To authorize Battery:
Please put in the Battery installation CD and wait till it has appeared
on the screen. (important!)

Then start the application Battery which you have installed on your
disc. You will be prompted for the directory ( you are actually only
being asked to loacate the CD).

Direct the dialog box to the desktop (This is the screen with the two
German buttons), select (i.e.- highlight) the Battery CD (do not double
click it). Then press the "select" button lower right. Done.
