Introduction
Notes About Operating Temperature, Humidity, and
Condensation
The operation of this camera has been tested at temperatures from −10°C to +40°C
(14°F to 104°F).
When you use the camera in cold climate regions or at high altitudes, observe the
following precautions.
• Battery performance deteriorates temporarily when cold. Keep the camera and
batteries warm under your clothing before use.
• Camera performance may deteriorate temporarily if it is exposed to extreme cold
for an extended period. For example, the monitor may appear darker than normal
immediately after the camera is turned on, or residual images may be produced.
● Environmental conditions that are likely to cause condensation
Fogging (condensation) may occur on the inside of the monitor, lens, or underwater
lens protector when there are sharp temperature changes or high humidity, such as in
the environmental conditions described below. This is not a malfunction or defect.
• The camera is suddenly immersed in cold water after being in a hot place on land.
• The camera is brought to a warm place such as inside a building after being in the
cold outdoors.
• The battery-chamber/memory card slot cover is opened or closed in a high-
humidity environment.
• The camera or underwater lens protector is wet when the underwater lens
protector is attached.
● Reducing condensation
• Open the battery-chamber/memory card slot cover, put the camera and a
commercially-available desiccant in a container such as a plastic bag, and seal the
container. Condensation is less likely to occur if the humidity inside the camera is
reduced.
• Avoid storing the camera in places where the camera may become hot (such as
places exposed to direct sunlight) before using it underwater. Taking the camera
underwater while it is hot causes condensation due to sudden changes in
temperature.
● Clearing the fogging
• Turn off the camera and open the battery-chamber/memory card slot cover while
in a place where the ambient temperature is stable (avoid places with high
temperature, high humidity, sand, or dust).
To clear the fogging from the lens or monitor, remove the battery and memory
card, and leave the battery-chamber/memory card slot cover open to allow the
camera to adjust to the ambient temperature. When the underwater lens protector
is fogged, remove it.
• If the underwater lens protector is still fogged, try to clear the fogging by removing
the underwater lens protector and using the camera for a while before attaching it
again.
