Aquatica Nikon AD80 - Manual (Page 12)

FOCUSING MODE
NOTE : Select the proper focus mode using the AF / M selector or the optional A/M selector on macro lenses. For more
detailed information concerning the operation of the different focus modes consult the Nikon instruction book for the D80
camera.
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 consuming 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 change memory card. Wipe the housing 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, be carefull to protect the port surface, release the top
latch first then the two side 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 Pro Digital housing
Store the AQUATICA Pro 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, re-
move the lens as external pressure can damage the camera.
CARE AND MAINTENANCE
Of the housing:
After each and every salt water dive, your housing system should be soaked or rinsed in fresh water. The housing system
should soak in fresh water for at least 30 minutes. During this soaking period reach into the water and operate all the
controls several times.
Be sure to remove the housing’s main o-ring and clean it after every use. Refer to Maintenance: Of the O-rings. To ensure
that the hand grips won’t fuse on to the housing due to the exposure to salt water, it is also a good practice to occasionally
remove the hand grips. Clean and lubricate the bolts with a small amount of WD-40.
WARNING: Use WD-40 carefully, sparingly and only on metal to metal surfaces. WD-40 can damage the acrylic on the
ports, the optical surfaces on lens as well as the O-rings.
Of the Ports:
Care should be taken with the Dome Port and Macro Port to avoid scratches on the lens surface. The acrylic port is softer
than glass so minor exterior scratches are often unavoidable. However, since the indices of refraction for acrylic and water
are almost equal the scratches will not seriously impair image quality. Internal scratches(air side) must be avoided as they
do not fill in with water and will affect the quality of the image.
Clean the dome using only products recommended for cleaning acrylic and a soft lint free cloth. Dust on the interior surfaces
of the port can be removed with a soft camel hair brush or a blower brush. Caution must be taken when using aerosol
devices as not to spray the lens material with the liquid propellant as this may seriously affect the optical properties of the port.
The ports should be removed and serviced after avery dive.
