Batteries
●Use either two lithium battery packs CR-V3 (LB-01 made by Olympus)
or four AA alkaline or lithium or nickel-hydrogen or Nicad 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. If possible,
avoid use of alkaline batteries as they may become exhausted quickly
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.
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.

caught at the O-ring and the contact surfaces.
