1. 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).
2. Do not use lubricants from other brands with the silicone rubber O-
ring on this housing, only use the lubricant provided by NAUTICAM.
3. Discontinue use immediately should you notice any leakage.
4. Store the housing in a robust, shock-proof container during
transportation; avoid transporting with any equipment, such as a
camera, inside the housing.
5. When travelling by air, do not close the housing if the port is
installed, as this may lead to a pressure difference between the
atmosphere and inside the housing.
6. Care must be taken when opening the housing, as pressure may
build up inside the housing which increases the opening force.
7. Do not open the product in a wet or sandy environment. Protect
the interior from moisture and debris in order to prevent
malfunction or leakage.
8. Do not store the product in an environment of high humidity.
9. Do not leave the housing and the camera in direct sunlight for
prolonged periods.

unauthorized disassembling and/or modifications could result in
malfunction or leakage.
