The user manual for SX-KN700 is proving to be quite elusive. We're searching for manuals and adding them all the time and I'll let you know as soon as I have it.
However, for now, please take a look at the manual for KN500 which is in the members area. The keyboards are in the same series and functions & instructions should be very similar indeed. I hope that helps you for now, I'll be in touch.
