Assembly
Tools Required: None
The communication module and retainer nut should
be checked daily for proper installation and tightness.
The best way to check is by simply loosening the
mount nut by hand (Counter clockwise 1/8 to ¼ turn)
then retightening by hand. Three fingers, is all that is
required. The module does not need to be tightened
excessively to maintain a proper seal.
The entire communications assembly can be replaced
as follows:
1) Slide the earphones out of the retainers.
Remove the earphones from the earphone retainers.
2) Pull the microphone out of the oral/nasal mask.
The microphone must be removed from the oral/nasal mask.
