code
There are 38 analogue (CTCSS 1 − 38) and 83 digital (CDCSS
39 − 121) codes available per channel. It is only possible to com-
municate using the walkie−talkies when they are each set to the
same channel and CTCSS/CDCSS codes.
The channels and the codes are transmitted as inaudi-
ble signals together with the standard voice commu-
nication. The voice communication is only transferred
to the receiving device’s loudspeaker when the chan-
nel and the code that it is set on is identical to that re-
ceived.
If another subscriber is coincidentally using the same
channel and code, switch to a different, free channel to-
gether with the person operating the device called.
