Figure 76: Do Not Carry an FPC with Only One Hand
• Do not rest any edge of an FPC directly against a hard surface (see Figure
77 on page 146 ). If you must rest the FPC temporarily on an edge while
changing its orientation between vertical and horizontal, use your hand as
a cushion between the edge and the surface.
