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. (6, 8, 11)

•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. (8) 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. (30)
