Note
When you use a memory card with this product for the first time, it is recommended that
you format the card using the product for stable performance of the memory card before
shooting.
Note that formatting permanently erases all data on the memory card, and is
unrecoverable. Save precious data on a computer, etc.
If you repeatedly shoot and delete images for a long time, fragmentation of data in a file in
the memory card may occur, and movie recording may be interrupted in the middle of
shooting. If this happens, save your images to a computer or other storage location, then
execute [Format].
Memory card formatted with a computer is not guaranteed to operate with the product.
Data read/write speeds differ depending on the combination of the memory card and the
equipment used.
We recommend backing up important data, such as to a hard disk of a computer.
Do not attach a label on the memory card itself nor on a memory card adaptor.
Do not touch the terminal section of the memory card with your hand or a metal object.
Do not strike, bend or drop the memory card.
Do not disassemble or modify the memory card.
