SUBAUDIBLE TONE OPERATION
■
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.
D
Waiting for a call from a specific station
q
Set the operating frequency.
w
Set the desired CTCSS tone in set mode.
• See the previous page for programming information.
e
Push [V/M] for 2 sec. to enter set mode.
r
Rotate [DIAL] until “T/TSQL” appears.
• “T/SQL” disappears after 1 sec. and “tO” appears.
t
While pushing [FUNC], rotate [DIAL] to select “P BEEP.”
y
Push [V/M] to exit set mode and start the pocket beep.
• “T SQL
ë
” appears in the function display.
u
When a signal with the correct tone is received, the trans-
ceiver emits beep tones for 30 sec. and flashes “
ë
.”
i
Push [PTT] to answer or push [V/M] to stop the beeps and
flashing.
• Tone squelch is automatically selected.
D
Calling a waiting station using pocket beep
A subaudible tone matched with the station’s tone frequency
is necessary. Use the tone squelch on the previous page or a
subaudible tone encoder.
■
Tone scan
The transceiver can detect the subaudible tone frequency in a
received signal. By monitoring a signal that is being transmit-
ted 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.
w
Push [FUNC] + [
Y
] or [
Z
] for 2 sec. to start the tone scan.
• To change the scanning direction, rotate [DIAL].
e
When the tone frequency is decoded, the set mode con-
tents are programmed with the tone frequency.
• The tone scan pauses when a tone frequency is detected.
• The decoded tone frequency is used for the repeater tone fre-
quency or tone squelch frequency, depending on the the tone
squelch ON/OFF setting.
• “Ct” or “Rt” appears during tone scan when the tone squelch is in
use or not.
r
Push [FUNC] + [
Y
] or [
Z
] to stop the scan.
T
“Rt” or “Ct” appears
during tone scan.
Subaudible tone
frequencies flash as
they are scanned.
