Selecting the CTCSS code

CTCSS: Continous Tone Coded Squelch System
All the calls on walkie-talkies which occur within the range of
reception are signalled. A condition for this is that all the walkie-
talkies are set to the same channel. To prevent mutual interfer-
ence, a CTCSS code can be defined for the set channel. 38
CTCSS codes can be set per channel.

Each CTCSS code complies to a specific tone frequency
transmitted by the walkie-talkie. Communication between
the subscribers is only then possible when both parties
are using the same channel and CTCSS code. An exception
is CTCSS code "0". In the case of this setting, all the calls on the
set channel can be heard regardless of the CTCSS code. To be
able to participate in the radio communication, it may be neces-
sary to switch from CTCSS code "0" to the CTCSS code being
used.
If you want to communicate with the walkie-talkies which are not
using a CTCSS, you must select CTCSS code "0" on your
walkie-talkie.
