No.: 
ET
-

D75LE95) is used
After attaching the projection lens, adjust the lens position and the fo\
cus with the projector correctly installed 
against the screen.
The focus balance between the center and periphery of the projected imag\
e will differ depending on the size of 
the projected image when the Fixed-focus Lens (Model No.: ET
-

D75LE95) is attached. Adjust the focus balance of 
the periphery with the Fixed-focus Lens (Model No.: ET
-

D75LE95) as necessary.
1)
 
Move the lens to the ET-
 D75LE95 lens standard position.
 fWhile the shift adjustment screen is displayed, press the  button on the remote control to

Adjustment range by the lens position shift (optical axis shift)
Perform the lens position shift within the adjustment range.
The focus may change when the lens position is shifted out of the adjust\
ment 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

Focus balance
Relationship between the tilt of the lens and the screen focus surface
When the projection lens is tilted in contrast with the image forming surface, tilting the front side (screen side) 
of the projection lens downwards (in the direction of the dotted arrow line), the upper side of the screen focus 
surface will tilt inwards and the lower side will tilt outwards as shown in the example.

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.

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 pro\
jector is installed on an inclination, the 
lens may tilt and the focus may become unbalanced. In these cases, perfo\
rm adjustment by referring to the 
relationship between the adjustment location and adjustment screws.
