Wipe the headlamp body with a soft, damp cloth. Do not use abrasive cleaners or solvents. Ensure the charging port cover is securely closed after charging to maintain its waterproof integrity.
2. Storage
Store the headlamp in a cool, dry place away from direct sunlight and extreme temperatures. If storing for extended periods, ensure the batteries are fully charged and recharge them periodically to prolong battery life.
3. Waterproofing
The headlamp is IPX7 waterproof, meaning it can withstand immersion in water up to 1 meter for 30 minutes. However, ensure all ports and battery compartments are sealed properly before exposure to water.
