8.1 Cleaning Electrode Pads
To prolong the life of your electrode pads:
- Always apply pads to clean, dry skin free of lotions or oils.
- After each use, place the pads back onto their protective film or the included pad holder.
- If pads lose their adhesiveness, gently wipe the adhesive surface with a damp cloth or a small amount of hand sanitizer and let air dry. Do not saturate.
- Replace pads when they no longer adhere well to the skin, as poor adhesion can reduce effectiveness and cause skin irritation.
