code
There are 38 codes available per channel. It is only possible to
communicate using the walkie−talkies when they are each set to
the same channel and CTCSS code.
The channel and CTCSS code are transmitted as inau-
dible signals together with the standard voice commu-
nication. When received, the voice communication sig-
nal is only transferred to the loudspeaker when the
channel and CTCSS code set on the receiver are iden-
tical to that of those received. If, by coincidence,
another subscriber is using the same channel and
CTCSS code, change to another free channel together
with the party being called.
