Figure 9: Troubleshooting table for common issues like sound, missing parts, device switching off, device failure to start, neck area too high, and massage feeling too hard.
| Fault | Solutions |
|---|---|
| Sound Issue | Check if the noise is consistent and significantly loud. If it is, it may be normal operation noise from the internal motor. If the noise is abnormally loud or grinding, it might indicate a mechanical issue. In this case, contact customer support for further assistance or a potential replacement. |
| Missing Parts | Check if any parts are still in the packaging. Review the product manual for info on separate parts or accessories. |
| Device switches off suddenly | Device may have been in use for 15mins. Auto-shutoff function activated. Continue using by pressing the 'power' button after resting the unit for 15mins. Over-heat protection function activated. Device is switched off for your safety. Please rest device for 15-30mins before restarting. |
| Device fail to start | Check if device has been used for more than 15mins. If so, let device rest for 15mins before continuing. Device may require longer time to cool in warmer environments. Check if adapter is plugged into socket. Check if adapter output is connected to device power inlet wire. |
| Neck area is too high | Adjust the neck roller positioning up or down by pressing the arrow buttons on the controller. If the neck rollers still can't reach the neck, try placing a seat cushion or a pillow on the sitting part. |
