All function control including DSC operation, can be made from the CommandMic™, HM-195B, and the RF unit, IC-M400BBE, can be installed in an out-of-sight place. The new menu system is shared with Icom’s latest models. The bottom line of the dot-matrix display shows the software key functions which can be toggled with the left and right buttons. 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. The IC-M400BBE has a built-in 10 W amplifier that increases the audio output from an 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 external speaker.

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.
