Recalibration for Z's Deep Click Sensor

Recalibration for Z's Deep Click Sensor

My Swiftpoint Z could not precept its all 5 pressure sensitive buttons correctly, when I press them, they just cannot reach Force 100%. 
I also didn't find any way to recalibrate it neither in mouse's user guide nor X1 control panel.
By the way, where's the control panel's simplified Chinese support?
