The wireless handsets duplicate the radio display and controls on easy-to-read screens viewable under all lighting conditions, even bright sunlight. All primary functions are accessible from the handset with channel scan and favourites, alphanumeric keypad, clear audio, handset station naming and 60-second audio rewind.Designed for Clear CommunicationThis Class D DSC approved radio can make and receive DSC distress signals including your current position, and supports direct calling to other DSC-equipped radios. A dual-channel watch lets you monitor the current channel and emergency channel 16 (in the USA, tri-channel watch monitors the current channel, emergency channel 16, and calling channel 9). A record and replay feature helps to ensure you never miss an important call. The system includes one external speaker with additional outputs for up to four speakers and one optional loudhailer/foghorn.
