How to adjust the focus balance (adjustment by tilting the lens mounter)
When the entire screen surface is not uniform even if the focus has been adjusted, the lens mounter has focus
adjustment screws in three locations.
f Tool used: Hex driver or Allen wrench (diagonal 4.0 mm (5/32"))
f The Allen wrench supplied with the projection lens ET-D75LE6 or ET-D75LE8 cannot be used.
Lens mounter structure
Focus adjustment screws (a), (b), and (c) can be turned to move the lens mount bracket back and forth.
Also, tightening the fixed screws locks the lens mount bracket in place so it does not move.
When a projection lens with a large weight is installed, or when the projector is installed on an inclination, the
lens may tilt and the focus may become unbalanced. In these cases, perform adjustment by referring to the
relationship between the adjustment location and adjustment screws.
