The mask is carried in the mask carrying case.
WARNING!
Ensure that the top of the mask seal only lies on the user's forehead. Hair should not be between the mask's seal
and the user's skin.
The mask could otherwise leak. This danger also exists for instance for mask wearers with beards or deep scars in
the sealing area.
Failure to follow this warning can result in serious personal injury or death.
3.1 Donning the Mask
WARNING!
In order to guarantee a proper fit for those wearing glasses, the 3S Full Face Mask spectacle kit must be worn
according to the relevant user instructions, since ordinary glasses cannot be worn under the mask.
Failure to follow this warning can result in serious personal injury or death.
3.2 Leak Check
