Scan
The channel scan starts or is interrupted with the Scan key. The scanning will
be done on the channels enabled for it, it will stop when a signal is found and will
automatically resume after 4 seconds if the channel is clear again. By default
only the first 8 channels are scanned; to remove a channel from this list, select
the desired channel and then keep pressed the Scan key for 2 seconds.
The icon will disappear from the display. To add again the channel to the
scan list, hold down the Scan key for 2 seconds; the display will show again
the icon.
