Are there any chance to disable "Click click" sound in Casio VA-10 (SA-10 etc)?

[Fotoplastikon]

Hey!

I've bought Casio VA10 some time ago.
It's wonderful machine and I'd like to use it on stage... but!...
Yeah. There is a "click click" sound while changing settings (eg. patch number).
It is really annoying... Is there any way to disable this sound?

Thanks for help .

hehe, i remember... that irritating click   and the autopower shut off...
very horrible in a mix. (But the -one channel-vocoder makes it all good again, very beautiful if triggered by drums etc. )
but who knows you could bend the click out.. let me know...
good luck
