When a DSC call is received, the intercom function is in- terrupted with an automatic return to the transceiver mode. The transceiver’s display indicates ‘Receiving DSC calls.’ (p. 41)

When a WX alert is received, “WX ALERT” blinks and a beep sounds. The WX alert sounds after the Intercom use is finished.
