Checking The O-Ring - Fantasea FS-610 Operator's Manual

Notes:
Underwater photographers will probably want to set the flash mode to the
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
no part of it is sticking up or out of the groove. You can then apply a slight layer of silicone if you have not
done this yet. Be sure it is completely seated in the channel for a proper seal.
Lubrication of an O-ring does not improve the seal. It only reduces the
amount of friction on the O-ring when it is being moved into sealing
position. The amount of lubrication required on the O-ring is only enough
Note
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.
1. It is recommended to make some camera settings prior to
inserting camera into the housing. Please refer to the
Coolpix 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
into housing and then take test shots to make sure all
systems are working.
