Setting Up Your Projector - Mitsubishi Electric UL7400U Manual

Setting up your projector

Before setting up
Before setting up the projector, check the operating environment.
If the environmental requirements are not satisfied, the projector may break down or fail.
Setup environment
The allowable operating temperature varies depending on the HIGH ALTITUDE MODE setting.
For use in the STANDARD mode, the allowable operating temperature is +41°F (+5°C) to +104°F (+40°C).
For use in the HIGH ALTITUDE mode (see page 13), the allowable operating temperature is +41°F (+5°C) to +86°F
(+30°C), which allows floor installation or ceiling installation only.
Setting up the screen
Install the screen perpendicularly to the projector. If the screen can not be installed in such a way, adjust the
projection angle of the projector. (See page 13.)
• Install the screen and projector so that the projector's lens is placed at the same height and horizontal position of
the screen center.
• Do not install the screen where it is exposed to direct sunlight or lighting. Light directly reflecting on the screen
makes the projected images whitish and hard to view.
Screen size and projection distance
Refer to the following table to determine the screen size, aspect ratio and projection distance.
• For the aspect ratio setting, see page 24.
• The figures in the tables are approximate and may be slightly different from the actual measurements.
• The lens shift height and width show distances from the factory default position.

• Depending on the installation conditions, warm air that is emitted from the exhaust vents may flow into the intake
vent, causing the projector to display "TEMPERATURE!!" and then stop projecting images.
