Simaudio 600i V2 volume control.

I will contact the seller as well as Simaudio but being a Friday night I thought I would post here to insure I am not missing something. I just purchased a NOS Simaudio 600i V2 integrated and it sounds great and everything seems to be working except,  the volume knob increases the volume turning it clockwise AND counterclockwise. Either direction and the volume goes up. The remote works fine. I am wondering if this might be setting thing. Any Simaudio exerts out there that can help clarify this issue?
