Note: If the O-ring is in good contact, a thin black line, about 0.5 to 1mm in width
should be visible, where the O-ring is in contact with the lid. Follow this line all
the way round the edge of the seal, as a final check that the seal is good.
The housing is now ready for the dive.
Important !!! Before diving, make sure the pressure release plug is
pushed back inside and then screwed home, do not over tighten this
plug (finger tight only).
