code
There are 38 analogue (CTCSS 1 − 38) and 83 digital (DCS 1 − 83) 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/DCS code.
The CTCSS/DCS codes are transmitted as inaudible signals together with
the standard voice communication. When received, the voice communica-
tion signal is only transferred to the loudspeaker when the channel and
CTCSS/DCS code set on the receiver are identical to that of those re-
ceived (settings on the transmitter). If, by coincidence, another subscriber
is using the same channel and CTCSS/DCS code, change to a free chan-
nel together with the party being called.

An exception here is CTCSS/DCS code 0 (zero). When this setting is set,
all calls made on the channel set can be heard. In order to participate in
the radio communication, you must set the corresponding CTCSS/DCS
code.
