7. Pad Placement Guide

Proper electrode pad placement is crucial for effective stimulation. Refer to the included physical Pad Placement Guide for detailed diagrams. General guidelines include:

Place pads on clean, dry, intact skin.
Position pads around the area of discomfort, not directly over joints or bony prominences.
Ensure pads are not touching each other.
For TENS, place pads to encompass the painful area.
For EMS, place pads over the muscle belly to stimulate contraction.

8. Maintenance

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.

8.2 Device Care and Storage

Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or immerse in water.
Store the device and accessories in a cool, dry place, away from direct sunlight and extreme temperatures.
Keep the device fully charged if storing for extended periods to maintain battery health.

9. Troubleshooting

Problem	Possible Cause	Solution
