Before using a new microSD memory card (including the card that comes with
the unit), always check that the microSD memory card can be safely read and
written to by the FTC controller.
<How to check read and write operations>
a) Check for correct wiring of power supply to the system. For more
details, refer to section 4.1.
(Do not power on the system at this point.)
b) Insert a microSD 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
microSD memory card cannot be read or written to by the FTC control-
ler.
(6) Make sure to follow the instruction and the requirement of the microSD
memory card’s manufacturer.
(7) Format the microSD memory card if determined unreadable in step (5). This
could make it readable.
