Privacy Codes
Your microTALK® 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 83 privacy codes. This provides a total of 121 Privacy Codes. Either
system can be used on all channels, but both systems cannot be used on the same
channel at the same time.

Mode/Power
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 system (CTCSS or DCS) and privacy
code number. Each channel will
remember the last privacy code system
and number you select.
The privacy code 00 is not a
privacy code, but allows all
signals to be heard on a channel
that is set to 00 on both the
CTCSS and DCS systems.
