When using the searchlight in high-humidity environments, fogging may occur. This does not affect its optical performance during use. After use, place the searchlight in a dry, ventilated area for a short period to allow the fog to dissipate naturally. At night, the searchlight may trigger false obstacle avoidance. Depending on the situation, disable obstacle avoidance and operate the aircraft and searchlight in relatively open, unobstructed areas. Do not directly touch the searchlight lens or scratch its surface coating with hard objects, as this will reduce light output efficiency and affect luminous flux and illuminance. When cleaning the lens, use only a soft, dry cloth. Never use alkaline cleaners. Store the searchlight in a safe case in a dry, ventilated environment with an ambient humidity of 40–50%.
