Page 3: Read This First
Read this first! Always follow these precautions WARNING: Do not look at or place your skin into the light emitted from the lens while the projector is being used. Doing so can cause burns or loss of sight. z Strong light is emitted from the projector’s lens. Do not look at or place your hands directly into this light. -

Page 5: Attaching The Lens / Detaching The Lens
Attaching the Lens / Detaching the Lens Before replacing the projection lens Return the projection lens to the home position before replacing or removing it. For details on how to return the lens to the home position, refer to the operating instructions of the projector. -
Page 6: Making Adjustments
Making Adjustments Correcting the Focus When the projection lens is attached to the projector and images are being projected onto the screen, the peripheral focus may be out of focus in some localized areas. In such cases, use the supplied spacers to correct the focus of these areas, and perform adjustments so that the entire image is even. - Page 7 Making Adjustments (continued) 4) Operate the projector to shift the focus toward the screen a little bit at a time until one of the areas A to D in Fig. 1 just comes into focus on the screen, and then stop. z In this state, the “just focus points”...

Projection relationships The dimensional relationship between the screen and the projector is shown below. ■ Dimensional relationship diagram Projected image L (LW/LT) Screen L (LW/LT) Note z This diagram assumes that the size and position of the projected image will be adjusted so that the image fills the entire screen. - Page 9 Projection relationships (continued) Attention z To prevent blocking of the intake and exhaust vents, maintain clearances from walls and objects of at least 1 000 mm (3'3") for the exhaust vent and at least 500 mm (1'8") for the intake vent. z Avoid setting up in places which are subject to sudden temperature changes, such as near an air conditioner or lighting equipment (studio lamps, etc.).

Page 10: Adjustment Range By The Lens Position Shift (Optical Shift)
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 home position in the respective range. -
