SUBAUDIBLE TONE OPERATION
■ 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.
➀ Set the desired frequency or memory channel to be
checked for a tone frequency.
➁ Push [
f
(T-SCAN)] for 1 sec. to start the tone scan.
• Push [Y]/[Z] to change the scan direction.
➂ When the tone frequency is decoded, the set mode con-
tents are programmed with the tone frequency.
• The decoded tone frequency is used for the tone encoder or tone
encoder/decoder, depending on the tone squelch on/off setting.
•“Ct” (CTCSS—Continuous Tone Coded Squelch System) or “Rt”
(Repeater Subaudible Tone) appears during tone scan whether
the tone squelch is in use or not.
➃ Push [
f
(T-SCAN)] again to stop the 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 you while you were away from the transceiver.
➀ Set the operating frequency.
➁ Set the desired subaudible tone (same as that used for
tone squelch operation, “Ct”) in set mode.
• See previous page for programming.
➂ Push [C T] two times until “TSQLS” appears.
➃ When a signal with a matched tone is received, the trans-
ceiver emits beep tones for 30 sec. and flashes “S.”
➄ Push [PTT] to answer or push [ ] 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
subaudible tone encoder (p. 15).
