Maintenance
1. Water Resistance
The SUNKTA Smart Watch FV26-A is 5ATM waterproof (equivalent to IP68), making it suitable for daily activities such as hand washing, rain, and swimming in shallow water. It is not recommended for hot showers, saunas, or diving, as steam and high water pressure can compromise the seals. Avoid prolonged submersion.
2. Cleaning and Care
Regularly clean your smartwatch and strap to prevent skin irritation and maintain device longevity. Use a soft, damp cloth to wipe the screen and watch body. For silicone straps, mild soap and water can be used. Ensure the watch is completely dry before charging or wearing. Avoid using harsh chemicals or abrasive materials.
Troubleshooting
- Watch Not Turning On: Ensure the watch is fully charged. Connect it to the magnetic charger and check if the charging indicator appears.

- Bluetooth Disconnection: Verify that Bluetooth is enabled on your smartphone and the watch is within range. Restart both the watch and your phone, then attempt to re-pair through the app.
- Inaccurate Health Data: Ensure the watch is worn snugly on your wrist, about one finger's width above the wrist bone. Keep the sensor clean. For sleep tracking, wear the watch throughout the night.
- Notifications Not Appearing: Check app permissions on your smartphone to ensure the companion app has access to notifications. Also, verify that "Do Not Disturb" mode is not active on the watch.
