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 channels (CH1-CH22), but
both systems cannot be used on the same channel at the same time.
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.
