Privacy Codes - Retevis RT41 User Manual

Privacy Codes

Your 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 (Digital ly Coded Squelch)provides 83 privacy codes.
This provides a total of 121 Privacy Codes. Either system can be used
on al l 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 0F is not a privacy code, but allows all
signals to be heard on a channel that is set to 0F on both
the CTCSS and DCS systems.
