The label is on the outer side of the headgear. The internal side is smooth, to be comfortable against your face. 4 Thread the top (short) straps through the upper headgear clips (E-1, E-2). 5 Thread the bottom (long) straps through the lower clips (E-1, E-2). 6 Check that the headgear is not twisted.
