Emu XL-7 & MP-7 User's Group

What is the command sequence for doing a factory reset?
I didn't see it in the manual.

Will this initialize all of the sequences/patterns?
Or is there another way to do this?
Will it have any effect on the user bank of arpeggiator patterns?

If possible, I would like to erase all of the sequences, but keep the 
user arps.

Thanks
