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.

Adjustment procedure
1) Press the <FOCUS> button or the <LENS> 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 rst 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 xed 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
z
Turn 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).
z
If 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 <SHIFT> button on the remote control or the <LENS> 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, ne tune the amount of rotation of the adjustment screws.
8) When adjustments have been made, securely tighten the loosened xed screws.
9) Adjust the focus again using the remote control.
