It is an effective barrier only if the seal is properly maintained. The O-ring seal should be

inspected before every dive. The following information is provided for guidance in using

and maintaining the O-ring seal.

4.2 Maintaining the O-ring Seal

If the main body to lid O-rings are not installed, install the O-rings before diving. Their care and

maintenance are critical to the watertight integrity of the housing. If the O-rings are contaminated,

or not already installed; inspect, grease and install the O-rings according to the following

guidelines.

opened between dives for changing memory card or re-charging batteries, make sure the outside

of the housing is thoroughly toweled dry before opening up. After removing the lid and servicing

the camera, replace the lid straight away, rather than leaving it lying around. Before replacing the

lid, check the o-rings and make sure that no contamination such as dust, hair, salt, sand etc. has

fallen onto the O-ring or O-ring recess, as a precaution we recommend to inspect the O-ring every

time the lid is opened and to carry out the maintenance only if necessary.
