Restoring Your Unit to Normal Operation
If you ever encounter major problems with your MaxTester Series unit (for
example, you cannot start it), you can revert your unit to its initial state (as
it was when you purchased it). For current updates, use the Software
Update tool.

The recovery operation cannot be undone or stopped once it is
started.
If you have installed software updates on your unit, you will have to
reinstall them afterwards.
To avoid loosing the data that is stored on the DATA partition (such
as result files or custom background images), you may want to
transfer it to a USB key before restoring your unit. Otherwise, all
your files will be lost.
