6. Maintenance
6.1. Cleaning
Regularly clean your smartwatch and straps to prevent skin irritation and maintain device performance. Use a soft, lint-free cloth. If necessary, slightly dampen the cloth with water. Avoid harsh chemicals or abrasive materials.
6.2. Water Resistance
The product video and feature bullets indicate an IP68 waterproof level and 1ATM waterproof rating, suggesting resistance to dust and immersion in water up to 1.5 meters for 30 minutes, suitable for daily use. However, the product specifications explicitly state "Water Resistance Level: Not Water Resistant." Due to this contradiction, it is strongly advised to treat the COLMI L28 Smartwatch as NOT WATER RESISTANT to prevent potential damage. Avoid exposing the device to water, including showering, swimming, or heavy rain, until official clarification from the manufacturer is obtained. Water damage is typically not covered under warranty.

Please note the conflicting information regarding water resistance in the product specifications and exercise caution.
