Attaching the face cushion to the headset
Before using the headset, attach the face cushion to it first.
Insert the central tab on the face cushion into the slot on the headset, and then align the other face cushion tabs to the remaining slots on the headset frame.
With your thumbs, press these areas on the face cushion.
Hold the headset, similar to the illustration below, and then press down on the marked areas on the face cushion until you hear a soft click.
When you hear the click, this means that the face cushion is now locked to the headset.
