*1 The throw ratio is based on the value during projection of 2.03   m (80") projected image size. When the fixed-focus lens (Model No.: ET- DLE030) is 
attached, it is based on the value during projection of 2.54   m (100") projected image size.
*2
 
When the fixed-focus lens (Model No.: ET-
 DLE030) is attached, the projection relation between the screen and the projector dif fers from that of 
other lenses. Refer to “For fixed-focus lens (Model No.: ET
-

DLE030)” (x
  page   33) for details.
*3
 
When the fixed-focus lens (Model No.: ET-
 DLE055) is attached, the lens shift is not possible, therefore the height position (H) becomes SH/2.

*1 The throw ratio is based on the value during projection of 2.03   m (80") projected image size. When the fixed-focus lens (Model No.: ET- DLE030) is 
attached, it is based on the value during projection of 2.54   m (100") projected image size.
*2
 
When the fixed-focus lens (Model No.: ET-
 DLE030) is attached, the projection relation between the screen and the projector dif fers from that of 
other lenses. Refer to “For fixed-focus lens (Model No.: ET
-

DLE030)” (x
  page   33) for details.
*3
 
When the fixed-focus lens (Model No.: ET-
 DLE055) is attached, the lens shift is not possible. The height position (H) becomes SH/2.

Formula to calculate projection distance per projection lens
To use a projected image size not listed in this manual, check the projected image size SD (m) and use the 
respective formula to calculate projection distance.
The unit of all the formulae is m. (Values obtained by the following calculation formulae contain a slight error.)
When calculating a projection distance using image size designation (value in inches), multiply the value in inches 
by 0.0254 and substitute it into SD in the formula for calculating the projection distance.For PT

Adjusting adjustable feet
Install the projector on a flat surface so that the front of the projector is parallel to the screen surface and the 
projected image is rectangular.
If the screen is tilted downward, the projected image can be adjusted to\
 be rectangular by adjusting the front 
adjustable feet. The adjustable feet can also be used to adjust the projector to be level\
 when it is tilted in the 
horizontal direction.
Adjustable feet can be extended by turning them as shown in the figure.  Turning them in the opposite direction will 
return them to the original position.
Adjustable range
Each adjustable feet: Approx. 30 mm (1-3/16)
Attention
 f Heated air is expelled from the air exhaust port while the lamp is lit. Do not touch the air exhaust port directly when adjusting the adjustable 
feet. (

Attention
 f Replace the projection lens after turning of f the projector. fDo not touch the electric contacts of the projection lens. Dust or dirt \
may cause poor contact. fDo not touch the surface of the projection lens with your bare hands. fBefore attaching the projection lens, remove the lens cover attached to \
the projection lens.
Note
 fIn case of the ultra short focus zoom lens (Model No.: ET- DLE080, ET- DLE085), attachment/removal procedures of the lens mount cover 
are different. Refer to the user manual supplied with ET- DLE080 or ET- DLE085.

Connecting
Before connecting
 fBefore connecting, carefully read the operating instructions for the external device to be connected.
 fT

urn off the power of all devices before connecting cables.
 fT

ake note of the following points before connecting the cables. Failure t\
o do so may result in malfunctions.
 g When connecting a cable to a device connected to the projector or the pr\
ojector itself, touch any nearby 
metallic objects to eliminate static electricity from your body before p\
erforming work.
 gDo not use unnecessarily long cables to connect a device to the projecto\
r or to the projector body

. The longer 
the cable, the more susceptible to noise it becomes. Since using a cable while it is wound makes it act like an 
antenna, it is more susceptible to noise.
 g When connecting cables, connect GND first, then insert the connecting terminal of the connecting device in a 
straight manner

.
 fAcquire any connection cable necessary to connect the external device to the system that is neither supplied 
with the device nor available as an option.
 fIf video signals from video equipment contain too much jitter

, the images on the screen may wobble. In this 
case, a time base corrector (TBC) must be connected.
 f The projector accepts video signals, 

Y/C signals, YC
BCR/YPBPR signals, analog RGB signals (synchronization 
signals are TTL level), and digital signals.
 f Some computer models are not compatible with the projector

.
 f Use a cable compensator when you connect devices to the projector using \
long cables. Otherwise the image 
may not display properly

.
 f Refer to “List of compatible signals” ( x

 
page
 
186) for the types of video signals that can be used with the 
projector.
