Privacy Codes
Your radio incorporates two advanced coded squelch systems that can help to
reduce interference from other users on any given channel. CTCSS (Continuous
Tone Coded Squelch System) provides 38 privacy codes and DCS (Digitally
Coded Squelch) provides privacy codes for factory default channel preset. The
CTCSS (Continuous Tone Coded Squelch System) can be used on all channels.
For ease of use and to reduce interference from other users, the 22 channels
of your radio have been customized, see Channel and Default Privacy Code
Table .
10 11
The privacy code OFF is not a privacy code, but allows all signals
to be heard on a channel that is set to 0 on both the CTCSS and
DCS systems.
See Page 12 for resetting all the channels and privacy code
setting to factory default.
You can change your radio Privacy Codes in order to work with
other radios with different privacy codes or radio without
privacy codes. See page 11 and 12 for procedures.
To successfully communicate using a privacy code, both the
sending and receiving radios must be tuned to the same channel
and to the same privacy code number (CTCSS or DCS). Each
channel will remember the last privacy code system and number
you select.
