7. Maintenance
7.1 Cleaning
- Wipe the flashlight body with a soft, damp cloth. Avoid abrasive cleaners.
- Clean the lens gently with a lens cloth to remove dust or smudges.
- Periodically clean the threads and O-rings. Apply a thin layer of silicone grease to the O-rings to maintain water resistance.
7.2 Storage
- Store the flashlight in a cool, dry place away from direct sunlight.
- For long-term storage, remove the battery to prevent potential leakage or discharge.
8. Troubleshooting
- Flashlight does not turn on:
- Check if the battery is installed correctly with the positive (+) end facing the head.
- Ensure the battery is charged.
- Tighten the tail cap completely. A loose tail cap can prevent electrical contact.
- Light is dim or flickers:
- The battery may be low. Recharge the battery.
- Clean the battery contacts in the flashlight and on the battery itself.
- Water ingress:
- Ensure all parts, especially the tail cap, were securely tightened before exposure to water.
- Check O-rings for damage or improper seating. Replace if necessary.
- Flashlight dropped and stopped working:
- While durable, the flashlight is not entirely shock-proof. Internal components can be damaged by severe impacts. Contact support if the issue persists after checking battery and connections.
