5. Maintenance

5.1 Water Resistance

The CNBRO Smart Ring is 5ATM waterproof, meaning it can withstand water pressure equivalent to a depth of 50 meters. This makes it suitable for swimming and daily wear. However, to ensure its longevity and functionality, it is crucial to avoid exposure to hot water (e.g., hot showers, saunas), deep water diving beyond 50 meters, or any water-related work that involves high-pressure water jets or prolonged submersion at extreme depths.
