Intuitive User Interface and White Backlit LCD and Keypad Incorporating Icom’s common Marine Family User Interface designed for simple, intuitive operation. A rotary selector and directional keypad provide quick and easy access to the intended functions. The high contrast white backlit LCD and laser-cut keypad match well with modern boat designs.

Active Noise Cancelling The built-in active noise cancelling provides superb performance.It reduces background noise up to 90% in the received signal and 30% in the transmits 
signal. 

10W Loud Audio, Public Address and Foghorn The IC-M423G has a built-in 10W amplifier that increases the audio output to an external PA speaker. The public address function allows you to make an announcement from the microphone like a loud speaker, the foghorn can also be emitted from the external PA speaker.

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. 

Built-in GPS Receiver The built-in GPS receiver shows your current position, date/time and can be used for DSC calls. The GPS data source is selectable from internal and external GPS.

AIS Target Call with MA-500TR When connected to the optional MA-500TR Class B AIS transponder, the AIS target call function allows you to make an individual DSC call without having to manually input an MMSI number.
