7. Troubleshooting
If you encounter issues with your Lorell Sit-to-Stand Two-Tier Base, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Desk does not move | Power cable disconnected; Control box error; Overload | Check power connections. Unplug and replug the power for 10 seconds. Reduce weight on desk. |
| Uneven movement | Uneven load; Loose connections | Distribute weight evenly. Check all frame connections and tighten if loose. |
| Error code on display | Specific system fault | Refer to the control box manual (if separate) or contact customer support with the error code. Often, a power cycle (unplug, wait 10s, replug) can resolve temporary errors. |
| Noise during operation | Normal motor sound; Loose components | A slight motor hum is normal. If noise is excessive, check for loose screws or components and tighten. |
