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. Separate
tone frequencies can be set for repeater and tone squelch/
pocket beep operation.
D
Reverse tone/DTCS squelch
The reverse tone/DTCS squelch is convenient if you want to
ignore a specific signal. The transceiver mutes the squelch
when a signal with the matched tone or code is received.
“T SQL-R” / “DTCS-R” is displayed when the reverse tone/
DTCS squelch is set.
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
transceiver.
