CTCSS PRIVACY CHANNELS
Continuous Tone-Coded Squelch System or
CTCSS is used to reduce the annoyance of
listening to other users on a shared two-way radio
communications channel. It is sometimes referred
to as privacy channels or sub-channels since it
has the effect of creating multiple virtual channels
which are all using the same radio frequency. It
does not encrypt the transmission, rather it mutes
other transmissions on the same CB channel that
are not transmitting using a CTCSS virtual channel.
To activate:
1. Press the MENU button twice. The current
CTCSS code will flash on the display.
2. Press the UP

button to change the

3. Press the PTT button to confirm and return to

4. Individual channels can be assigned different
CTCSS codes.
5. Always ensure the CB’s are set to the same
CTCSS code (or set to OFF – shown as “OF” on
the LCD display) otherwise you will not hear the
transmissions from the other CB’s.
