7 USING THE RADIO WITH CTCSS/DCS TONES/CODES
7.1 Reception
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.

The scanning feature enables to automatically search for pro-
grammed channels and is particularly useful if several channels have
beenprogrammed.Thefeatureenablestomonitorradiotrafcand

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.
