Hi Tolgay,
I see from your profile that you live in Walnut Creek, CA. I live in the East Bay as well, just a short distance from you. Anyway, I own Tyros2 which I purchased here in the US, and looking at the UL sticker afixed to the bottom of my keyboard, it simply reads:
Yamaha Digital Workstation
Model: Tyros2
120 V
45 W
60 Hz
Made In Japan
Hope that helps.
Scott
