PRODUCT STRUCTURE

Operating Principle

Air Compression leg massager consists of an air pump, two solenoid valves, and air compression boots working together as one unit. The air pump is connected to air compression boots via air hoses; each boot has 3 compression chambers.

By inflating and deflating the air chambers through the control of working and/or idle of air pump and solenoid valves at a regular pace and different timing, it is to simulate the kneading, stroking foot/calf and thigh. Software controls the timing and the working and/or idle of air pump and solenoid valves, cycling airflow into and out of the boots to compress body.

• During pregnancy or immediately after birth delivery.
  • Patients with severe blood circulation disorders cannot be used under the above circumstance.
• In addition, if you have a fever or any abnormality in your body, be sure to consult a doctor before use.

B. How many times can I use a day?

- The massager will automatically shut down after 20 minutes of continuous use. We do not recommend that you use the massager for more than 40 minutes in a day. Prolonged use will over-stimulate muscles and nerves and may have adverse effects.

C. Can it be used for other parts than feet, calves, knees and thighs?

- It is only for feet, calves, knees and thighs. Use in other parts may cause accident or injury.

D. What size feet, calves and thighs of users are suitable for?

• Foot width: about 12 cm to about 16 cm.
• Calf diameter: about 16.5 cm to about 24 cm.

E. The strength is too strong or too weak.

- The elasticity can be adjusted by the velcro wrap. When the velcro is loosely wound, the overall use strength and pressure will be relatively weakened. Otherwise, the overall intensity and pressure will be relatively strengthened.

F. The air in the massager hose can not exhaust.

- If a lot of air remains in the airbag, it may take some time to exhaust. Unplug the hose and wait for a while for the air to escape naturally.

G. The following sounds will be heard. Is it abnormal?

1. Velcro sound is crisp

This is the sound of the Velcro slightly opening on the massager (that is the sound of the Velcro being pulled when the air enters the airbag).

Buzzing sound

This is the sound produced by the mode effect.

These are normal which is caused by the product design of the massager.
