Built-in GPS Receiver (IC-M323G only) The built-in GPS receiver shows your current position and time and can be used for DSC calls. GPS data source is selectable from internal and external GPS (and GPS-OFF setting).

Intuitive User Interface Icom’s common Marine Family User Interface provides simple operation for the boat owner. A rotary selector and directional keypad provide intuitive operation. The high-definition dot-matrix display allows all information to be clearly viewed. 

Built-in Class D DSC The built-in DSC watch function monitors Ch. 70 (DSC channel) activity, even while you are receiving another channel. DSC functions include: distress, individual, group, all ships, urgency, safety, position request/report, polling request and DSC test calls. 

IPX7 Waterproof Protection The IC-M323/G withstands submersion in up to 1.0m depth of water for 30 minutes. It is equivalent to the IPX7 standard. 

Common NMEA Interface When receiving DSC information from another vessel, the IC-M323/G can transfer it to a navigational device via NMEA 0183 connectivity.

Compatible with MA-500TR Class B AIS Transponder The IC-M323/G can be integrated with the MA-500TR Class B AIS Transponder, which allows you to transmit DSC individual calls to a selected vessel instantly without manual MMSI entry. It is very handy if you are waiting to contact vessels on the AIS screen - an essential safety feature in an emergency.

Favorite Channel Function  This function promotes quick channel selection. Set the “Tag” channel to the channels used most often. When pushing the up/down buttons on the hand microphone, only the tagged channels 
are selected, while untagged channels are skipped
