IC-M800 250W

The Icom Marine IC-M800 250W is a marine MF/HF radio installation. It is normally installed at the bridge radio console with external antenna, tuner and earthing/counterpoise system. It is designed for long-range voice and distress/safety communication beyond normal VHF range. The operating principle relies on MF/HF radio transmission and reception, with DSC where fitted/approved. The supplied entry gives no additional verified capacity, pressure, power or dimensional figure for this model. Compared with neighbouring models, the relevant differences are transmitter output, antenna tuner, control unit and GMDSS interfaces; these must be confirmed from the installed documentation rather than inferred from the model designation alone. Service and survey attention should concentrate on transmit/receive checks, tuner/antenna/grounding, cooling, identity/position inputs and power. For exact ratings, dimensions, tolerances, test limits and model-specific settings, refer to the manufacturer documentation for the exact figure.

●Position/identity or data-interface failure caused by wiring or configuration faults, noticed as missing or incorrect safety data
●Power-source failure caused by breaker, fuse, converter or emergency-supply faults, noticed as dead equipment or loss of required GMDSS availability

Service & Maintenance

Carry out the permitted operational/self-tests, inspect antennas, feeders, connectors, controls and cooling, and verify normal and emergency power where required. Check vessel identity, position and interfaces appropriate to the equipment type and review recurring alarms or logbook entries. A radio surveyor should confirm the installation and programmed data against the approved radio documentation.
