Jūrinė VHF juodoji dėžė 156-163 MHz 25W, su ASN D klasės

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

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 budget opportunity for standard replacement of an existing installation.

The central housing is very compact. It measures approximately 216 mm in width, 79 mm in height, and 125 mm in depth, making it easy to integrate into the tight spaces on your boat.

Yes, the main unit of this VHF meets the IPX7 waterproofing standard. This means it is designed to withstand temporary immersion in water (up to 1 meter depth for 30 minutes).

This fixed VHF offers switchable transmit power. You can transmit at 25 Watts for long-range communications, or reduce power to 1 Watt for local communications, saving onboard energy.

ASN (Digital Selective Calling) Class D is an essential safety function at sea. The radio includes 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 standard voice communications.

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

The main unit is installed invisibly in a console, cabinet, or behind a bulkhead using its mounting bracket. Only the remote microphone and its connection plug must be installed in an accessible location on the dashboard or at the chart table.

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

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

The connection to the NMEA 0183 network is made via the dedicated wires in 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 required for the correct operation of ASN.

You need a standard marine VHF antenna with a nominal impedance of 50 Ω. The antenna is not supplied with the unit 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 CommandMic remote microphone from the HM-195 series (such as the HM-195B or HM-195SW models). Note: depending on the package, this microphone may be sold separately.

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

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

Yes, to use a fixed marine VHF with DSC (Digital Selective Calling) at sea, you must hold at least the SRC (Short Range Certificate) or a valid recreational craft driving licence, depending on your cruising area and current regulations.
