amount of data, the second option will be a quicker option in

Once the desired set of logs to download have been selected,
press the "Proceed" LSK to start the download process.
Download times are highly dependent on the number and types
of logs being downloaded and the length of time since the last
download. Times can range from a few seconds to more than 15
minutes. The more often logs are downloaded, the shorter the
download times will be.
A progress bar will be presented as the download process
proceeds. As the list is processed, each item will show a status
of
“OK”, “In progress…”, “Pending”, “Skipped”, “Active”, or
“Failed”.
Once the download is complete, press the “Done” LSK to exit
maintenance mode.
When downloaded to the USB fob, the data logs will be saved in
.csv files with a unit n
umber prefix (e.g. “1_” or “2_”). This can be
imported into newer versions of Microsoft Excel
