How do I know if the OptiLife headgear is on correctly, particularly in the dark?
There are two easy ways to identify if the headgear is on correctly. First, feel the top strap. If the headgear is on properly, the attachment tab can be felt on the right side of the top strap. Second, feel the center of the back strap. If the headgear is on properly, the Respironics and OptiLife logos can be felt on the outside of the back strap.
