Hi and welcome to Beoworld
First, don't force the front panel unnecessarily. If you have to open it and it won't respond to the push button, the best thing to do is remove the top cover and release the latch from the inside. Then leave the control panel open until you have fixed your problem.
I can email you 10Mb of files with the information that you want but I will have to send it to your private email address. Pse PM or send me your email address so that I can send you the files.
Regards
Geoff
