3.3 Cleaning and Care

4. Troubleshooting
4.1 Device Not Powering On
- Ensure the device is fully charged. Connect it to the charger and wait a few minutes before attempting to power it on again.
- Check the charging cable and power source for proper connection and functionality.
4.2 Inaccurate Activity Tracking
- Verify that your personal information (height, weight, stride length) is accurately entered in the device settings. Incorrect data can lead to inaccurate step and distance calculations.
- Ensure the tracker is worn snugly on your wrist, typically about one finger's width above your wrist bone. Loose fit can affect sensor accuracy.
- Note that step counting relies on arm movement. Activities that do not involve typical arm swings (e.g., pushing a shopping cart) may result in undercounting.
4.3 Screen Unresponsive or Frozen
- Attempt a soft reset by pressing and holding the side button (if applicable) for approximately 10-15 seconds until the device restarts.
- Ensure the screen is clean and dry.
4.4 Charging Issues
- Check that the magnetic charging pins are clean and free of debris.
- Ensure the charging cable is not damaged and is securely connected to both the device and the power source.
- Try a different USB power adapter or USB port.
