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.
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.
