Mounting the Light

Maintenance

- Cleaning: Regularly wipe the flashlight body with a soft, damp cloth. Keep the lens clean and free of dirt or debris. Do not use abrasive cleaners.
- Battery Care: Recharge the battery using the provided charger when the light output diminishes. Store the battery in a cool, dry place when not in use for extended periods.
