Xinbei** has three modes, which are lactation mode, pumping mode and frequency conversion mode. Below, we will explain the usage and precautions of these three modes in detail. 
First of all, the lactation mode mimics the rhythm of the baby's breast milk, by stimulating the breasts and promoting milk production, helping mothers to breastfeed better. When using lactation mode, the best stimulation can be achieved by adjusting the suction power and massage intensity. It is advisable to start with gentle pressure and gradually increase the intensity when using lactation mode to avoid overstimulation of the breasts. At the same time, the intensity of the massage can be adjusted according to your feelings for optimal comfort. 
Secondly, the pumping mode mimics the baby's sucking action and creates a suction force to pump milk out of the breast. Unlike lactation mode, pumping mode focuses more on the size and duration of suction. When using the pumping mode, it is advisable to choose the appropriate suction size and duration to avoid over-sucking or stimulating the breasts. Generally speaking, the suction power can be adjusted according to the individual's feelings, while the duration can be selected for different time periods according to your needs. Finally, the inverter mode mimics the different sucking rhythms and pressures of babies during sucking, stimulating the breasts by constantly changing the suction and massage intensity, and promoting milk secretion and excretion. When using the inverter mode, it is recommended to start with gentle pressure and gradually increase the pressure and massage intensity to avoid overstimulation of the breasts. At the same time, the intensity and rhythm of the massage can be adjusted according to your feelings for optimal comfort and stimulation. 
To sum up, the three modes of Xinbei ** device have their own characteristics and uses. In the process of use, it is recommended to adjust and choose according to personal needs and feelings.
