Electromagnetic Radar equipment is represented by the SF-71LF / C1 model from Hyundai Welding Co., Ltd. (Pohang), which supports both X-Band and S-Band frequencies and complies with IMO SOLAS regulations. This radar system, approved by DNV, includes a magnetron that typically lasts between 5,000 to 8,000 operational hours, after which it should be replaced. Regular maintenance tasks include annual lubrication of the antenna bearing and weekly performance monitoring tests as per IMO requirements. The company advises keeping a spare magnetron on hand for such models due to potential end-of-life issues within this period, with a lead time of 1-3 weeks for replacements. Annual inspections are also recommended to ensure optimal operation. Common failures include antenna rotation motor wear after over 30,000 hours, display backlight failure, heading marker drift, and waveguide moisture ingress due to compromised sealing.
