X. CTCSS / DCS Tone Signaling
CTCSS and DCS Tones prevent the radio from hearing
signals unless they match coded tones in your radio.
When a
received
signal has a code that matches your
code, squelch will open and you will hear the signal.
When a received signal has a code different from the
one set up in your radio, squelch will not open and
you will not hear the signal.
When you
transmit
on a channel set up with CTCSS
or DCS, the receiving radio must have a matching
code in order to hear your signal.
CTCSS Tones are selected from 38 standard and 11
non-standard tone signaling codes. Refer to the "CTCSS
and DCS Tone Signaling" tables on the following pages.
Change the CTCSS or DCS tone signaling format by
using these steps:
1. With the radio powered on, press the MODE button
two times or until the tone indicator begins to
flash to activate the CTCSS / DCS tone mode.
2. Press the UP (
