Black Box Transceiver – Icom Quality. Small Footprint.


Icom’s M400BB is perfect for boats that need a radio but don’t have room on the helm. The M400BB consist of a two-piece, black box configuration.

The HM-195 also utilizes the same user soft key interface used on Icom’s latest range of marine radios for easy operation.

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 Amplifier

The 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.

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.
