After replacing and locking the lid, make a final visual inspection of the main O-ring for
contamination.
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.

Use & Care of Housing
5.1 Pre Dive Function Check.
Just before entering the water, make a habit of reviewing that you have carried out the proper
steps to close the housing and the bulkhead is connected. Make a visual check of the O-ring seal.
It is also useful to switch on the camera, and check that controls e.g. on/off, zoom, shutter
functions operate normally.
l
Check housing is closed
l
Check O-ring is in the groove between housing and Acrylic
l
Check battery and memory card status on the LCD display
l
Check the shutter release, control knobs and zoom function.
Always avoid submerging the housing in hot water for a prolonged time or a
cleansing
tank where the water may be heated up by the sun.
5.2 General Operation.
The control levers and push buttons consist of internal double O-ring seals on a stainless steel
shaft. This arrangement is very reliable, however as a precaution, when operating the controls,
avoid excessively rapid movements, as this may distort the O-ring. Also please allow for the fact
that the camera takes a while to power on. If the camera dose not appear to respond to a control
action, make sure that no other controls are pressing on the camera, i.e. locking out further
actions.
