NOTICE  ► Intellectual Stack can be operated only in pairs of the same 

model projectors. (6) 
► 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. (9, 12, 15)  

• 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. (34)   

WARNING  ► When removing the pocket caps from the stack pockets, be 

sure to store them securely and safely inside the lens adjuster door to prevent 

children and pets from swallowing the caps. (3)  If swallowed, consult a 

physician immediately.

CAUTION  ► Be careful not to injure your nail and finger when removing 

the pocket caps. (3)
