My A1000D finally arrived from Japan !

It's gorgeous, and it's everything you can expect from a G : light, comfy, legible, rock solid.

Just one thing, it beeps when switching modes and setting stuffs with the crown. It's not a big deal, but everytime I can, I turn it off (on my GW-3500 or PRW-2000 for example).
I didn't find anything in the operation guide : http://ftp.casio.co.jp/pub/world_man.../en/qw5240.pdf
Is there any way to disable the mode beep ? If not, I'll live with it.

Thanks !
