9. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Scale does not turn on. | Batteries are dead or incorrectly installed. | Check battery polarity or replace with new batteries. |
| Inaccurate weight readings. | Scale is on an uneven surface; scale needs calibration; user is wearing shoes/socks. | Place scale on a hard, flat surface. Step on and off quickly to calibrate. Ensure bare feet for BIA. |
| Body composition data not displayed or transferred to app. | Feet are not making proper contact with electrodes; Bluetooth is off; app is not open or paired. | Ensure bare feet are on all four electrodes. Turn on Bluetooth on your device. Open the app and ensure it's paired. |
| User not recognized. | User profile not set up in app; significant weight change. | Create or update user profile in the app. Step on the scale to re-establish recognition. |
