Fixed Marine VHF Black Box 156-163MHz 25W, with Class D DSC

A black box VHF is a modular system where the main unit of the radio is installed out of sight, for example in a console or locker. Full control of the VHF is done via a remote microphone (CommandMic), which saves valuable dashboard space.

No, the IC-M400BBE VHF is now a discontinued product by the manufacturer. It is advantageously replaced by the new generation models IC-M410BB and IC-M510BB. However, it remains an excellent opportunity at a reduced price for standard replacement of an existing installation.

The central unit is very compact. It measures approximately 216 mm in width, 79 mm in height, and 125 mm in depth, which greatly facilitates its integration into tight spaces on your boat.

Yes, the central unit of this VHF benefits from the IPX7 waterproof standard. This means it is designed to withstand temporary immersion in water (up to 1 meter deep for 30 minutes).

This fixed VHF offers switchable transmission power. You can transmit at 25 Watts for long-distance communications, or reduce the power to 1 Watt for local communications, which saves onboard energy.

Class D DSC (Digital Selective Calling) is an essential safety feature at sea. The radio integrates an independent receiver dedicated exclusively to channel 70. This ensures permanent and automatic monitoring of distress calls, even when you are using another channel for regular voice communications.

Yes, it has a built-in audio amplifier delivering over 10 W of power. By connecting a compatible external loudspeaker (PA - Public Address function), you can use it as a foghorn or a sound system on deck.

The central unit is installed invisibly in a console, locker, or behind a bulkhead using its mounting bracket. Only the remote microphone and its connection port need to be installed accessibly on the dashboard or at the chart table.

The VHF requires a 13.8 V nominal DC power supply (accepted range of 12.0 to 13.8 V DC) with the negative grounded. It consumes a maximum of 5.5 A during transmission at full power (25 W).

Yes, it is entirely possible to connect an external loudspeaker. The device provides an audio output power of more than 10 W (into 4 Ω) via the blue (+) and black (-) wires, ensuring excellent audibility even in a noisy environment.

Connection to the NMEA 0183 network is made via the dedicated wires of the harness: the yellow wire corresponds to the GPS input (Data-H) and the green wire to the GPS input (Data-L). This allows the VHF to receive the position data necessary for the proper functioning of the DSC.

You will need a standard marine VHF antenna with a nominal impedance of 50 Ω. The antenna is not supplied with the device and must be installed as high as possible and clear of any obstacles to optimize the range of your communications.

This black box is designed to be controlled exclusively by a remote CommandMic microphone from the HM-195 series (such as models HM-195B or HM-195SW). Please note, depending on the package, this microphone may be sold separately.

Yes, when correctly connected to a compatible chartplotter or navigation equipment via NMEA 0183, it can receive and transmit the position data of other vessels obtained during DSC calls to the screen.

As this model is nearing the end of its commercial life, ICOM now offers the new generation black box VHF radios IC-M410BB and IC-M510BB. These new models integrate modern features such as NMEA 2000 compatibility and the ability to connect multiple handsets simultaneously.

Yes, to use a fixed marine VHF radio with the DSC (Digital Selective Calling) function at sea, it is mandatory to possess at least the Restricted Radiotelephone Operator's Certificate (CRR) or a valid pleasure craft operator's card, depending on your navigation area and current regulations.
