Selecting the CTCSS
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.

code
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 necessary to switch
from CTCSS code 0" to the CTCSS code being used.
