How Does It Work?

TENS (Transcutaneous Electrical Nerve Stimulation)

TENS are safe, non-invasive, drug-free methods of pain management. TENS is currently one of the most commonly used forms of electro-analgesia. The TENS device relieves pain by sending small electrical impulses through electrodes placed on the skin to underlying nerve fibers.

EMS (Electrical Muscle Stimulation)

EMS, also known as powered muscle stimulator (PMS), is an electrically powered device that repeatedly contracts muscles by passing electrical currents through electrodes contacting the affected body area.

4. Troubleshooting

If your device works improperly, please check below for common problems and the corresponding suggested solutions. If the recommended action does not solve your problem, please contact the seller.

If you feel the intensity changes suddenly and dramatically:

Possible Cause

1. Different areas of your body will react differently. When at a lower intensity, you may not feel the intensity at first. If you continue to increase the intensity rapidly, it may cause the strength to increase suddenly and become unbearable.

Solution: It is recommended that for each increase in the intensity level, feel for 1-2 minutes and then slowly increase the intensity per the situation.

2. Each mode is different. If the frequency or intensity of the mode increases significantly from a lower level during the middle or later stages of the massage, further increases in intensity may be unbearable.

Solution: Be careful to increase the intensity when you feel a significant increase in frequency or intensity in the middle and later stages. If you have a slight discomfort, do not continue to increase the intensity.
