All Rights Reserved.(continued on next page)3.7 Important information for Intellectual StackThis section provides important information for setting up the Main and Subprojectors, not explanations on operating the menus. Read all information carefully.● To use Intellectual Stack, one projector must be set to Main and the other set toSub.● When stacking the two projectors, the control panel of the projector placedunderneath cannot be operated. It is therefore strongly recommended to set theprojector underneath to Sub and the projector on top to Main.● All buttons except the STANDBY/ON button on the control panel of the Subprojector are disabled. Operate the projectors with the control panel of the Mainprojector or the remote control.● Pressing the STANDBY/ON button of the Sub projector does not allow you toturn off only the Sub projector. The Main and Sub projectors turn off when thebutton is pressed for more than 3 seconds. And pressing the button does notturn on the Main or Sub projector.● The Main projector is capable of receiving the remote control signals but not theSub projector so the remote control should be pointed at the Main projector.● If a wired remote control is used, connect the cable to the Main projector insteadof the Sub projector.● For simple PC mouse & keyboard functions, connect both the Main and Subprojectors to your computer with USB cables. (Operator's Guide → Using asa simple PC mouse & keyboard)● AUTO SEARCH function is disabled when the projector is used in IntellectualStack.● Network communication to Sub and Web Control on Sub cannot turn on the Subprojector. The Sub projector can only be controlled through the Main projector.● Remote Control function on Web Control of the Sub projector is disabled.(Network Guide → 3.11 Remote Control)● If you try to turn on the projectors using the Power on & Display on feature onthe Messenger function, the projectors will exit Intellectual Stack and display thespecified message.
