Data Memory
Permanently stored in non-volatile flash memory every one minute. If power
fails, maximum data loss is less than one minute. Always shut down the LxT
completely before unplugging USB power connections. Otherwise, memory
faults and memory wear may occur more quickly over time. Also, to avoid
creating Flash Memory corruption errors, do not unplug USB drives from the
USB port on the LxT while the drive is being copied, or if the LxT is within
Data Explorer mode.
