OTHER FUNCTIONS

■ Tone scan

The transceiver can detect the subaudible tone frequency and
DTCS code in a received signal. By monitoring a signal that
is being transmitted on a repeater input frequency, you can
determine the tone frequency required to access the repeater.

q Set the desired frequency or memory channel to be

checked for a tone frequency or DTCS code.

w Push and hold [7/DSQ/TONE] for 1 sec. several times to

activate the repeater tone, tone squelch or DTCS squelch.
(TONE, TSQL or DTCS)

• Rotating [DIAL] while pushing and holding [7/DSQ/TONE] also

selects the tone functions.

e Push and hold [9/BK/T.SCAN] for 1 sec. to start the tone

scan.

• To change the scanning direction, rotate [DIAL].

r When the tone frequency or DTCS code is decoded, the

set mode contents are programmed with the frequency or
code.

• The tone scan pauses approx. 10 sec. when a tone frequency

or DTCS code is detected.

• The decoded tone frequency is used for the repeater tone fre-

quency when the tone squelch is OFF.

• The decoded tone frequency is used for the tone squelch fre-

quency when the tone squelch is ON.

• The decoded DTCS code is used for the DTCS code when the

DTCS squelch is ON.

t Push [VFO/MHz] to stop the scan.

• If the scan is cancelled before the transceiver detects the tone or

code, the set mode contents are not changed.
