Standard installation dimensions (continued)
Note
z
This illustration assumes that the projector will be installed so that the projected image fills the screen and is
properly aligned with it.
z
This drawing is not in exact scale.
SH
Image height
L4
From screen to rear of projector
SW
Image width
L5
From center of attachment plate to front of projector
SD
Projected image size
A1
From top edge of screen to top of projector
L1
Projection distance (from screen to mirror reflective
surface*)
H1
From bottom of set (the surface in contact with this
product) to top of projector
L2
From screen to tip of lens
L3
From screen to front of projector
* The mirror reflective surface is inside the fixed-focus lens, and is not visible from the outside.
Attention
z
Install the projector with at least 500 mm (19-11/16") gap from the surrounding walls or objects in order to
ensure that the air intake/exhaust ports of the projector will not be blocked.
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.).
z
Regardless of the projector model, set up the projector so that the projected image is rectangular and the
back of the projector and the screen are parallel. Depending on your projector, however, keystone distortion
correction via the [GEOMETRY (2D)] or [GEOMETRY] function may be possible, even after setup.
Refer to the Operating Instructions of ET-DLE030 for details.
Note
z
Dimension L4 is not the distance from the projector rear panel to the wall, but the distance from the projector
rear panel to the screen.
z
When [GEOMETRY (2D)], [GEOMETRY] and [KEYSTONE] are used, distance is corrected to become smaller
than the specified image size.
z
The illustrations of projectors in this manual are for informational purposes only and do not represent a specific
model. Configurations may vary with the model.

L1, A1 calculation formula
(Unit: m)
Check the projected image size SD (m) and use each formula to determine projection distance (L1) and top of set
to top edge of screen (A1).
By determining L1 and A1, you can calculate all other dimensions.
(Values obtained by the calculation formulas 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.
In the case of PT-RZ770 / PT-RZ660 / PT-RZ970 / PT-RZ670 / PT-DZ870
For 16:10 aspect ratio
For 16:9 aspect ratio
For 4:3 aspect ratio
L1
= 0.3205 × SD + 0.0047
= 0.3294 × SD + 0.0047
= 0.3628 × SD + 0.0047
A1
= 0.1977 × SD - 0.0721
= 0.2304 × SD - 0.0721
= 0.2238 × SD - 0.0721
In the case of PT-RW730 / PT-RW620 / PT-RW930 / PT-RW630 / PT-DW830
For 16:10 aspect ratio
For 16:9 aspect ratio
For 4:3 aspect ratio
L1
= 0.3365 × SD + 0.0047
= 0.3459 × SD + 0.0047
= 0.3809 × SD + 0.0047
A1
= 0.2597 × SD - 0.0740
= 0.2942 × SD - 0.0740
= 0.2941 × SD - 0.0740
