VHF Radio · GMDSS
The Zenitel AlphaCom Marine-C is a marine VHF radiotelephone. It is normally installed at the bridge radio console with its antenna high on the vessel. It is designed for ship-to-ship, ship-to-shore, port and safety voice communication. The operating principle relies on radio-frequency voice transmission and reception in the VHF marine band. The supplied entry gives no additional verified capacity, pressure, power or dimensional figure for this model. Compared with neighbouring models, the relevant differences are control layout, remote stations, approval configuration and antenna arrangement; 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 performance, audio, antenna/feeder condition and normal/emergency power. For exact ratings, dimensions, tolerances, test limits and model-specific settings, refer to the manufacturer documentation for the exact figure.
Every value below comes from the manufacturer datasheet or class-society record on file for this model.

What our service work and the manufacturer documentation say about keeping this model running.
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.
Carry fuses, approved handsets/microphones or control accessories where applicable, antenna connectors and feeder repair items, selected power-supply components and manufacturer-recommended interface/control spares. The spare scale should match the vessel's declared GMDSS maintenance method.
