1.Clean the skin at physio therapeutic part before using the apparatus to prevent dirt from entering into the skin with the ultrasound or compromising the penetrability of the ultrasound. Please remove all metallic objects before the treatment lest unexpected situation impacts curative effects.

2.It is strongly recommended to use medium with certain viscosity to facilitate better fusion between ultrasound and skin and prevent any reflection arising from gap from hampering acoustic and energy absorption.

3.Generally each physical therapy period shall be maintained for 15 to20 minutes, over long time or improper use will cause skin fatigue or bad absorption. The user may select appropriate duration considering the size of physio therapeutic part.
