CF Cards
(1) CF cards are precision appliances. Do not subject the card to physical shock or vibration.
Doing so may destroy the data it contains.
(2) Do not store or use a CF card near anything having a strong magnetic field such as a
magnet or in places prone to having static charge. Doing so may destroy the image data.
(3) To prevent deformation due to heat, do not leave any CF cards in direct sunlight or near a
heat source.
(4) Do not spill any liquids on the CF card.
(5) To protect the data, be sure to store the CF card in the dedicated case.
(6) A CF card incompatible with the camera will not be able to record or display any images.
Be sure to use only compatible CF cards.
(7) Do not bend or exert any excessive force or physical shock on the CF card.
(8) Do not store CF cards in hot, dusty, or humid places. Also avoid places prone to generate
static charge or an electromagnetic field.
