E-4
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
(flat part of the front cover). 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.
