Thanks Audrey,

I was aware of the information on page 198 on the Kn7000 manual. But what confused me was that on page 185 of the Kn2600 manual they say that "The BACK UP data will not be erased even with the passage of time." But I think now that this refers to "MIDI (USER for the MIDI PRESETS) & FAVORITES" as previously written in the manual.
