Cleaning and storing pad

Clean: After using pads on your body, please drop a little clean water on the sticky side and use fingertips to clean it softly

• Please turn off the device and disconnect the pads with wires first before you clean the pad.
• Do not use nails or other sharp objects on the sticky side.Do not use chemical liquids on sticky side.

Storage: Place pads on pad holder or place plastic film on the sticky side of pad to keep the gel moisture.

• Do not keep device in areas subject to direct sunlight, high or low temperatures, humid area, near to fire, vibration, or shock.

WARM TIPS FOR SKINCARE

To avoid skin irritation, especially if you have sensitive skin, follow these suggestions:

1. Wash the area of skin where you will be placing the electrodes, using mild soap and water before applying electrodes, and after taking them off. Be sure to rinse soap off thoroughly and dry skin well.
2. Excess hair may be clipped with scissors; do not shave stimulation area.
3. Wipe the area with skin preparation wipes. Let the area dry.Apply electrodes as directed.
4. Many skin problems arise from the “pulling stress” from adhesive patches that are excessively stretched across the skin during application. To prevent this, apply electrodes from centre outward; avoid stretching over the skin.5.To minimize “pulling stress”, tape extra lengths of lead wires to the skin in a loop to prevent tugging on electrodes.
5. When removing electrodes, always remove by pulling in the direction of hair growth.
6. It may be helpful to rub skin lotion on electrode placement area when not wearing electrodes.
7. Never apply electrodes over irritated or broken skin.
