Kobelco SK200 Language change.

I am working on a Kobelco SK200 Acera. Ser#YN-24456. I am told this is a grey=market machine. I have an alarm sounding in the cab and hyd functions are causing engine to stall. Original monitor and R/H cosole ctrls were non-op. replaced both but most info is displayed in Japanese. Tried every combo of buttons to no avail.
there are no buttons on monitor itself, just on the console behind the joystick and throttle dial.
