Maintenance

1. Cleaning the Device

Always turn off the device and disconnect all wires before cleaning.
Wipe the device with a soft, damp cloth. Do not use abrasive cleaners or immerse the device in water.
Store the device in its premium carry case when not in use to protect it from dust and damage.

2. Caring for Electrode Pads

After each use, gently peel the pads from your skin.
Place the pads back onto their protective film to maintain their adhesive quality.
If the pads lose their stickiness, gently wipe the adhesive surface with a damp cloth and let them air dry. This can sometimes restore stickiness.
Replace pads when they no longer adhere well to the skin, typically after 50+ uses, or if they become damaged.
