Manutenzione

1. O-Ring Care

The SD11 features a dual O-ring sealing system for superior waterproofing. To ensure longevity and prevent leaks:

• Regularly inspect O-rings for cuts, cracks, or deformation.
• Clean O-rings and their grooves after each dive to remove salt, sand, or debris.
• Apply a thin layer of silicone grease to the O-rings periodically to keep them supple and maintain a good seal.
• Store the flashlight with the O-rings slightly loosened if not used for extended periods.

2. Pulizia

After each use, especially in saltwater, rinse the flashlight thoroughly with fresh water. Wipe it dry with a soft cloth. Do not use harsh chemicals or abrasive materials.

3. Conservazione

Store the dive light in a cool, dry place away from direct sunlight and extreme temperatures. If storing for an extended period, ensure the battery is partially charged (around 50%) and recharge every few months to prolong battery life.

The professional waterproof construction with dual O-rings and AL6061-T6 aluminum body ensures durability and corrosion resistance.
