Setup Guide
Charging the Device
Connect the micro USB cable to the charging port on the TENS unit and to a USB power source (wall charger, power bank, or laptop USB). The battery indicator on the LCD screen will show charging status. A full charge can last up to 7 days.
Connecting Electrode Pads
Ensure the TENS unit is turned off before connecting or disconnecting pads. Insert the lead wires into the A1, A2, B1, or B2 output ports on the top of the device. Connect the other end of the lead wires to the electrode pads. Ensure a secure connection.
Applying Electrode Pads
Clean and dry the skin area where the pads will be applied. Avoid applying to broken or irritated skin. Remove the protective film from the gel side of the pads. Firmly press the pads onto the desired treatment area. Ensure full contact with the skin.

Choosing Massage Mode

Adjusting Intensity
Use the intensity buttons (+A/-A for Channel A and +B/-B for Channel B) on the sides of the device to increase or decrease the intensity of the electrical impulses for each channel independently. Start with a low intensity and gradually increase until a comfortable sensation is achieved.
