5. Maintenance
5.1 Cleaning
- After each use, especially in saltwater, rinse the light thoroughly with fresh water to remove salt and debris.
- Wipe the light with a soft, clean cloth. Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the seals or surface finish.
- Ensure the charging port and its cover are free from debris and properly sealed after cleaning.
5.2 Storage
- Store the light in a cool, dry place away from direct sunlight and extreme temperatures.
- For long-term storage, ensure the battery is partially charged (around 50%) to prolong its lifespan. Avoid storing with a completely depleted or fully charged battery for extended periods.
- Keep the light away from sharp objects that could scratch or damage the waterproof seals.
6. Troubleshooting
6.1 Light Not Turning On
- Battery Check: Ensure the battery is charged. Connect the light to a power source using the micro USB cable and allow it to charge for at least 30 minutes.
- Power Button: Confirm that the power button is pressed and held correctly for a few seconds to activate the device.
6.2 Short Battery Life
- Mode Usage: High brightness mode consumes power faster. Using lower brightness settings will extend battery life.
- Full Charge: Ensure the battery is fully charged before each use.
- Battery Degradation: Over time, all rechargeable batteries naturally degrade. If battery life significantly decreases despite proper charging and usage, the battery may be nearing the end of its lifespan.
6.3 Water Leakage
- Immediate Action: If water is suspected to have entered the device, immediately discontinue use and dry the exterior. Do not attempt to charge or operate the light.
- Seal Integrity: Always ensure the charging port cover and any other seals are completely and securely closed before submersion. Even a small gap can compromise waterproofing.
- Contact Support: If leakage occurs, contact customer support. This may indicate a defect or damage to the waterproof seals that requires professional attention.
