This marine case is a precision instrument designed to permit safe  
video recording under high water pressure. Please pay careful  
attention when handling the unit before and after use, as explained  
in this users manual.  
Each part of the marine case has been subject to strict controls  
during the manufacturing process, and the individual functions  
have faced stringent tests during the assembly process. Each marine  
case has also had to pass water-proof inspections using high-  
pressure water testers. However, damage can sometimes occur  
during transport and distribution, or during storage after purchase,  
so before diving always carry out the following pre-use test to  
verify safety.  
Also make sure that the inserted silica gel  
bag is not pinched. If you dive with foreign  
matter trapped in these areas, water will  
leak.
