remote control for at least three seconds.
Adjustment range by the lens position shift (optical shift)
Perform the lens position shift within the adjustment range.
The focus may change when the lens position is shifted out of the adjustment range. This is because the shift
of the lens is restricted to protect the optical parts. Projection position can be adjusted with the optical axis shift
function based on the position of the projected image in the home position (standard projection position) or the
position of the projected image in the ET-D75LE90 lens standard position (reference projection position).
