General Warnings and Instructions
- Do not disassemble the diving light.
- Before opening or closing the light, always check the O-rings for dirt, sand, hair, or dust. Use a soft cloth to clean the O-rings if necessary. Inspect O-rings for cracks or blemishes. Apply a thin, even coat of silicone grease to the O-rings regularly to maintain their condition and ensure a proper seal. If cracks or blemishes are found, replace the O-rings immediately.
- Do not open the light while it is submerged in water.
- After each use, wash the exterior of the light thoroughly with clean, fresh water. Soaking the light in fresh water helps remove salt deposits before storage.
- Do not disassemble, modify, remanufacture, puncture, or damage the device or its battery.

- Dispose of the light and batteries according to local waste disposal regulations and laws. Contact your local waste disposal department for guidance.
- If using an external battery charger, ensure it is a WEEFINE accessory approved for this product.
- Only replace the battery with a WEEFINE-approved replacement battery. Using an incorrect battery may pose a risk of fire or explosion.
