.1..1. Adjustment Specifications (1) Projector Single Screen Size and Location Specification Defined as the relative position of the two outermost lines for the internal cross-hatch signal and the screen periphery location in the projector single screen size and location specification. [Requirement Specfication] Adjust the screen periphery so it is located between the two outermost internal crosshatch signal lines. However, the third line can be inside the screen periphery. Screen edge Outermost 2 lines 1st line 2nd line (2) Adjacent Screen Misalignment Specification Defined in terms of the degree of internal cross-hatch signal disparity at screen seams. [Required Specification] Line position misalignment d at the seam must be 0 line d 1 line. -Axis Adjustment and Mirror Adjustment Seam misalignment d -2

.1..2. Adjustment Procedure Overview The various distortions do not change in isolation. Rather, they affect one another as they change. Every time the various adjustments are performed, the state of adjustment of all the adjustments performed in the past have to be checked and readjusted as needed. As these repeated adjustments occur over and over, the various distortions are corrected, and at that point the single-screen position adjustment process (-axis adjustment) comes to an end. Next you must check for misalignment between adjacent screens and perform minor adjustments. Also, if there is localized distortion (see graphic), you should adjust the mirror (see.4. Adjusting the Mirror for details on mirror adjustment). Then check for adjacent screen misalignment and Corner is elevated. perform minor adjustments. After adjusting and checking, go on to the next screen. Please note the following items when making adjustments. Warnings (1) Make sure the axis lock screws (4 spots) are loosened, that fastener screws are loosened, and that transport hardware fastenings are released. (2) If when you are turning the adjustment screw you feel it tighten up again or if it won't move at all, immediately stop rotating in the current direction of motion. (You have already exceeded the adjustment range, so continuing to rotate the screw will break the adjustment hardware.) (3) Use the internal cross-hatch signal when making adjustments. Make sure you are at the electrical center point before starting adjustment. [FACTORY ADJ.] [LCOS CONTROL] [PANEL POS] H : 12 / V : 25 -Axis Adjustment and Mirror Adjustment -4

.1..3. -Axis Adjustment.3.2. Detailed Adjustment Hardware Operating Method Refer to the operating guide label (shown belwow) stuck to the back side of the unit while you are operating the adjustment hardware. Warning The screen changes shown on the label illustrate the changes as seen by a person operating the adjustment hardware. Changes as seen by a viewer are reversed. Please be aware of this. Tools Used - Ball-point driver and hex wrench (open: 5mm) Shaft switching lever hardware Warning Carry out the shaft switching operation first as shown below when an adjustment is indicated at the shaft location. <Shaft switching procedure> (1) Lift up the lever hardware. (2) Move the shaft. (3) Lower the lever hardware. -Axis Adjustment and Mirror Adjustment Shaft and adjustment screw Lever hardware -7

.1..4. Adjusting the Mirror The ES50/ES70-11CM is equipped with a mirror adjustment mechanism that provides a means to make localized positional adjustments. This mechanism makes these localized screen position adjustments by pulling and pushing against the mirror. Accomplish this by turning attachment screws located near the spots you wish to adjust. Push Screw : M4 3P screw Push to adjust Pushing the mirror reduces the screen Mirror Pulling the mirror enlarges the screen Pull to adjust Pull Screw: M4 3P bolt (hex head) Adjustment screw side -Axis Adjustment and Mirror Adjustment Warnings Adjacent push and pull screws will not work simultaneously (stopper prevents operation of other screw). If you want to pull after pushing, you have to loosen the push screw. If you want to push after pulling, loosen the pull screw. Mirror adjustment does not necessarily produce the screen changes shown in the illustration. (Example: the screen may change only up and down or left and right, or the area not in contact with the screw may change at the same time.) If this happens, loosen all the mirror adjustment screws and reconsider this as nominal. -9
