In Digital Mode, if a received signal contains a DG-ID different from the DG-ID setting of this
transceiver, the upper green and lower blue lights flash. In FM mode, the upper and lower green
lights flash when receiving a signal containing a tone or DCS different from the squelch setting of
this station.

switch is pressed when a frequency other than the amateur ham radio band is
selected, an alarm tone (beep) will be emitted, “
