Active Noise Cancelling
The built-in bidirectional active noise cancelling reduces background noise to up to 90% and improves both your transmitted voice and incoming call. Hear and be heard more clearly.
10W Loud Audio, Public Address and Foghorn
The IC-M423 has a built-in 10W amplifier that increases the audio output from additional external speaker. The public address function allows you to make an announcement from the microphone like a loud speaker, and the foghorn can also be emitted from the additional external 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.
Common NMEA Interface
When connected to an external GPS receiver, current position and time are shown on the IC-M423's display. When receiving position information from another vessel, the IC-M423 can transfer it to a navigational device via NMEA 0183 connectivity.
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 a MMSI number.
