RECAUTIONS
•A water-tight test without the camera inside the housing is highly recommended
when using the system for the first time and after the changing of port and O-ring(s).
•Do not use lubricants from other brands with the silicone rubber O-ring on this
housing, only use the lubricant provided by NAUTICAM.
•Discontinue use immediately should you notice any leakage.
•Store the housing in a robust, shock-proof container during transportation; avoid
transporting with any equipment, such as a camera, inside the housing.
•When travelling by air, do not close the housing as this may lead to a pressure
difference between the atmosphere and inside the housing.
•Care must be taken when opening the housing, as pressure may build up inside the
housing which increases the opening force.

moisture and debris in order to prevent malfunction or leakage.
