Radar equipment falls under essential navigation technology. The SM-70 / C1 model from Hyundai Welding Co., Ltd. (Pohang) is certified for X-Band and S-Band frequencies, meeting IMO SOLAS requirements. This electromagnetic radar, approved by DNV, is designed to ensure safe maritime operations. Common issues include magnetron failure after 5,000-8,000 hours of operation, antenna bearing wear after 30,000+ hours, display backlight malfunction, heading marker drift, and water ingress in the waveguide due to pressure disturbances. For maintenance, replace the magnetron every 5,000-8,000 hours, lubricate the antenna bearing annually, perform a weekly performance test, and conduct an annual inspection. Keep a spare magnetron on board for model versions equipped with one; replacement typically takes 1-3 weeks.
