A:
1.Clean the sticky part of the electrodes with clean water. If they don't stick well, use new ones.
2.Before applying the electrodes, clean your skin and avoid using lotions or oils. Shaving the area may help the electrodes last longer.

2.The two electrodes need to be pasted on the skin before the device can output pulses.
3.Check electrode positions and ensure that adhesive electrodes do not overlap.

This indicates low battery. Charge the device for about 2-3 hours with 5V1~2A adapter.

A:
1.The electrodes are not positioned correctly. Check their positions and re-position, if necessary.
2.The electrodes are worn. This may cause irritated skin as even distribution of the current across the entire area is no longer guaranteed. For this reason, replace the electrodes.

A:
Immediately stop treatment and wait until your skin has returned to its normal condition. If the redness is under the electrode and disappears quickly, there is no risk - this is caused by the locally stimulated, increased blood flow. However, consult your doctor before you continue treatment if the skin irritation persists and this is accompanied by an itchy sensation or inflammation. This may be caused by an allergic reaction to the adhesive surface.
