Product Overview

A compact choice for boats that need a radio but don’t have room at the helm station. 

The M400BB includes a black box main body and a CommandMic IV™ remote control microphone. The two-component radio can easily be installed behind a wall or console, leaving a small or hidden footprint, and completely controlled from a remote position.

Although compact in size, the M400BB possesses the same robust functionality found in the M424 fixed mount. Features include Class D DSC and the CommandMic IV™ intuitive soft-key interface design. Active noise canceling, a 10W loudspeaker and Public Address are built in for optimal audio performance.

Key Features

  • Space-Saving, Two-Piece Configuration: The IC-M400BB consists of a two-piece, black box configuration. All function control including DSC operation, can be made from the CommandMic™, HM-195B/SW, and the RF unit, IC-M400BB, can be installed in an out-of-sight place.
  • New Intuitive User Interface: 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.
  • Active Noise Canceling: The built-in bidirectional active noise canceling 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-M400BB has a built-in 10W 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.
  • 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 COMMANDMIC display. When receiving DSC information from another vessel, the radio 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 set up an individual DSC call from the MA-500TR.
