Preparing the Camera
• When the camera’s indicator flashes green, the camera is writing, reading, erasing
or transmitting an image to or from the card. Do not perform the following, for
image data may be lost or corrupted:
• Do not apply shocks or vibrations to the camera.
• Do not turn off the power or open the battery cover.
• Do not open the CF card slot cover or remove the CF card.
• Never open the CF card slot cover when the power is on.
• Please note that CF cards formatted in or edited with other manufacturer’s
cameras or application programs may not operate correctly in the camera.
CF Card Handling Precautions
• CF cards are high-precision electronic devices. Do not bend, force, or subject
them to shocks or vibration.
• Do not attempt to disassemble or alter a CF card.
• Moving a CF card rapidly between temperature extremes may cause condensation
to form in the card, leading to potential malfunctions. To avoid condensation
formation, place the CF card in a sealed plastic bag before moving it into a
different temperature zone and allow it to adjust slowly to the new temperature. If
condensation forms on the CF card, put it aside until the water droplets have
evaporated completely.
• Place the CF card in the supplied case for storage.
• Do not use or store CF cards in the following types of location.
-  Locations subject to dust or sand
-  Locations subject to high humidity and high temperatures
Microdrives are a recording medium with a hard disk. Their merits are a large
capacity and a low price per megabyte of capacity. However, they are relatively
more susceptible to vibrations and shocks than CF cards, which use durable
flash memories. Please be careful, therefore, not to subject the camera to
vibrations or shocks when using a microdrive, especially while recording or
replaying.
