Projector Placement

Attention
The interactive features are operated using infrared communication. Note the
following points when installing the projector.
• Do not install the projector tilted at an angle of 3˚ or more. The interactive
features may not operate correctly.
• Make sure there is no strong light or sunlight shining on the interactive pen
receiver, the projection screen, the projector itself, or the rear of the projector.
• Do not install the projector where it could be subjected to direct sunlight
through a window. This could cause the interactive features to malfunction.
• Install the projector so that the interactive pen receiver is not too close to
fluorescent lights. If the surrounding area is too bright, the interactive features
may not operate correctly.
• If there is any dust stuck to the interactive pen receiver, it could interfere with
infrared communication and the interactive features may not operate correctly.
Clean the receiver if it is dirty.
• Do not put paint or any stickers on the cover of the interactive pen receiver.
• When using the interactive features, do not use an infrared remote control or
microphone in the same room. The interactive pen could malfunction.
• Do not use devices that generate powerful noise, such as rotary devices or
transformers, near the projector, as the interactive features may not operate
correctly.

• We recommend using a smooth, board type screen without any
unevenness. If the projection screen is uneven, there may be
distortions in the projected image.
• Distortions may occur in the projected image depending on the
material of the screen and the installation method.
• When using the interactive features, install the projector so that the
projected screen is a rectangle without any distortion.
• When using the interactive features in the same room as multiple
projectors, interactive pen operations may become unstable. In this
case, connect the optional remote control cable set to the projectors,
and change Sync of Projectors to Wired in the projector's
Pen/Touch menu.

Settings when Using the Touch Unit
When using the Touch Unit, install the projector using one of the following
methods. The Touch Unit cannot be used if another installation method is
used.
• Mount the projector on a wall or suspend it from a ceiling and project
images from in front of the screen (the setting plate or a commercially
available ceiling mount is required).
• Install vertically on a desk and project from the front of the desk (a
commercially available table mount is required).
See your projector's Installation Guide for the Touch Unit installation
methods and angle adjustment methods.
