Special note on responsibility for watertight integrity:

Each housing is individually inspected and hydrostatically tested in the factory. The design of the

main piston O-ring seal is among the most reliable in the industry and the watertight integrity is excellent.

This special O-ring design provides a perfect seal even if there is any movement between the body and lid

due to change of ambient pressure. However please note that responsibility for ensuring the integrity of

the watertight seal lies entirely with the user. 10 BAR accepts no liability for damage to, or loss of any

equipment used with, or placed inside the housing. Users are highly recommended to carry out in-water

test of the housings without installing of the camera for their first dive after change of new ports or

alternation of any new configuration. The test can be carried out by lowering the housing with ballast to

the working depth or dive down to the safe diving range.

The O-ring seal is the main barrier between the water outside and the air space within the

camera. 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 providedyou're your

guidance in using and maintaining the O-ring seal.

Maintaining the O-ring Seal:

If the main body to lid O-ring is not installed, install the O-ring before diving. This is the only user

serviceable O-ring. Its care and maintenance is critical to the watertight integrity of the housing. The

O-ring should be replaced at the service interval (see section on service). If the O-ring is contaminated, or

not already installed, inspect grease and install the O-ring according to the following guidelines.

Inspection, cleaning and re-instillation of the O-ring

Tools:

A soft cotton bud or sponge applicator, make sure these are free of all chemicals or

contamination such as loose fibers, and the tube of silicone grease supplied with the housing. Note other

types of silicone grease specifically for use with underwater camera equipment can usually also be used. It

is advised to carry out the following procedure on a firm clean level surface, (e.g. at a table), to prevent

skidding especially useful to have when diving from a boat.

When to maintain the O-ring seal:

Remove the O-ring periodically for inspection. It is not necessary to remove, clean and

re-install the O-ring after every dive provided the O-ring did not become contaminated. As a rule of thumb

set up the camera and housing before a day's diving. If the housing is required to be opened between

dives for changing memory card or re-charging batteries, make sure the outside of the housing is
