Charging the Device
Before first use, ensure the device is fully charged using the provided Type-C cable. The device should be turned off during charging.
Connecting and Applying Electrode Pads
- Ensure Device is Off: Always make sure the TENS unit is turned off before connecting or applying electrode pads.
- Connect Lead Wires: Insert one end of the lead wire into either Channel A or Channel B port on the top of the device. Connect the two pins on the other end of the lead wire to the electrode pads.
- Prepare Skin: Clean and dry the skin area where the pads will be applied. Ensure there are no irritations. For optimal adhesion and to prevent discomfort, choose non-hairy areas of the skin.
- Apply Pads: Stick the electrode pads firmly onto the clean skin over the targeted area.
Important: The device will only function correctly when an even number of pads (e.g., 2 or 4) are connected and attached to the skin. If only one or three pads are attached, the current output intensity cannot be increased due to a protective function designed to prevent electrical shock.

Maintenance
Cleaning the Device and Pads
- Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or immerse the device in water.
- The electrode pads are reusable. After each use, gently remove them from the skin (pulling in the direction of hair growth to minimize stress) and place them back on the pads holder or the protective film.
- If the pads lose their stickiness, they can be gently cleaned with a damp cloth and allowed to air dry. Replace pads when they no longer adhere properly.
Storage
Store the device and accessories in the provided storage bag in a cool, dry place, away from direct sunlight and extreme temperatures.
Troubleshooting
- No sensation or weak sensation: Ensure the device is turned on, pads are correctly connected to the wires and device, and an even number of pads are firmly attached to clean, dry skin. Increase the intensity using the A+/A- or B+/B- buttons.
- Device not turning on: Check if the device is fully charged.
- Pads not sticking: Clean the skin area thoroughly before application. If pads are old or dirty, clean them or replace them with new ones.
- Discomfort during use: Reduce the intensity. Ensure pads are not placed over irritated skin or sensitive areas. Consult the user manual for areas to avoid.
For further assistance, please refer to the detailed troubleshooting section in the user manual.
