Remove the O-ring periodically for inspection. It is not necessary to remove, clean and re-install the
O-ring after every dive provided the O-rings are not become contaminated. As a rule of thumbs set
up the camera and housing before a day's diving. If the housing is required to be opened between
dives for changing memory card or re-charging batteries, make sure the outside of the housing is
thoroughly toweled dry before opening up. After removing the lid and servicing the camera, replace
the lid straight away, rather than leaving it lying around. Before replacing the lid, check the o-rings
and make sure that no contamination such as dust, hair, salt, sand etc. has fallen onto the O-ring or
O-ring recess, as a precaution we recommend to inspect the O-ring every time the lid is opened
and to carry out the maintenance only if necessary.
Procedure
l Place the lid on firm non-slip level surface.
l The O-ring can be extracted using an O-ring extractor tool (make sure the tool has no sharp edges).

to the O-ring. The silicone grease must be evenly distributed round the O-ring.
Replace the O-ring into the groove; run a finger round the O-ring, to make sure it is snugly seated in
the groove.
over the lip.
l Clean the O-ring recess (the square groove
where the O-ring sits) with a cotton bud.
l Inspect the O-ring all the way round its surface
for damage such as cuts tears or contamination.
This should be done visually and also by feeling
the surface texture between finger and thumb.
