I Tone frequency and DTCS code

• Subaudible (repeater) tone
Some repeaters require subaudible
tones to be accessed. Subaudible
tones are superimposed over your nor-
mal signal and must be set in advance.
• Tone and DTCS squelches
The tone squelch (CTCSS) or DTCS
squelch opens only when receiving a
signal containing a matching subaudi-
ble 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
squelch/pocket beep operation.
• Pocket and DTCS 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. The
same code is used for DTCS squelch
and beep.
