Caution for Use
≥
Use only the specified grease. If you use other types of grease, the surface of
the O-ring may be damaged causing water leakage.
≥
The O-ring comes into contact with the sides of the Case making the Case
waterproof. Do not knock, insert foreign materials (dirt, sand, hair etc.) or scratch
the O-ring or sides of the Case.
≥
Use the tips of your fingers to remove the O-ring. Do not use a pointed object as it
may scratch the O-ring.
≥
After removing the O-ring from the rear case, wipe off any dirt, sand, hair or other
foreign materials on it. Also wipe the O-ring groove and the inner sides of the front
case which come into contact with the O-ring.
≥
Never use an O-ring that has been scratched or damaged by dirt etc. This will cause
water leakage. Replace it with a new O-ring.
≥
After replacing an O-ring, not using the Case for a long period of time, opening the
Case to attach a digital camera or to replace the battery etc., thoroughly check that
the O-ring is not scratched or split. Then, close the Case and check that no water
leaks into it by submerging it in a water tank, bath tub etc. for about 3 minutes. (P14)
≥
O-rings are consumable products. Although the lifespan of O-rings will depend on
how well they are maintained, how often they are used and their storage conditions,
we recommend replacing them every year even if you cannot see any scratches.
