Introduction
1.1 Basic information and preparations (continued)
NOTICE
► Intelligent Stack can be only be used with pairs of the same model
projectors.
► A maximum of two projectors can be used in an Intelligent Stack.
► Depending on the installation and surrounding environment, images
projected from the two projectors may not superimpose completely. Images
cannot superimpose well when the screen is slanted, deformed or the surface
is uneven.
• Images projected immediately after turning on the projectors are unstable
due to rising internal temperatures. Wait for a minimum of 20 minutes before
beginning to adjust the superimposed images.
• Image positions may shift due to temperature changes, vibration, or shock
caused from hitting the projector. Install the projectors in a stable environment
when using Instant Stack. If the image positions are shifted, readjust the
images. (

)
• The image positions may shift over time due to the tension and the weight of
the connecting cables. Make sure not to impose any load on the projectors
when arranging the cables.
• If the volume level of the built-in speakers is too high, noise may occur and
the image quality may deteriorate. In this case, check the volume settings on
both projectors.
• When two projectors are connected using an RS-232 cable, the Main
projector will be able to control the Sub projector. This feature is known as
Intelligent Stack. (

) When Intelligent Stack is used with an RS-232 cable,
RS-232 communication cannot be used to control the projector. If you wish to
control the projectors from a computer, use the LAN connection on any of the
projectors.
• When Intelligent Stack is used, the some menu options and settings are
restricted. Refer to this manual for details. (
