Maintenance

• Cleaning: Wipe the flashlight body with a clean, soft cloth. For the lens, use a lens cleaning cloth and solution to avoid scratches. Do not use abrasive cleaners or solvents.
• O-Ring Maintenance: The flashlight's waterproof rating relies on its O-rings. Periodically inspect the O-rings for wear or damage. If they appear dry, apply a thin layer of silicone grease. Replace damaged O-rings with the provided spares to maintain waterproof integrity.
• Battery Care: Store the flashlight with a partially charged battery if not used for extended periods. Avoid fully discharging the battery frequently, as this can reduce its lifespan.
• Storage: Store the flashlight in a cool, dry place away from direct sunlight and extreme temperatures.
