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. Once this test is completed sucessfully, the housing will be 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. Never handle the housing by

grabbing the port or if using one, the Aqua View Finder, make sure that boat crews are familiar with this procedure and advise them to

manipulate only by using the grips provided with the housing. before putting the housing underwater always conﬁrm that your dome or

extension have not rotated accidentally and that it is secured in place as it should be.

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 dried by directing an pressurized 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 two side latches simultane-

ously. 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. Be careful of potential water dripping

on the camera from wet hair, wet suits cuffs or hands..

TRANSPORTING THE AQUATICA Pro Digital housing

Store the AQUATICA 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. The housing is anexcellent protection against water pressure but

direct impact on controls of the housing will be transmitted to the camera with the likelyhood of potential damage.

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 inspect 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 acrylic dome using only products recommended for cleaning acrylic and a soft lint free cloth. same for glass port which should

be cleaned with lens cleaning material only, 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, this may

seriously affect the optical properties of the port. Use of pressurize air from a dive tank is not recommended, the force of the air stream

may easily dislodge a port or O-ring, It is advisable that ports should be removed and serviced after avery dive.
