PMR446 (Private Mobile Radio) walkie−talkies can be used throughout Europe free of

Select DCS /CTCSS
There are 38 analogue (CTCSS 1 − 38) and 83 digital (DCS 1 − 83) squelch 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/DCS code.
The CTCSS/DCS codes are transmitted as inaudible signals together
with the standard voice communication. When received, the voice com-
munication signal is only transferred to the loudspeaker when the channel
and CTCSS/DCS code set on the receiver are identical to that of those re-
ceived (settings on the transmitter). If, by coincidence, another subscriber
is using the same channel and CTCSS/DCS code, change to a free chan-
nel together with the party being called.
