3. Setup
3.1 Initial Battery Preparation
Before first use, the battery compartment (end cap) must be unscrewed to access the battery. Remove the negative contact insulator disc located between the battery and the contact point. This insulator prevents accidental discharge during shipping. Re-screw the end cap firmly to ensure proper contact and water resistance.

5. Maintenance
- Rinse After Use: After each dive, thoroughly rinse the dive light with fresh water to remove salt, sand, and other debris.
- Dry Thoroughly: Ensure the light is completely dry before storing or charging.
- Inspect O-rings: Regularly inspect the O-rings for any signs of damage, cracks, or dirt. Clean them gently if necessary.
- Lubricate O-rings: Apply a thin layer of silicone grease to the O-rings periodically to maintain their sealing properties.
- Battery Storage: For very long-term storage (several months or more), it is recommended to remove the battery from the light. Store the battery in a cool, dry place.
- Clean Contacts: Keep the battery contacts and the light's internal contacts clean and free of corrosion.
6. Troubleshooting
- Light Does Not Turn On:
- Ensure the battery is properly inserted and fully charged.
- Verify that the negative contact insulator has been removed from the battery compartment.
- Check if the light is in safety lock mode. Double-click the button to unlock.
- Reduced Brightness or Short Runtime:
- The battery may need recharging.
- Ensure the light is not overheating. The DL08 has thermal regulation that may reduce output to prevent damage.
- Water Leakage:
- Immediately remove the battery and dry the light.
- Inspect O-rings for damage, dirt, or improper seating. Replace if necessary.
- Ensure the end cap is screwed on tightly and correctly aligned.
