DATA LOSS
If the SD card is being written to and a voltage drop occurs or
the card is removed, data may be lost or the SD card may be
ruined.

Avoid writing to SD cards. Reasons:
•
SD cards have a limited number of write cycles.
•
If there is a voltage drop while a write operation is in prog-
ress, data loss is highly likely to occur.
▶
Remove the SD card only when the device is de-energized.
▶
Before switching off the device, make sure that there are
no programs writing to the SD card.
