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 using the same tone in an amateur band while you
were away from the receiver.
D Waiting for a call from a specific station
q Set the operating frequency.
w Set the desired tone squelch tone in expanded set mode.
•See the previous page for programming information.
e Push [V/M] for 2 sec. to enter expanded set mode.
r Rotate [DIAL] until “TSQL” appears.
•Turn the expanded set mode ON for selection. (p. 25)
•“TSQL” 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.
•“TSQL ë” appears in the function display.
u When a signal with the correct tone is received, the re-
ceiver emits beep tones for 30 sec. and flashes “ë.”
i Push [V/M] to stop the beeps and flashing.
•Tone squelch is automatically selected.
The receiver has 50 tone frequencies and consequently
their spacing is narrow compared with units having 38
tones. Therefore, some tone frequencies may receive in-
terference from adjacent tone frequencies.
■ Tone scan
The receiver can detect the subaudible tone frequency in a
received signal. By monitoring a signal that is being transmit-
ted on a frequency, you can check the tone frequency re-
quired to access the repeater or to open the tone squelch.
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 tone squelch fre-
quency.
•“Ct” appears during tone scan.
r Push [FUNC] + [Y] or [Z] to stop the scan.
