Electromagnetic Radar equipment is represented by the SW-309L Cored / M21 model from Hyundai Welding Co., Ltd. (Pohang). This radar system supports X-Band and S-Band frequencies, meeting International Maritime Organization (IMO) SOLAS requirements. The device requires regular maintenance to ensure optimal performance; a magnetron replacement is needed every 5,000 to 8,000 hours, and the antenna bearing should be lubricated annually. Additionally, weekly tests are necessary to comply with IMO regulations. Common failures include magnetron end-of-life after approximately 5,000 to 8,000 operating hours (for magnetron models), antenna-rotations motor wear after over 30,000 hours, display backlight failure, heading marker drift, and water ingress in the waveguide due to pressure issues. Spare parts for the magnetron should be kept on board; replacements are typically available within 1-3 weeks from Hyundai Welding Co., Ltd. (Pohang).
