The CTCSS codes are transmitted as inaudible signals to-
gether with the standard voice communication. When re-
ceived, the voice communication signal is only transferred to
the loudspeaker when the channel and CTCSS code set on the
receiver are identical to that of those received. 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 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 cor-
responding CTCSS code.
Monitor function
The Monitor function enables the search for weak signals on the chan-
nel currently set. If you receive an external signal, switch to a free chan-

prevent interference.
