When installing the massage head, it is only necessary to align (match) the massage head with its installation position and directly press in the buckle. Generally, there are four function keys to choose from on the massager, namely, auto, acceleration, deceleration and on/off.
After turning on the on-off key, you can choose to press the automatic key. At this time, you can put the massage head where the body needs massage, let the massager run automatically, and adjust the vibration intensity according to the comfort.
