Kawai Synthesizers

I'm having a bit of a problem resetting my K3 to the factory
sounds.  The manual says to hold down 'switches 1,2 &3' while 
powering up.  I thought that meant the patch number buttons, but that 
didn't work.  On the K3 group was a post saying to hold down the 
first 3 keys, C, C#, & D, but that didn't do it either!  Anyone have 
any better ideas?  I know you're gonna ask 'why the hell do you want 
the factory settings back?'  I've never heard them, they weren't on 
there when I bought the keyboard & I'd like to see how lame they are,
plus I want to program some new sounds & thought I'd start with the 
factory settings.  Any help would be appreciated.
