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.

4.6 Inspection, cleaning and re-instillation of the O-ring:

Tools:

A soft cotton bud or sponge applicator, make sure these are free of all chemicals or contamination such as loose fibers, and

the tube of silicone grease supplied with the housing are required. Note other types of silicone grease specifically for use

with underwater camera equipment can usually also be used. It is advised to carry out the following procedure on a firm

clean level surface, (e.g. at a table), to prevent skidding especially useful to have when diving from a boat.

When to maintain the O-ring seal:

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-ring did not become contaminated. As a rule of thumb 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, 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 if necessary.

5. Use & Care of Housing:

5.1

Pre Dive Function Check.

Just before entering the water, make a habit of reviewing the proper steps to close the housing and connect

the

bulkhead. Make a visual check of the O-ring seal. It is also useful to switch on the camera, and check that

the

controls e.g. on/off, zoom, shutter functions operate normally.

Check housing is closed

Check O-ring is in the groove between housing and Acrylic

Check battery and memory card status on the LCD display

Check control knob and zoom function

Check the Bulkhead is properly connected or blanked.

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.
