CTCSS = Continous Tone Coded Squelch System.
All the calls on walkie−talkies which occur within the range of recep-
tion are signalled. 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.

Each CTCSS code complies to a specific audio 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.
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.
Signals are searched for in the eight channels in a continuous
cycle. The icon appears in the display. If an active channel is
detected, the channel search stops. The Ready LED flashes once
per second. Press the P button to enable radio communication.
If the P button is not pressed, channel search resumes after five
seconds.
