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

Check housing is closed
l

l
Check battery and memory card status on the LCD display
l
Check control knob and zoom function
l
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.
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 does 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 6061 Aluminum and Acrylic respectively. 6061 Aluminum is
selected for its outstanding strength stiffness, hardness and toughness, While Acrylic for its crystal clear
transparency and high gloss surface. Both of them have 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 to 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.
Important!!!
For long term storage please remove the main closure o-rings from body.
