CP33 globle reset ?

Hi folks,

I'm playing a piano gig in Voss(lovely Norway) for this month of May... they have the standard digital piano in what use to be a nice accoustic piano. This CP33 is doing strange things when I try to change from the initial setup/sound... I'm just trying to use a different sound... but it seems to have a mind of it's own! Is there any way to reset this beast? It's not a bad digital piano, just seems to have a mind of it's own!

Any solutions (yes, I've been trying to google but to no avail using this inhouse/hotel computer) gkeys409@zymondo.com

Thanks!
