<Handling precautions>
(1) Use an SD memory card that complies with the SD stand-
ards. Check that the SD memory card has a logo on it of
those shown to the right.
(2) SD memory cards to the SD standards include SD, SDHC,
miniSD, micro SD, and microSDHC memory cards. The
capacities are available up to 32 GB. Choose that with a
maximum allowable temperature of 55ºC.
(3) When the SD memory card is a miniSD, miniSDHC, mi-
croSD, or micro SDHC memory card, use an SD memory
card converter adapter.
(4) Before writing to the SD memory card, release the write-
protect switch.
(5) Before inserting or ejecting an SD memory card, make sure
to power off the system. If an SD memory card is inserted
or ejected with the system powered on, the stored data
could be corrupted or the SD memory card be damaged.
*An SD memory card is live for a short duration after the
system is powered off. Before insertion or ejection wait until
the LED lamps on the FTC control board are all off.
(6) The read and write operations have been verified using the
following SD memory cards, however, these operations are
not always guaranteed as the specifications of these SD
memory cards could change.

Before using a new SD memory card (including the card that
comes with the unit), always check that the SD memory card
can be safely read and written to by the FTC controller.
<How to check read and write operations>

For more details, refer to section 7.4.1.
(Do not power on the system at this point.)
b) Insert an SD memory card.
c) Power on the system.
d) The LED4 lamp lights if the read and write operations
are successfully completed. If the LED4 lamp continues
blinking or does not light, the SD memory card cannot
be read or written to by the FTC controller.
(7) Make sure to follow the instruction and the requirement of
the SD memory card’s manufacturer.
(8) Format the SD memory card if determined unreadable in
step (6). This could make it readable.
