Basic Operation
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 
movement of the lens is restricted to protect the optical parts. Projection position can be adjusted with the optical 
axis shift based on the standard projection position in the range shown in the following figures.

Basic Operation
Adjusting the lens mounter when the focus is unbalanced
▶■Focus balance
▶z
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.

▶■ How to adjust the focus balance (adjustment by tilting the lens mounter)
When the entire screen surface is not uniform even if the lens focus has been adjusted, the lens mounter has 
focus adjustment screws in 3 locations.
▶z
Lens mounter structure
The lens mount bracket can be moved back and forth by turning focus adjustment screws (a), (b), and (c).
Also, tightening the fixed screws locks the lens mount bracket in place so it does not move.

Basic Operation
When a projection lens with a large weight is installed, or when the projector is installed in an inclination, the lens 
may tilt and the focus may become unbalanced. In these cases, refer to Figure 3 and the adjustment examples in 
the table below, and perform adjustments through the following procedures.
▶zAdjustment procedure
1)  
Press the  button or the  button on the remote control on the 
control panel to display the focus adjustment menu.
2)

 
Shift the focus of the entire screen once pressing  ▼.
3)

 
Press  ▲ to stop on any part of the screen to be the first just focus point.
▶z
For the location where focus is shifted in this state, the just focus point is in the inner side of the screen.
4) Loosen the fixed screws in the position relative to the location where the focus is 
shifted the most (the location where the just focus point is shifted the most towards 
the inner side in Step 2)) up to two rotations (see Figure 3).
Attention
 zT

urn screws clockwise in 2 locations, or at least in 1 location to be adjusted.
5) Little by little, turn the focus adjustment screws corresponding to the locations in 
the table below counter clockwise and stop where the image is in focus (
 page 55).
▶zIf the screws are turned counter clockwise, the tilt of the lens will change (see Figure 1) by moving the lens 
mount bracket of the lens mounter forward (screen side), and in the projected image on the screen, the 
adjustment screws and the focus point in the opposite direction will move from the inner side of the screen 
to the outside.
6) Press the  button on the remote control or the  button on the control 
panel to display the shift adjustment menu and reset the screen position of the 
projected image on the screen surface back to an optimal state.
7)
 
Perform focus adjustment again near the center of the screen and if it is still not 
enough, fine tune the amount of rotation of the adjustment screws.
8)

 
When adjustments have been made, securely tighten the loosened fixed screws.
9)

 
Adjust the focus again using the remote control.
▶z Tool used:   Hex driver or allen wrench (diagonal 2.5 mm (0.1"))
▶z
The allen wrench is included with the projection lens ET

-D75LE6, ET-D75LE8.

when DVI-D/HDMI signals are being input. (Automatic 
setup does not work for a movie format signal such 
as an output signal of the blu-ray disc player. ) It is 
recommended to supply images with a bright white
