/ CDCSS
The CTCSS codes are transmitted as inaudible signals
together with the standard voice communication. When
received, the voice communication signal is only trans-
ferred to the loudspeaker when the channel and CTCSS
code set on the receiver are identical to the data received
(settings on transmitter). If, by coincidence, another sub-
scriber is using the same channel and CTCSS code,
change to a free channel together with the party being
called.
