of use on shoulder and abdomen
·It is provided with a unique shawl assembly, with innovative heating functions on
the shoulder, back, waist and abdomen and heating with graphene. Users can
place the shawl at different massage positions according to massage
requirements. When the shawl assembly is placed at the shoulder position, it will
heat the acupoints such as Bingfeng, Tianzong, Yunmen and Qihu around the
shoulder and clavicle by graphene heating, effectively relieving symptoms such
as scapulohumeral periarthritis and cough, and removing cold and moisture from
shoulder joints.
·When the shawl assembly is placed on the abdomen and back (dual-purpose),
through graphene heating, it plays the role of dispelling cold and relieving pain,
warming channels and removing blood stasis in the back and abdomen,
distributing Qi and blood of the back and abdomen meridian, alleviating the
symptoms such as irregular menstruation and dysmenorrhea for women, relieving
low back pain and kidney discomfort, warming intestines and stomach and
clearing intestinal cold, with a good effect on some people with deficiency of qi and
deficiency of spleen and stomach.

Troubleshooting
Solution
Fault
When the calf mechanism or the backrest reaches a certain position,
press the corresponding adjustment button and it will no longer change,
and a continuous "beep, beep" sound will be emitted.
Due to product structure design and ergonomic requirements, this product
has a limited protection design for the limit state of attitude adjustment.
At the same time, a reminder sound will sound when the limit is reached.
Solution
Fault The function does not work or some functions do not work after the
machine is turned on.
After the machine is turned on by pressing the switch key, it is necessary
to manually select an automatic massage program or other working state.
If it is not operated, the machine will automatically shut down after 20
minutes. If the manual operation mode is selected, the functions that are
not selected may be disabled, and the working mode needs to be
manually set in the manual mode.
Solution
Fault The machine makes a leather rubbing sound when adjusting its posture.
This product adopts high-grade anti-corrosion leather that meets
environmental protection requirements. Due to the inherent characteristics
of leather materials, there will be a normal slight noise when rubbing at
the relative movement, which is a normal phenomenon. Note: If you hear
fabric or leather tearing sound when the machine is running, please stop
using it immediately and seek professional maintenance.
Solution
Fault The massage wheel did not reach the shoulders or neck.
If the head does not touch the head cushion or the back does not touch
the backrest, the shoulder position may be lower than the actual position
during the body shape detection process. Sit in the deepest position of the
seat, rest your head on the headrest, and start over from the beginning.
Solution
Fault The unit is damaged.
The power cord or power plug is abnormally hot.
To prevent accidents, be sure to contact an authorized service center.
Please feel free to contact the designated service personnel for any questions or
doubts about this product.
