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 39 privacy codes and DCS (Digitally
Coded Squelch) provides 168 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 5 channels of
your radio have been customized, see
Channel and Default Privacy Code
Table .

See Page 14 for frequency allocations charts.
Both radios must be tuned to the same channel to communicate.
See Page 10 for resetting all the channels and privacy code
setting to factory default.
The privacy code OFF is not a privacy code, but allowing all
signals to be heard on a channel that is set to 0 on both the
CTCSS and DCS systems.
See Page 10 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.
To successfully communicate using a privacy code, both the
sending and receiving radios must be tuned to the same channel
withthe same privacy code number (CTCSS or DCS). Each
channel will remember the last privacy code system and number
you select.
