CARE & MAINTENANCE
The Fantasea FA-490/495 housing requires only a minimum amount of care for reliable performance. The
following tips will enable you to get the best results:
1. Always rinse your housing with a strong stream of fresh water and if possible soak the
housing in a fresh water tub or rinse tank for about 20 minutes after every dive in order to
dissolve the salt water crystals from around the controls and openings of the housing.
Manipulate each of the movable controls to assist the removal of salt particles from these
tight areas.
2. Allow the housing to dry thoroughly before packing away for the day or for the trip home.
You may use a soft towel or cloth to dry the housing. Be sure there is no grease or other
debris on the towel.
3. Visually check the condition of the O-ring before every dive. If it is dirty, clean it with fresh
water and dry it with a soft cloth as described above. If it is damaged in any way, such as cut
or perforated, replace it before using the housing again.
4. It is recommended to slightly lubricate the housing's O-ring periodically. It's important to
note that the amount of lubrication required on the O-ring is only enough to allow it to slip
into place without friction, so it does not twist or become dislodged. More grease is not
better, and could in some cases have a negative affect if it is applied in large amounts to
form a build-up that could trap any debris or foreign matter.
5. Be careful not to get greasy fingerprints or dirt on the lens port. This will affect the image
quality. Wipe any dirt or grease off with fresh water and a soft cloth.
6. Do not drop the housing on hard surfaces, it could crack and affect its watertight seal
integrity.
7. Travel with the housing protected in a padded case. It is best to remove the camera from
inside the housing when traveling and provide it with its own protective case, or
compartment.
8. Never dive with the Fantasea FA-490/495 housing to a depth greater than 200 ft/60 meters.
9. It is recommended that you select the shortest time option on the menu, for placing the
camera into standby during periods of inactivity. This will conserve battery power and reduce
