3.7 Important information for Intellectual Stack  
This section provides important information for setting up the Main and Sub 
projectors, 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 to 
Sub.
● All buttons except the 67$1'%<21 button on the control panel of the Sub 
projector are disabled.  Operate the projectors with the control panel of the Main 
projector or the remote control.
● Pressing the 67$1'%<21 button of the Sub projector does not allow you to 
turn off only the Sub projector.  The Main and Sub projectors turn off when the 
button is pressed for more than 3 seconds.  And pressing the button does not 
turn on the Main or Sub projector.
● The Main projector is capable of receiving the remote control signals but not the 
Sub projector so the remote control should be pointed at the Main projector.
● <Only for &3;, &3:; and &3:8>
Each Status Monitor can also be operated individually from the respective 
control panel of the Main and Sub projectors. Only the monitor on the projector 
that has been turned on can be operated with the remote control.
● If a wired remote control is used, connect the cable to the Main projector instead 
of the Sub projector.
● For simple PC mouse & keyboard functions, connect both the Main and Sub 
projectors to your computer with USB cables. (

simple PC mouse & keyboard
)
● AUTO SEARCH function is disabled when the projector is used in Intellectual 
Stack.
● Network communication to Sub and Web Control on Sub cannot turn on the Sub 
projector.  The Sub projector can only be controlled through the Main projector.
● The Web Remote Control function of the Sub projector is disabled. (

Guide → 3.1.11 Remote Control)
● If you try to turn on the projectors using the Power on & Display on feature on 
the Messenger function, the projectors will exit Intellectual Stack and display the 
specied message.  To start Intellectual Stack again, re-select MAIN/SUB on 
both projectors in the STACK MODE dialog, or turn off and on both projectors 
again.
