6. Maintenance
To ensure the longevity and optimal performance of your F1200 headlight, follow these maintenance guidelines:
- Cleaning: Wipe the light and mount with a soft, damp cloth. Avoid using harsh chemicals or abrasive materials.
- Storage: Store the light in a cool, dry place when not in use. If storing for extended periods, ensure the battery is partially charged (around 50%) and recharge every few months to prevent deep discharge.
- Water Resistance: The F1200 is IP67 waterproof. While it can withstand immersion up to 1 meter for 30 minutes, it is not designed for prolonged underwater use. Ensure the USB port cover is securely closed to maintain water resistance.
