Operating the Walkie−Talkies
Selecting the CTCSS code
All the calls on walkie−talkies are signalled which occur within the
range of reception. A condition for this is that all the walkie−talkies
are set to the same channel. To prevent mutual interference, a
CTCSS code can be defined for the set channel. 38 CTCSS codes
can be set per channel.

If you want to communicate with the walkie−talkies which are not
using a CTCSS code, you must select CTCSS code 0" on your
walkie−talkie.

Each CTCSS code complies to a specific tone frequency
transmitted by the walkie−talkie. Communication between
the subscribers is only possible when both parties are us-
ing 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 necessary to switch from CTCSS code 0" set to
the CTCSS code being used by the subscriber found.
