Olympus CAMEDIA X-350 PT-021 - Manual (Page 5)

Batteries
● Use either one lithium battery pack CR-V3 (LB-01 made by
Olympus) or two AA alkaline or nickel-hydrogen batteries as the
batteries for the camera.
● Alkaline batteries can be used only for a small number of photos,
and their performance also drops with use at low temperatures.
Avoid use of alkaline batteries, as they may become exhausted
during a dive.
● Take care that the battery electrodes do not become wet. This may
cause trouble or accidents.
● Carefully read the instruction manual for the camera about other
cautions regarding batteries.
5. Jumping into the water with the Case in your pocket or in your
hand, throwing the Case from a boat or ship into the water, and
other rough handling may cause water leakage. Please handle with
sufficient care, when handing it over from hand to hand etc.
6. If the camera on the inside should become wet because of water
leakage etc., immediately wipe off all moisture and confirm the
operation.
7. Please remove the O-ring when traveling by air. Otherwise air
pressure may make it impossible to open the Case.
8. For safe use of the digital camera in this product, please read the
"Instruction Manual" for the digital camera carefully.
9. When sealing this product, take sufficient care that no foreign
matter gets caught at the O-ring and the contact surfaces.
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.
