Important Note: The watch should not be worn during diving, platform dives, hot showers, saunas, or other activities that involve fast-flowing water. Metal straps are not designed to withstand swims or sweat. To avoid corrosion, please do not wear the watch when swimming in the sea. Water resistance is not permanent and may decrease with daily wear and tear.

Maintenance
To ensure the longevity and optimal performance of your HAYLOU Solar 5 smartwatch, follow these maintenance guidelines:
- Cleaning: Regularly wipe the watch and strap with a soft, dry cloth. Avoid using harsh chemicals, detergents, or abrasive cleaners, as these can damage the watch's finish and seals.
- Water Exposure: While the watch is IP68 waterproof, prolonged exposure to water, especially hot water or high-pressure water, should be avoided. Dry the watch thoroughly after it gets wet.
- Charging: Always use the original charging cable provided with your watch. Ensure the charging contacts on both the watch and the cable are clean and dry before charging to prevent corrosion or damage.
- Storage: When not in use for extended periods, store the watch in a cool, dry place away from direct sunlight and extreme temperatures.
- Strap Care: If you have a silicone strap, clean it with mild soap and water. For metal straps, use a soft cloth. Avoid bending or twisting the straps excessively.
Troubleshooting
Here are solutions to common issues you might encounter with your HAYLOU Solar 5 smartwatch:
