FOCUS MODE
Make sure to select the focus mode (manual or auto focus) on your camera prior to the dive. The location of
the MF/AF selector on the lens prevent access trough the AQUATICA A40D Digital housing.
AF: The camera will find, lock and hold focus as long as the shutter trigger is partially depressed.
MF: You need to manually adjust the focus. The green dot in the information bar of the camera’s viewfinder
indicates the proper focus setting for the target subject.
For more detailed information concerning the operation of the different focus modes consult the Canon 40D
instruction book.
USING THE HOUSING
Whenever changing ports or O-rings, it is highly advisable to perform a simple seal test without the camera
inside. Strapping a weight to the housing and lowering the unit to a depth of 30 to 50 feet of water for at least
10 minutes will assure you that the seating of the new port or o-ring is proper. This test, though time consum-
ing and often considered unnecessary, may save your camera equipment from irreparable water damage. The
housing is now ready for the dive.
CAUTION:
Never jump into the water with the housing. It is best to have the system handed to you after you have made
your entry, or have it lowered to you on a rope. Make certain that ropes of other equipment stay clear of the
system.
When photographing, be sure to respect the environment. Avoid damaging marine life or manipulating sea
creatures to obtain a pleasing photo. The housing is slightly negatively buoyant so that you can lay it down on
the bottom, but avoid laying it on living coral or other delicate marine life.
Changing the memory card
Always take care to thoroughly dry the housing before opening it to replace the memory card. Wipe the hous-
ing off with a dry towel. If possible it is suggested that the housing be blown dried by directing an air nozzle
around the main o-ring before opening.
Rest the housing on its front with the lens facing down (a dome shade is recommended to protect the acrylic
dome from scratches), release the two latches simultaneously. Lift the rear part of the housing and place it in
a secure location. This minimizes the possibility of any residual water falling into the housing and on to the
camera when the housing is opened or damage to the sealing surface.
TRANSPORTING THE AQUATICA A40D
Store the AQUATICA A40D Digital housing in a sturdy, shock proof container.
When travelling by air, remove or loosen the port. This allows for equalization of the air pressure inside the
housing to the external air pressure. Failure to do so may cause serious damage to the acrylic ports. Avoid
travelling with the camera mounted in the housing. If you must do so, remove the lens as external pressure
can damage the camera.
