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.
