(the location where the just focus point is shifted the most towards the inner side in Step 2)) up to two
rotations.

If the screws are turned counterclockwise, the tilt of the lens will change by moving the lens mount bracket
of the lens mounter forward (screen side), and in the projected image on the screen, the focus point in the
opposite direction of the adjustment screws 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 lens 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 fixing screws.
9) Adjust the focus again using the remote control.
