Exactly Keith, I'm guessing it's their use that prompted the clause .. a
sort of "not my fault if you have any problems".

My friend uses Rolands EP-5 and EP-9 digital pianos with zero problems
on his home power strips or in any gigs with questionable electrics.
Your friends kit should all be fine, but if he's at all worried, get him
to put it on a filtered mains strip as Keith suggested.
