Replace the lid. Remember to ensure the pressure release plug is pulled all the way out while closing, otherwise the air cannot escape. Squeeze the lid closed all the way, you will hear the hiss of air being expelled.

Screw home the pressure release plug. There is no need to excessively tighten this plug. The seal is made by internal O-rings. The O-ring on the underside of the plug is just to keep out dirt.

After replacing 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 0.5-1mm 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. Use & Care of Housing:

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. Most importantly check that the housing is closed, and the pressure release plug screwed home. M ake 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. In case of misalignment of the camera, simply open the case and correct the problem. Check also the battery and film status on the LCD display.

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 few seconds 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. Wear the wrist strap, it is easy to inadvertently let go of the housing, especially if you are distracted.

Cleaning & Storage. The body & lid of the housing are made of polycarbonate. Polycarbonate was selected for its outstanding strength stiffness, hardness and toughness. As well as its crystal clear transparency and high surface gloss. It has good resistance to weathering, although long term exposure to sunlight should be avoided. Normal operating temperature range is 3°C to 36°C (Storage temperature: -10°C to 50°C)

It is good practice to rinse off your housing with fresh water after every dive. Avoid exposure to fine sand. After a series of 10 or more dives, e.g. after a dive holiday, it is re commended to immerse the housing for 2-3 hours in warm water to dissolve any
