2. Warning
If you are using AC power adapter, unplug the adapter from the AC power
outlet after you have disconnected the camera.
Do not touch the power plug during a thunderstorm if you are using the AC
power adapter. This may cause an electrical shock.
Do not insert or drop metallic or inflammable foreign objects into the
camera through access points such as the memory card slot. This may cause
a fire or an electrical shock.
If the camera has been dropped or if the camera case has been damaged,
turn the camera off and then disconnected the power source (batteries or
AC power adapter). Do not continue to use the camera as this may cause a
fire or an electrical shock.
Do not cover or wrap the camera or the AC power adapter with a cloth. This
may cause heat to build up and distort the case and cause a fire. Always use
the camera and its accessories in well-ventilated locations
Do not use batteries other than those specified for use with your camera.
The use of unsuitable batteries may result in the batteries splitting or
leaking and causing a fire, injury, or soiling of the battery compartment. If
the batteries leak, clean and wipe the battery compartment carefully and
install new batteries.
