Installation
2.3 Installation of the second projector (Set B)
2.
  Keeping Set B on Set A, without 
holding Set B up, push the eleva-
tor buttons of Set B to draw the 
elevator feet.  Make sure that the 
feet are reached to the bottom of 
the stack pockets on Set A.
NOTE  • Keeping Set B slightly away from Set A except the heel part is 
required to avoid sympathetic vibration with the two projectors caused by 
sound out from built-in speakers.
• Be careful that if Set B is tilted more, the image of Set B may not be able to 
be superimposed to the image of Set A.
• If you have already used the elevator feet of Set A, make sure that the angle 
to the horizontal line of both sets should be within 12 degrees.
CAUTION    ►Be  careful  that 
when  you pile  up  two projectors, 
a projector set over the other may 
slide down.
Connecting projectors
If you wish to use Intellectual Stack, connect each CONTROL port on Set A and 
Set B with an RS-232C cross cable.
3.  Make the feet of Set B rotate two 
revolutions counterclockwise to keep about 1 mm space between a protrusion 
at the bottom of Set B and the top case of Set A as shown in the right.
Piling up projectors
1.  Put Set B onto Set A, if you want to pile up two projectors.  Make sure that the  
heel on the bottom of Set B is right into the heel pocket on the top of Set A.
