7. Maintenance
7.1 Cleaning the Device
- Wipe the device with a soft, damp cloth. Do not use abrasive cleaners or immerse the device in water.
- Ensure the device is completely dry before storage or next use.
7.2 Electrode Pad Care
- After each use, place the electrode pads back onto their protective film to preserve their adhesive quality.
- If pads lose their stickiness, gently wipe the adhesive surface with a damp cloth and let air dry. Do not use soap or harsh chemicals.
- Replace pads when they no longer adhere well to the skin, as poor adhesion can reduce effectiveness and cause discomfort.
7.3 Storage
- Store the device and accessories in a cool, dry place, away from direct sunlight and extreme temperatures.
- Remove batteries if the device will not be used for an extended period to prevent leakage.
