• Do not operate the flash with dirt, dust or other items stuck
to the surface of the flash.
• Be careful not to cover the flash with your fingers or
clothing when shooting.
The flash may be damaged and emit smoke or noise. The resulting
heat build-up could damage the flash.
• Do not touch the surface of the flash after taking several
pictures in rapid succession.
Doing so could result in burns.
Preventing Malfunctions
• Never place the camera in close proximity to electric motors
or other equipment generating strong electromagnetic
fields.
Exposure to strong magnetic fields may cause malfunctions or
corrupt image data.
• When moving the equipment rapidly from a cold place to a
hot place, you can avoid condensation by placing the
equipment in an airtight, resealable plastic bag and letting it
adjust to temperature changes slowly before removing it
from the bag.
Moving the equipment rapidly from a cold place to a hot place may
cause condensation (water droplets) to form on its external and
internal surfaces.
• Stop using the camera immediately.
Continued use may damage the equipment. Remove the memory
card and batteries or compact power adapter from the camera and
wait until the moisture evaporates completely before resuming use.
