In this operating mode the audio is enabled only when you receive
a radio signal with an appropriate CTCSS/DCS tone/code, as pro-
grammed by the radio link provider.
If the CTCSS/DCS code/tone of the signal is correct, the status LED
turns permanently orange and stays on for the whole length of the
signal.If the received signal does not contain the correct code/tone,
the audio remains disabled and the status LED turns green.

Depending on the programming, you may temporarily disable the
CTCSS/DCS tone/code in reception mode to monitor the radio
traffic (Monitoring feature). For more detailed information, see
paragraph 6.6.
7.2 Transmission
7.2.a Transmission of CTCSS/DCS tones/codes
If the transceiver has been programmed to transmit a CTCSS tone
or DCS tone, no specific action is required. The CTCSS tone or DCS
code is sent automatically every time a transmission is started (with-
out any signal).

8. Channel scan
The scanning feature enables to automatically search for pro-
grammed channels and is particularly useful if several channels have
been programmed. The feature enables to monitor radio traffic and
to reply to calls on different channels, which are "explored" cyclically
in sequence.
When the radio receives a valid signal during scanning it stops and
outputs the communication through the speaker. The channel scan is
automatically resumed as soon as the signal ceases.
If the radio has been programmed to receive CTCSS/DCS tones/
codes (see paragraph 8.1), it is possible to configure the radio so that
it stops only when the received signals contain a specific tone/code.
For additional information, contact the radio link provider.
