1 Safety Information / 2 Useful Information / 3 Operating
ŸThis product is not a toy, do not play with the mains lead or hand
controller, there is a risk of strangulation.
2 Useful Information
Lower back pain is one of the most common musculoskeletal
problems in modern society and is experienced by 70% to 80% of
adults at some time in their lives. Massage therapy has the potential to
provide short term pain relief and speed return to normal function.
Potential benefits for back pain sufferers, include:
- Increased blood flow and circulation, which brings needed nutrition
to muscles and tissues. This aids in recovery of muscle soreness
from physical activity or soft tissue injury (such as muscle strain).
- Decreased tension in the muscles. This muscle relaxation can
improve flexibility, reduce pain caused by tight muscles and even
improve sleep.
- Increased endorphin levels: the "feel good" chemicals in the brain.
This mood enhancer can ease depression and anxiety, which can
help reduce pain and speed recovery.
3.1 Removal of the transit screw
There is a screw fitted in the back of the Massager to protect the
mechanism during transit. This MUST BE REMOVED before first use
to allow the shiatsu feature to function. Failure to remove the screw
may cause damage to the mechanism. Use the Allen key provided,
then properly dispose of the screw.
3.2 Using the appliance
Place the Massager onto a suitable chair, slipping the fastening straps
over the back of the chair and adjusting them as required to secure it in
position. Plug into a convenient mains socket, carefully routing the
mains lead so as not to cause a trip hazard.
When first using the product, we recommend trying the short DEMO
program to get a sample of the different features the Massager has to
offer. Thereafter, you can use the remote control to customise your
massage; adding effects such as vibration and heat, or changing the
massage target zone. (See „Device and controls“ for more details).

GB
For best results we recommend using the Back Massager twice a day,
once in the morning and once in the early evening, preferably prior to
eating. Each massage treatment should last for a maximum of 15
mins after which the Massager will automatically switch off.
If the firmness of the treatment causes discomfort, then a towel or
blanket can be placed between the back cushion and your back to
reduce the intensity. The massager also comes with its' own
removable back flap and head rest to add comfort. These can be
removed and washed, following the wash instructions on the label.
If you prefer the treatment time to be less than 15 minutes because the
area is particularly sensitive, you can choose to end the massage at
any time by pressing the Power Button .
Do not exceed 15 minutes use per treatment and 2 treatments per day,
leaving at least 4 hours between treatments.
Always switch off at the mains after use.
