Troubleshooting

If an issue occurs, inspect and trouble shoot according to the corresponding method below.
If the problem is not solved, contact the manufacturer for further instructions or service.

Fault	Cause and elimination method
The massage wheels stop during use (The product beeps and all icons and buttons on the remote controller flicker and then go out.)	As a safety protocol the massage heads will stop if pressure/weight load has exceeded its limit. To avoid potentially over heating or damaging the massage mechanism the chair is designed to automatically shut off if over strained or over heated. The remote will flash a few times and then shut off as a safety measure. If this has occurred turn off the power switch from the back, allow for 30 sec. And power back on. If the weight capacity of 260 Ibs is not exceeded, unplug from the outlet and notify the manufacturer.
The product cannot tilt, or the footrest cannot be raised or lowered (The product beeps, the running light on the remote controller go out and the product stops)	This product will stop upon any obstruction or a too large of a force preventing from operating. If all screen and buttons are flickering and the backrest or the footrest has stopped, tum off the power supply and turn back on 10 seconds. Be sure there are no obstructions in the way of the footrest or the backrest rolling mechanism.
The massage wheels cannot reach the shoulders or the neck	If your head is not properly placed against the backrest during the computer body scan, it may result in an incorrect reading, causing the rollers to start a lower position causing the massage to be inaccurate. If this occurs turn off the power from the remote and start over again to get a proper reading.
The left and right massage wheels have different heights (intensities)	This is a normal function of the massage mechanism as it programmed to massage alternating locations from the right side during certain intervals of the program.
The chair is not functioning (massaging). Upper body (the neck to the waist) massage Lower leg/foot massage	The power line is disconnected. The power switch is not turned on. If no program is selected after turning, the chair will pause and shut down. Turn off and restart.
The roller heads are still warm after turning off the heat or the product is damaged.	Because the roller heads heat up it will take some time for the residual heat to dissipate. If the massage heads are mildly warm, the rollers may be admitting heat created by the friction from the massage.
The power line or the power plug is abnormally warm to hot.	To avoid accidents, contact an authorized service center.

If above solutions are not applicable, kindly refer to "Product Warranty Card" and contact service center.
