Inspection

Inspector Detail

Common issues

  • Magnetron/transceiver output power degradation over time, reducing detection range
  • Antenna motor or rotation bearing wear causing scan speed irregularity or noise
  • Waveguide or radome moisture ingress causing performance loss or arcing
  • Display unit dimming or intermittent faults with unit age
  • Radar-to-radar or radar-to-VHF/AIS interference
  • Loose or corroded antenna unit cabling/connectors at the mast

Inspection checklist

  • Performance monitor / power output check where fitted
  • Visual inspection of antenna unit, radome and waveguide connections for corrosion or water ingress
  • Check azimuth/bearing accuracy against a known reference target or gyro input
  • Confirm ARPA/target tracking and alarm functions operate correctly
  • Check interswitch and network integration with ECDIS/bridge systems where fitted
  • Inspect antenna motor gearbox and bearings for wear or noise
  • Verify heading and position sensor inputs are correctly aligned
  • Check display for image quality, range ring accuracy and tuning

Service intervals

Antenna unit inspection (bearing, motor, waveguide seals)annually
Performance monitor checkannually, or per flag/class requirement for radar equipment
Radome/enclosure seal and gasket checkannually
IMO radar performance test (SOLAS compliance)at each annual survey

Typical wear limits

Transmitter output powertrend the performance monitor reading against the commissioning baseline - a significant drop indicates magnetron/transceiver degradation; confirm the acceptable threshold in the Furuno technical manual rather than assuming a fixed figure

Ranges are typical for this design class. Always confirm against the manufacturer documentation for your serial number.

Critical spares

  • Magnetron (transceiver output tube) - order via the Furuno service network using the reference in the unit's own documentation
  • Antenna motor/drive assembly
  • Display unit power supply module and fuses
  • Waveguide gaskets/seals
  • Antenna unit cabling and connectors

Safety

  • Microwave radiation exposure near the scanner - do not stand in front of the antenna while transmitting
  • High voltage present inside transceiver/display units - only qualified radio/radar technicians should open these
  • Rotating antenna hazard - lock out rotation before working near the scanner unit

Class survey

Radar is SOLAS-mandated navigation equipment. Surveys check valid performance test records, correct configuration for vessel type/tonnage, and integration with other bridge navigation equipment; surveyors typically request evidence of the annual radar performance check rather than performing a full technical test themselves.

Estimated lifetime: magnetron life is commonly quoted by manufacturers in the low thousands of transmit hours (industry range often cited around 2,000-5,000 hours for this class of unit) - treat as a planning indicator only, confirm against Furuno's own documentation for the FAR-2228

Makers and authorised dealers rarely quote marine equipment without the vessel. With these details we can check availability and prices faster; without them we may have to ask first, which can cost a few days. If you cannot share the vessel, a photo of the equipment’s rating plate does the same job — attach it below or send it as a reply to our confirmation e-mail.
