Privacy Codes
•
Your microTALK ® radio incorporates two (2) 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 104 privacy
codes. This provides a total of 142 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.
