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.
