Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Massager does not turn on. | Power cord not properly connected. Unit overheated. | Ensure power cord is securely plugged into the massager and outlet. Allow the unit to cool down for 30 minutes before attempting to use again. |
| Heat function is not working or is too weak. | Heat function requires a massage mode to be active. Heat is designed to be gentle. | Ensure a massage function (neck or back shiatsu) is active. The heat is intended to be subtle and not as intense as a heating pad. |
| Massage is too intense. | No intensity flap in place. | Ensure the detachable flap is in place over the back massage nodes to reduce intensity. You can also place a towel between your back and the massager. |
| Neck massage nodes are not reaching the correct area. | Neck massage height needs adjustment. | Use the Neck Up/Down arrows on the remote control to adjust the height of the neck massage nodes. |
