What our service work and the manufacturer documentation say about keeping this model running.
Perform operational and self-tests permitted by the vessel's procedures without generating unintended distress alerts. Inspect antennas, feeders, grounding, power supplies, backup batteries and connected navigation-data inputs. Verify programmed station identity, position input, time and configured communication services against approved records. Check handsets, microphones, printers and alarm interfaces where fitted. Maintain software, licenses and service subscriptions required by the installed system. Refer to manufacturer and regulatory documentation for exact test methods, battery criteria and approved servicing.
Keep fuses, handset or microphone accessories, printer consumables where applicable, selected power-supply components and manufacturer-recommended electronic spares. Antenna or feeder repair materials and backup-battery arrangements should reflect the vessel's redundancy plan. Preserve type approval and programmed identity when replacing core units.
