Have owned many Hammonds over many years.  Bought an SK2 because it is light for an old guy to gig with.  Seems to be a lemon.  
 
	1, Error message "panel disconnect" comes up - all controls are dead but the organ plays per the sound in use.  Originally a reboot would sometimes fix it but eventually nothing would make it operational again; Replaced main board - happened again today,  
 
	2, At boot up, many times the factory presets will load and not the custom ones I have created - if I tap a preset button it loads the custom ones,  Problem is that all the other custom settings like foot switch control have gone back to factory default also!  grrrrrrrrrrrr
 
	3, Also - if you choose manual mode there is no sound until you move the drawbars for upper, lower and pedals...
 
	Anyone have suggestions?
