Hi tester, I know I'm late to the party, but I've got a question- do you know of any other sources for Cyberpower service manuals? I've got a unit that I just can't crack the case on- literally! From day one, it's had an F04 fault, and it's probably (hopefully) similar to your issue- but I can't get the damn case open! Close, but the bottom seam just won't open, and I'd really rather not break it apart.
Thanks in advance if you can help- and thanks anyway if you can't!
Max
