Canon FA-480 manual Notes, Checking the O-RING

1.Mount the camera on the removable tray, using the tripod screw.

2.Slide the tray and camera into the housing tray slot. Make sure it is completely inserted.

3.Make sure the camera lens is more or less centered in the rounded port area and that the lens does not distort the round black rubber seat. The housing is designed to have the camera fit in place perfectly, but if you are not careful, it is possible to put it in at an improper angle and it will then be impossible to get a good seal or easy closure of the housing.

4.After camera insertion, check that the extended camera lens does not catch or bend the black rubber seat on the inside of the lens port. It is vital that the lens does not disturb this rubber seat.

Notes:

1.It is recommended to make some camera settings prior to inserting the camera into the housing. Please refer to the PowerShot owner's manual for menu options and personal preferences.

2.Take a few test shots: it is recommended to turn the camera "on" and program to “Flash Always” mode before inserting it into the housing and then take test shots to make sure all systems are working.

Underwater photographers will probably want to set the flash mode to the Flash Always setting to ensure that they always have a flash with every exposure. It is also wise to set the focus mode to allow the lens to focus in the macro range for capturing great images of the tiny and exotic subjects that you can find underwater.

CHECKING THE O-RING

Prior to each closure of the housing the O-ring should be visually inspected. If there is any debris present, including dirt, sand, dust, hair, grease or other matter, it must be cleaned to ensure a proper watertight seal. Cleaning the O-ring is a simple matter of wiping it with a damp, soft cloth to remove the foreign matter. Be careful the cloth you use does not leave any of its own material behind as this can also affect the effectiveness of the seal. When replacing the O-ring, place it back into the groove starting at one corner and gently place it in by pressing it into the groove all around the housing until it is all sitting in the groove and
