4 APPLICATIONS

4.1 BATTERY_TEST (ALL MODELS)

Recorder battery test Player battery test
This plugin simulates normal power drain by spinning up the disk and reading a big file
once ever 90 seconds (or thereabout). Each spin up also writes the battery level to a
log file. The test stops when battery level reaches 4% in order to avoid being unable
to write to the disk. The power usage data is saved to a file in the root directory of
the Jukebox. This plugin can sometimes be useful for diagnosing problems with
battery charging.
