To maintain your watch, regularly wipe the screen and strap with a soft, dry cloth. If necessary, use a slightly damp cloth for the strap, then dry thoroughly. Avoid using harsh chemicals or abrasive materials.

To prolong battery life, avoid fully discharging the watch frequently. Charge the watch when the battery level is low. Store the watch in a cool, dry place when not in use for extended periods.
6. Troubleshooting

- Inaccurate health data: Ensure the watch is worn snugly on your wrist, not too tight or too loose. Clean the sensor on the back of the watch. Environmental factors and individual physiology can affect readings.
- Notifications not appearing: Check app permissions on your phone and within the 'Da Fit' app to ensure notifications are enabled for desired applications. Ensure the watch is connected via Bluetooth.
