Digital Selective Calling Features

DSC uses a unique ID (MMSI code) similar to a telephone number, allowing you to make  contact with a specific boater or group of boaters in your area. A total of 100 address IDs can be stored with a 5-character name.

Position Request and PositionReport with External GPS Receiver

With an external GPS receiver, the position request and position report functions allow you to exchange ships position. The received position information can be plotted on a third party GPS or other navigation equipment which accepts NMEA data format. The polling (request/reply) function checks whether a specific ship is in the communication range.

New public address (PA) and RX speaker functions

Use the hand microphone as part of a public address system and make an announcement on-board or to shore through an external loud speaker or hailer. The RX speaker function allows you to monitor the received audio from the loud speaker or hailer while you are on the deck or tower.

New optional COMMANDMICII™

The new optional COMMANDMICII™ makes it convenient for using the IC-M422 from a separate cabin or tower. It allows you to control most functions* of the IC-M422, including remote power ON/OFF, PA and RX speaker functions. (*except DSC operation)

Force 5 Audio
