5. 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.

Check housing is closed

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



Check control knob and zoom function.



If there is a large change of temperature and the housing is not opened for

maintenance between dives, it is recommended to equalize the possible pressure

difference between the inside of the housing and the ambient by opening the

pressure release plug and close it firmly subsequently.

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 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.

5.3.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 gloss surface. 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 recommended to

immerse the housing for 2-3 hours in warm water to dissolve any salt deposits that may have built

up. No chemical cleaners should be used. Mild detergents e.g. shampoo and soap based cleaners

are permitted.

Important !!! Some household chemicals may harm Polycarbonate; the housing should never be
