Canon Powershot A590 IS User Manual page 175

Memory cards are high-precision electronic devices. Do not
bend them, apply force to them, or subject them to shocks or
vibration.
Do not attempt to disassemble or alter the memory card.
Do not allow dirt, water or foreign objects to contact the
terminals on the back of the memory card. Do not touch the
terminals with your hands or metal objects.
Do not peel away the original label on the memory card or
cover it with another label or sticker.
When writing on the memory card, do not use a pencil or
ballpoint pen. Only use a soft point pen (e.g. felt-tip pen).
Do not use or store memory cards in the following locations.
• Locations subject to dust or sand
• Locations subject to high humidity and high temperatures
Since some or all of the data recorded on the memory card
may be corrupted or erased by electrical noise, static
electricity, camera or memory card malfunction, making a
backup copy of important data is recommended.
Please note that formatting (initializing) an memory card
erases all data, including protected images.
You are recommended to use memory cards that have been
formatted in your camera.
• The memory card supplied with the camera may be used without
further formatting.
• When the camera is malfunctioning, a corrupted memory card might
be the cause. Reformatting the memory card may solve the problem.
• When a non-Canon brand memory card is malfunctioning,
reformatting it may solve the problem.
• Memory cards formatted in other cameras, computers, or peripheral
devices may not operate correctly in this camera. When that
happens, reformat the memory card with this camera.
If formatting in the camera does not work properly, turn the
camera off and re-insert the memory card. Then turn the
camera back on and format again.
