For Prevention of Water Leakage Accidents
When water leakage occurs while this product is being used, repair of the camera housed in
this product may become impossible. Please observe the following cautions for use.
1. When sealing this product, make sure that no hairs, fibers, sand particles or other
foreign matter stick not only to the O-ring, but also to the contact surface. Even a single
hair or a single grain of sand may cause water leakage. Please check with special care.
2. The O-ring is a consumption product. Please replace it at least once a year by new one.
Also perform maintenance for every use.
3. Deterioration of the O-ring will progress according to the use conditions and the storage
conditions. Immediately replace the O-ring by a new one if it is damaged, shows cracks, or
has lost its elasticity.
4. At the time of O-ring maintenance, clean the inside of the O-ring groove and confirm the
absence of dirt, dust, sand, and other foreign matter.
5. Apply the specified silicone O-ring grease to the O-ring.
6. The waterproof function is not effective when the O-ring is not installed correctly. When
installing the O-ring, take care that it does not project from the groove and that it is not
twisted. Also, when sealing the Case, close the lid after confirming that the O-ring has
not come out of the groove.
7. This product is an airtight construction made of plastic (polycarbonate). When it is left for a
long time in a car, on a boat, at the beach, or at other places reaching a high temperature, or
when it is subjected for a long time to uneven external force, it may be deformed and the
waterproof function may be lost. Pay sufficient attention to temperature control. Also do not
place heavy objects onto the product during storage or transport, and avoid unreasonable
storage.
8. When the O-ring contact surface is pressed strongly from the outside of the Case, or
when the Case is twisted, the waterproof function may be lost. Take care not to exert
excessive force.
9. Please be sure to perform the advance test and the final test each time before using the
case.
10.If you should notice drops of water or other signs of water leakage while taking pictures,
immediately stop the dive, remove any water from the camera and the product, test
according to the item "Final check", and confirm whether leakage has occurred or not.
