■ Tone frequency and DTCS

code

D Subaudible (repeater) tone

Some repeaters require subaudible tones to be accessed.
Subaudible tones are superimposed over your normal signal
and must be set in advance.

D Tone and DTCS squelches

The tone squelch (CTCSS) or DTCS squelch opens only
when receiving a signal containing a matching subaudible
tone or DTCS code, respectively. You can silently wait for
calls from group members using the same tone or code. Sep-
arate tone frequencies can be set for repeater and tone
squelch/pocket beep operation.

D Pocket beep

These functions use 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 trans-
ceiver.
