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 interference, a CTCSS code can be
defined for the set channel. 38 CTCSS codes can be set per channel.
Note
: CTCSS- and DCS-codes can only be used alternatively.

☞
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 “00” (= OF / off). 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 “00” 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 “00” on your walkie-talkie.
