The pads use 2 different gels. The grid pattern side is more adhesive than the other side. Make sure the grid pattern side sticks to the belt.
When placing the conductive pads on your belt, remove the plastic liner from the grid pattern side first, without touching the geland place them on the belt. Leave them on the belt for about 1 hour which makes them adhere to the belt (this waiting period is not a necessity, but will make them stick better to the belt).
Remove the second plastic liner with the "NO/ON" print and place the belt around your back.
Handclean your belt and let it dry. It is very important that the electrodes are placed on a clean belt.
In case your belt is wet from cleaning or sweating, let it dry completely before placing the electrodes.
Remove the pads from your back and stick them back on your belt.
