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, 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 then possible when both parties
are using the same channel and CTCSS code. An excep-
tion 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 com-
munication, it may be necessary to switch from CTCSS
code 0" to the CTCSS code being used.
