• The operating lifetime of the SD memory card is limited by its
flash memory. After long-term or frequent usage, data reading
and writing capabilities will be degraded. In that case, replace
the card with a new one.
• No compensation is available for loss of data stored on the SD
card, regardless of the content or cause of damage or loss. Be
sure to back up any important data stored on an SD card.
• Observe the following to avoid corruption or loss of stored data:
(1) Do not touch the electrical cont
act
s on the card or inside the
insertion slot with your skin or metallic objects.
(2) While writing or reading data, avoid vibration or shock, and
do not
turn the power off or remove the card from the instru-
ment.
(3) Before formatting (initializing) a
card, confirm that it contains
no important information (files).
(4) Do not bend or drop the card, or otherwise subject it to
in
t
ense shock.
• The SD memory card’s connector is used to judge whether the
card is write-pro
tected. If the write-protected lock is in an inter-
mediate position, the determination of whether the card is write-
protected will dep
end on the connector. For example, even if the
instrument determines that the card is not write-protected and
allows data to be written to it, a computer may determine that it is
write-protected, preventing data from being written to it. If you
are unable to write data to an SD memory card, manipulate fold-
ers and files, or format the card, check the position of the write-
pro
tect lock a
nd disengage it if necessary.
