5. Maintenance and Care
5.1 Cleaning
To keep your Smart Ring in optimal condition and ensure accurate readings, regular cleaning is recommended:
- Wipe the ring with a soft, damp cloth.
- Avoid using harsh chemicals, abrasive cleaners, or solvents, as these can damage the ring's finish and sensors.
- Ensure the charging contacts are clean and dry before charging.
5.2 Water Resistance
The Smart Ring has an IP68 waterproof rating, meaning it is resistant to dust and can withstand submersion in water up to 1.5 meters for 30 minutes. This makes it suitable for daily activities such as:
- Washing hands
- Showering
- Swimming in shallow water
However, it is not recommended for diving, high-pressure water activities, or prolonged submersion in hot water (e.g., hot tubs, saunas) as steam and high temperatures can compromise the seal over time.

The Smart Ring is IP68 waterproof and sweatproof, protecting it from daily exposure to water.
