1.2 Important safety instruction - For Instant Stack feature (continued)
NOTICE
► Instant Stack is a feature that allows you to stack two projectors
or arrange them side by side easily. Depending on the installation and
surrounding environment, images projected from the two projectors may not
superimpose well enough. The images cannot superimpose well enough
especially 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 temperature. Wait for more than 20 minutes before starting
to adjust the superimposed images.
• The image positions may shift due to temperature change, vibration, or shock
caused by 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, the two projectors may
resonate, noise may occur and the image quality may deteriorate. In this
case, check the volume setting on both projectors. Lower the volume until the
symptoms disappear or arrange the projectors side by side.
• When two projectors are connected using the RS-232C cable, the Main
projector will be able to control the Sub projector. This feature is known as
Intellectual Stack. (

11 ) When Intellectual Stack by means of RS-232C
feature is used, RS-232C communication cannot be used to control the
projector. If you wish to control the projectors, use the LAN connection that is
connected to any of the projectors.
• When Intellectual Stack is used, the operations or settings of some functions
are restricted. Refer to this manual for details. (
