First lay the FPC horizontally on a flat, stable surface, component-side up. Orient the
FPC with the faceplate facing you. Carefully insert the FPC connector edge into the
opening of the bag, and pull the bag toward you to cover the FPC.
CAUTION: To prevent damage when storing FPCs:
Never lay an FPC component-side down.
