Thanks Guys:
Thats very good news, I thought I had read about a 5 year battery,Probably was on the old 540 I had for a few weeks....

Gar: I havn't had much luck with getting through to Steve, I was using the telephone, to Yamaha's main number and would get a answer that he would call, problem with this he might not be able to call for a day or so, and each time I was away from the phone. Next time I'll use email.

Thanks to both of you, happy camper on this end.....Pose
