Operating the Walkie−Talkies
Selecting the CTCSS
There are 38 analogue (CTCSS 1 − 38) and 83 digital (DCS 1 − 83)
codes available per channel. It is only possible to communicate
using the walkie−talkies when they are each set to the same chan-
nel and CTCSS/DCS code.

/DCS code
The CTCSS/DCS codes are transmitted as inaudible sig-
nals together with the standard voice communication.
When received, the voice communication signal is only
transferred to the loudspeaker when the channel and
CTCSS/DCS code set on the receiver are identical to that
of those received (settings on the transmitter). If, by coinci-
dence, another subscriber is using the same channel and
CTCSS code, change to a free channel together with the
party being called.
An exception here is CTCSS/DCS code 0 (zero). When
this setting is set, all calls made on the channel set can be
heard. In order to participate in the radio communication,
you must set the corresponding CTCSS code.
