 fWhen removing the batteries, perform the steps in reverse order

.
When using the multiple projectors
When you use the multiple projectors together, you can operate all the projectors simultaneously or each projector 
individually using single remote control, if a unique ID number is assigned to each projector .
When using the projectors by setting the ID numbers, set the ID number o\
f the projector body after initial settings 
have been completed. Then, set the ID number of the remote control. For initial settings, ref\
er to “When the initial 
setting screen is displayed” ( x
  page   61).
The factory default ID number of the projector (projector body and remote control) is set to [ALL], so you can use 
it as it is. Set the ID numbers of the projector body and remote control\
 as necessary.
For details on setting the ID number of the remote control, refer to “Setting ID number of the remote control” 
(x
  page   79).
Note
 f Set the ID number of the projector body from the [PROJECT OR SETUP] menu → [PROJECTOR ID].

Connecting the remote control to the projector with a cable
If you control the multiple projectors with a single remote control, use commercially available M3 stereo mini jack 
cables to connect to the / terminals of the projectors.
The remote control is effective even in places where an obstacle stands in the light path or whe\
re devices are 
susceptible to outside light.

Attention
 f Use a cable that is 15   m (49'3") or shorter, with 2 core shielded. The remote control may not operate when the length of the cable exceeds 
15   m (49'3") or when the shielding of the cable is inadequate.

Usable outlet
This projector supports AC 100 V to AC 120 V, and AC 200 V to AC 240 V as the power supply. A grounded outlet 
supporting 30

Clock position 6h 2P/3W 15 A 125 V
Attention
 f
Use the supplied power cord and ground at the outlet. fUse the power cord matching the used power supply voltage and outlet sha\
pe.
Note
 fThe light output will decrease to approximately 1/3 when using the projector with  AC 100   V to AC 120   V. fThe supplied power cords vary depending on the country or region where y\
ou purchased the product.
Installation mode
The installation modes of the projector are as follows. Set [FRONT/REAR]/[FLOOR/CEILING] in the

Projected image and throw distance
Install the projector referring to the projected image size and projecti\
on distance. Image size and image position 
can be adjusted in accordance with the screen size and screen position. When the Fixed-focus Lens (Model No.: 
ET
-
D75LE95) is attached, the projection relation between the screen and the projector dif fers from that of other 
lenses. Refer to “Fixed-focus Lens (Model No.: ET
-

D75LE95)” (x
  page   38) for details.
 fFollowing illustration is prepared on the assumption that the projected \
image size and position have been 
aligned to fit full in the screen.

Attention
 fBefore setting up, read “Precautions for use” ( x   page   17).
Especially when the Fixed-focus Lens (Model No.: ET- D75LE95) is used, install the projector so that its back plane is parallel to the screen, 
making the projected image rectangular.
The vertical keystone distortion in moderate range can be corrected with the [POSITION] menu  → [GEOMETRY] → [KEYSTONE] → 
[VERTICAL KEYSTONE] (x
  page   99) even after the projector is installed. For the range that can be corrected, refer to “[GEOMETR Y] 
projection range” ( x
  page   39).
 fDo not use the projector and the high-powered laser equipment in the same room.  The DLP

 chips can be damaged if a laser beam hits the 
projection lens surface.
 f The dimension of L4 is not the distance between the rear of the projector body and the wall, but the distance between the rear of the 
projector body and the screen surface. Install the projector with 500

  mm (19-11/16") or larger space between the rear of the projector body 
and the wall or any object so that the ventilation is not obstructed.
When installing the projector in a confined space, provide air conditioning or ventilation separately . Exhaust heat may accumulate when the 
ventilation is not enough, triggering the protection circuit of the proj\
ector.

Note
 f When [GEOMETR Y] is used, the focus of the entire screen may be lost as correction increases. fMake the curved screen a circular arc shape with one part of a perfect circle removed. fAdjustment range of the [GEOMETR

within the projection range, otherwise the correction may not work.
