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.

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.
