Maintenance
Electrode Pad Care
When electrode pads lose adhesion, rinse them with water and scrape off surface residue. Air-dry the pads; adhesion will renew, enabling reuse for 60+ cycles.
Device Cleaning
Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or immerse the device in water.
Storage
Store the device and pads in the provided carrying pouch in a cool, dry place away from direct sunlight.
Troubleshooting
If the device does not turn on, ensure it is fully charged.
If stimulation is weak or absent, check that the electrode pads are securely attached to the skin and that the wires are properly connected to both the pads and the device. Also, ensure the intensity level is not set to zero.
If the pads are not sticking, clean them as described in the "Electrode Pad Care" section.
For any other issues, refer to the detailed user manual provided with the product.
