4 ADVANCED FUNCTIONS
© Tone scan
The transceiver can detect the subaudible tone frequency in a
received signal. By monitoring a signal, such as that being
transmitted on a repeater input frequency, you can determine
the tone frequency required to access the repeater.
@ Push [VFO] to select VFO mode.
* Tone scan cannot be used in memory mode.
@ Set the desired frequency to be checked for a tone fre-
quency.
@® Push [FUNC] + [OT/TSQL] until "TSQL" appears.
@ Push [FUNC] + [(Loaem)T SCAN] to start the tone scan.
* To change the scanning direction, rotate [DIAL].
* Be sure the pager or code squelch is not activated in advance
(pgs. 27, 28).
@® When the tone frequency is matched, the squelch opens
and the tone frequency is programmed into the VFO.
© Push [(vFo)CLR] to stop the scan.
Subaudible tone
frequencies flash as 7
they are scanned.
"TO" appears
during tone scan
© Pocket beep operation
This function uses subaudible tones for calling and can be
used as a "common pager' to inform you that someone has
called while you were away from the transceiver.
® Set the operating frequency.
@ Set the desired subaudible tone in set mode.
* See p. 39 for a list of available tones and p. 15 for programming.
@ Push [FUNC] + [OT/TSQL] until "TSQL ((+))" appears.
* The pocket beep function cannot be used in combination with the
pager or code squelch (pg. 27, 28).
@ When a signal with a matched tone is received, the trans-
ceiver emits beep tones for 30 sec. and flashes
"TSQL ((+))."
® Push [PTT] to answer or push [(vFo)CLR] to stop the beeps
and flashing.
* Tone squelch is automatically selected.
© Calling a waiting station using pocket beep
A subaudible tone matched with the station's tone frequency
is necessary. Use the tone squelch on p. 30 or a subaudible
tone encoder.
