I 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.
