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.
5 Press [ESC] to exit.
SELECTING THE CROSS TONE
“Cross Tone” is a function used when you are
communicating via a repeater that requires different tones
for your transmission (uplink) to the repeater and for your
reception (downlink) from the repeater.
Cross tone uses the tone frequency for the transmission
and the CTCSS frequency for the reception. The CTCSS
frequency activates the tone squelch at the time of signal
reception and the tone is sent at the preset tone frequency
at the time of signal transmission.
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 CROSS.
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 "TX" LED and "RX" LED for the sub band turn Off, "TONE",
"CT", and "CROSS" will also be grayed out.
