Černá skříňka pevné námořní VHF 156–163 MHz 25 W s ASN třídy D

A black box VHF 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 achieved via a remote microphone (CommandMic), which saves valuable dashboard space.

No, the IC-M400BBE VHF is now a discontinued product from the manufacturer. It is advantageously replaced by the new-generation IC-M410BB and IC-M510BB models. 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, making it easy to integrate into the tight spaces on your boat.

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

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

The ASN (Digital Selective Calling) Class D is a critical safety function at sea. The radio includes an independent receiver dedicated exclusively to channel 70. This ensures continuous and automatic monitoring of distress calls, even when using another channel for standard voice communications.

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

VHF radios require a nominal 13.8 V DC power supply (acceptable range: 12.0 to 13.8 V DC) with negative grounded. Maximum current draw is 5.5 A during full-power transmission (25 W).

Yes, it is entirely possible to connect an external speaker. The device provides an audio output power of over 10 W (at 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 in the loom: 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 position data required for proper AIS-SART operation.

You 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 microphone from the HM-195 series (such as the HM-195B or HM-195SW models). Note that 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 nearing the end of its commercial life, ICOM now offers the next-generation black box VHFs: IC-M410BB and IC-M510BB. 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 radio with Digital Selective Calling (DSC) at sea, you must hold at least the Short Range Certificate (SRC) or a valid recreational boating license, depending on your cruising area and applicable regulations.
