BEFORE RECORDING IN WATER
Make sure that the battery cover (page 25) and the terminal cover (page 21)
are closed.
If a cover is open, water will get inside the camera and damage it.
When closing the battery cover and terminal cover, make sure that no foreign
object such as sand, hair, dust, etc. is caught in the rubber seal.
