Tone Squelch And Pocket Beep; Tone/Dtcs Squelch And Pocket Beep - Icom ic-U80 Instruction Manual

■ Tone/DTCS squelch and pocket beep

D Tone squelch and DTCS squelch
The tone squelch (CTCSS) or DTCS squelch opens only
when receiving a signal that includes a matched CTCSS tone
or DTCS code, respectively. You can silently wait for calls
using the same tone or code. Separate tone frequencies can
be set for repeater and tone squelch/pocket beep operation.
D Pocket beep
The pocket beep function uses subaudible tones or DTCS
codes for calling, and can be used as a "common pager" to
inform you that someone has called while you were away
from the transceiver.
