- Storage: Store the scale in a dry, cool place away from direct sunlight and extreme temperatures.
- Battery Care: If using rechargeable batteries, ensure they are charged regularly to maintain optimal performance. If the scale will not be used for an extended period, fully charge the batteries before storage.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No display/Scale won't turn on | No power, discharged batteries, faulty AC adapter. | Check AC adapter connection. Charge batteries. Replace AC adapter if necessary. |
| Inaccurate weight readings | Scale not on a level surface, object touching scale, scale needs calibration. | Ensure scale is on a flat, stable surface. Remove any objects touching the scale. Perform calibration if needed. |
| Display shows "Err" | Overload, internal error. | Ensure weight does not exceed 660 lbs. Turn off and restart the scale. If error persists, contact support. |
