5. Maintenance

5.1 Cleaning

To maintain the performance and appearance of your smart ring:

• Wipe the ring regularly with a soft, dry, lint-free cloth.
• For stubborn dirt, slightly dampen the cloth with water. Avoid harsh chemicals or abrasive materials.
• Ensure the sensors on the inside of the ring are clean for accurate readings.

5.2 Water Resistance

The Amwentu Smart Ring is waterproof with a depth rating of up to 100 meters (10 ATM). This means it is suitable for:
