AM/FM-N]
to enter FM mode.
2
Press and hold
[TONE]
(F4) to open the
FM Tone
Frequency
screen.
3
Press
[
]
(F2) or
[
]
(F3) to select
"CTCSS" as a tone type.
4
Press
[SCAN]
(F7) to scan the CTCSS tone frequency.
Until the scan ends, "SCAN" appears on the right of the
CTCSS tone frequency.
As soon as the CTCSS tone frequency is detected, the
scan stops and the frequency appears in the FREQ. [Hz]
box.
The scan starts with a press of
[M/S]
(F6) while the
transceiver is in reception in the selected band (the "MAIN
BUSY/TX" LED or the "SUB BUSY/TX" LED lights).
If the "MAIN BUSY/TX" LED or "SUB BUSY/TX" LED
is unlit, rotate the
SQL
control to receive so that the
transceiver will be placed in receive mode.
Press
[M/S]
(F6) if you wish to change the current band
(main band or sub band).
The scan pauses by pressing
[SCAN]
(F7) while scanning
the CTCSS tone frequency. The scan resumes by pressing
[SCAN]
(F7) again.
The scan pauses if the receive signal breaks off
while scanning the CTCSS tone frequency. The scan
automatically restarts when the transceiver detects the
receive signal.
