Maintenance
1. Water Resistance (IP68)
The LIGE FVA21-D Smart Watch is IP68 waterproof, meaning it is resistant to dust and can withstand immersion in water up to 1.5 meters for 30 minutes. It is suitable for daily use, such as hand washing, rain, and shallow swimming. However, it is not recommended for hot showers, saunas, or diving, as steam and high water pressure may compromise the seal.

3. Battery Care
To prolong battery life:
