code
There are 38 analogue (CTCSS 1 - 38) and 83 digital (CDCSS 39 -
121) codes available per channel. It is only possible to communicate
using the walkie-talkies when they are each set to the same channel
and CTCSS/CDCSS codes.
Note:
1 CTCSS: Continous Tone Coded Squelch System = Selective call
•
2 CDCSS: Continous Digital Coded Squelch System = Selective call
•
Note:
The channels and the codes are transmitted as inaudible signals to-
•
gether with the standard voice communication. The voice communica-
tion is only transferred to the receiving device’s loudspeaker when the
channel and the code that it is set on is identical to that received.
If another subscriber is coincidentally using the same channel and
•
code, switch to a different, free channel together with the person
operating the device called.

Note :
An exception here is code 0 (zero). In the case of this setting,
all the calls on the set channel can be heard regardless of the
CTCSS/CDCSS code. To be able to participate in the radio com-
munication, it may be necessary to set the necessary CTCSS/
CDCSS code.
If you want to communicate with the walkie-talkies which are not
using a CTCSS/CDCSS code, you must select CTCSS/CDCSS
code “0” (zero) on your walkie-talkie.
