Panasonic DLP PT-D3500U - Manual (Page 17)

Setting-up dimensions which are not given in the above
table can be calculated using the formulas below.
LW = 0.03713 x SD – 0.05067
LT = 0.049 x SD – 0.05
(LW,LT: m SD: inch)
For 16 : 9 aspect rations, the following formal can be
used to calculate the screen width (SW).
SW = (SD x 0.0254) x 16 ÷ 337
The value for SW obtained above can then be used
with the following function to calculate the projection
distance for the wide lens position (LW) and the
projection distance for the telephoto lens position (LT).
LW = 1.827 x SW – 0.05067
LT = 2.411 x SW – 0.05

Installation
Projection schemes
Any of the following four projection schemes can be
used with the PT-D3500U projector depending on
user’s needs or viewing conditions.
Use “OPTION2” menu (chosen from the MENU) to
choose the appropriate projection scheme (see
page 35).
Projection Scheme 1
Front projection
Rear projection
Table standing
Projection Scheme 2
Ceiling mount
(Default position)
Installation geometry
After the projector is roughly positioned, picture size
and vertical picture positioning can be finely
adjusted with the powered zoom lens and lens tilt
mechanism.
L : Projection distance
SH : Image height
SW : Image width
H
: Distance from center of lens to bottom edge of
projected image.

Note
• The dimensions in the table above and
the values obtained from the above
formulas may contain slight errors.
• It is recommended that you use the
projection distance for the wide lens position.
• The above dimensions are the case
when the aspect ratio is 4:3. When an
SXGA signal is input and projected, the
right and left ends of the picture will be
blanked the aspect ratio will be 5:4.
Projection distances
Listed in the table below are the projection distances
of the standard lens provided with the PT-D3500U.
Refer to page 61 for the projection distances of the
projection lenses available as optional accessories.
• Do not place or use one projector on top
of another projection unit.
• Install the projector such that the exhaust
port on the rear side is not blocked and a
clearance of more than 30 cm (11
13 / 16 ") is
available.
