- Charger: 100-220V, 50/60Hz, and 10mA (input); DC5V, 300mA (output)


To Operate: 

1. Make sure the power switch of the device is in the OFF position. 

2. Connect a pair of electrode pads to one connecting wire by snapping them on; the other end of the connecting wire is connected to the left output of the device. Similarly, the other pair of electrode pads is connected to the remaining connecting wire and the right output of the device. 

3. Attach one pair or two pair of the electrode pads to the treatment area, such as shoulder or back. 

4. Turn on the device, and both of the left and right outputs stand by. 

5. Pressing the "+" button on the device will increase the intensity of both outputs, and pressing the "-" button will decrease the intensity of both outputs. 

6. Press the "M" button to select a desired stimulation mode. 

7. Pressing the central "►II" button will pause the device; press again to resume. 

8. Pressing the "T" button will select different countdown periods of time from 10 to 60 min. 

9. When done, turn off the device, and put away the connecting wires and electrode pads.

Note: Start from the lowest intensity, and then gradually adjust to a comfortable level on a scale from 1 to 10.

Recommended practices: 

1. Duration of 20 minutes for each body area. 

2. Frequency of 1-2 times per day per area. 

3. Be sure the treatment site is clean of dirt and body lotion. 

4. The lifespan of the electrode pads will vary depending on the use frequency and care taken. Keeping electrode pads clean and sealed in the zip bag after use will extend their lifespan. Replace the electrode pads when they lose their adhesiveness. 

5. Charge the battery of the device by either connecting the USB cable to the device and computer or connecting the USB cable and charger to the device and wall outlet, if the battery indicator on the display indicates a low battery.
