Installation styles
Following are two styles to install the projectors.  Instant Stack supports both 
styles.  
Style 1 : Stack vertically
Style 2 : Arrange side by side
The descriptions in this manual are mainly on Style  1 installation.  If you wish to 
install two projectors in Style  2, refer to the descriptions required in this manual.
1.3 Basic information and preparations
Instant Stack
Instant Stack is a feature that allows you to superimpose images projected from 
two projectors easily.  This projector is designed to provide this feature, with func -
tions to install two projectors and superimpose the images.
Intellectual Stack and Simple Stack
Instant Stack includes the following two features.  
When two projectors are connected via an RS-232C cable with necessary set -
tings performed on the projectors, these two projectors will automatically operate 
in synchronization with each other according to the settings.  This is known as 
Intellectual Stack in this manual.  
The two projectors operate individually without the RS-232C connection.   This is 
known as Simple Stack in this manual.  
Remote control for Intellectual Stack and Simple Stack
For Intellectual Stack, one projector is set as Main and the other is set as Sub.     
Only the Main projector is capable of receiving the remote control signals.   To op-
erate the  Sub projector, you need to point the remote control at the  Main projector.  
For Simple Stack, both projectors can receive the remote control signals.   To 
avoid crosstalk when operating with the remote control, it is recommended to 
operate one projector with the remote control and the other with the control panel 
on the projector or a wired remote control.  In this case, disable the remote control 
receiving on the other projector with the  KEY LOCK feature. (Operating Guide → 
OPTION menu)

For safety reasons, read 1.2 Important safety instruction carefully before installa -
tion.  In addition, take note of the followings for proper use of Instant Stack.
●
  When using  Intellectual Stack , both projectors will respond to the remote control 
signals until  STACK MODE on either projector is set to SUB.  
During installation, it is recommended to operate one projector with the remote 
control and the other with the control panel on the projector or a wired remote 
control.  In this case, disable the remote control receiving on the other projector 
with the KEY LOCK feature. (Operating Guide  → OPTION menu)
●
  Images from Set A and Set B may superimpose well but the image positions 
can shift over time.   
Readjust to superimpose the images.  
●
  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.  If the 
image positions are shifted, readjust.  
2.1 Preparing for Intellectual Stack
When using Intellectual Stack via RS-232C connection, ensure the following set -
tings are set on the two projectors.  Otherwise, the Intellectual Stack menu cannot 
be operated.
●
  STANDBY MODE in SETUP  menu: NORMAL  
(Operating Guide  → SETUP menu)
●
  COMMUNICATION TYPE under COMMUNICATION in SERVICE menu: OFF  
(Operating Guide  → OPTION menu)
●
  STACK LOCK in SECURITY  menu: OFF
When STACK LOCK is set to on, menus related to Instant Stack cannot be 
operated.  It is therefore necessary to set it to off during installation and menu 
setting.

NOTE
  • Set the tilt angle of Set A to within 12 degrees from the level line.
• Take the followings into account when considering the installation position. 
-  VERTICAL adjuster should be set to the upper limit position.
- ZOOM  ring should not be set to the widest position.
- HORIZONTAL adjuster is recommended to be set near the center position.
Preparing elevator feet
When stacking the two projectors, set the length of the 
elevator feet to the minimum using the elevator but -
tons on Set A and B.
CAUTION    ► Be  careful  when  stacking  the  two 
projectors, the projector on top may slide down.
NOTE  • Cap storage pockets for the pocket caps 
are inside the lens adjuster door.  Be sure to keep 
the caps in the storage pockets after removing the 
caps from the stack pockets.
To store the cap to the pocket, place the thin end of 
the cap into the pocket first, then push the other side 
of the cap down firmly to the bottom of the pocket.  
It is important to ensure that the caps are securely 
stored to prevent children and pets from swallowing  them.

2. Set the lens position to the upper limit with the  VERTICAL adjuster.
NOTE  • If it is not set to the upper limit, the image of Set B may not 
superimpose well enough to the image of  Set A.  
• Perform the MIRROR setting first if necessary as it may change the image 
position. (Operating Guide  → SETUP menu)  
• HORIZONTAL adjuster is recommended to be set near the center position.
3.  Adjust the image of Set A to fit the screen with the VERTICAL adjuster, 
HORIZONTAL adjuster, ZOOM  ring and FOCUS ring. (User’s Manual (con -
cise) → Displaying the picture )   
Adjust the image position using  KEYSTONE and PERFECT FIT if necessary. 
(Operating Guide  → EASY MENU or SETUP menu)
NOTE  • Do not adjust ZOOM  ring to the widest position, otherwise the 
image of Set B may not superimpose well enough to the image of Set A.  Fine 
adjusting the image position of Set  B electrically does not increase its image 
size.  Use the ZOOM  ring to adjust the image size of Set B to slightly larger 
than Set A.  
• KEYSTONE cannot be operated when  PERFECT FIT is in use.  To adjust 
the image using both  KEYSTONE and PERFECT FIT , adjust KEYSTONE 
first.  
• If you are using Simple Stack, go to 2.3 Installation of the second projector  
(Set B).

2.3 Installing the second projector (Set  B) 
2.
  With Set B placed on Set A, push 
the elevator buttons of Set B to 
extend the elevator feet without 
lifting Set B.  Make sure the ele-
vator feet reach the bottom of the 
stack pockets on Set A.
NOTE  • It is necessary to keep Set B slightly away from Set A except for the 
heel portion to prevent the two projectors from resonating due to the sound 
output from the built-in speakers.
• If  Set B is tilt further, the image of Set B may not be superimposed to the 
image of Set A.
• If the elevator feet of Set A are used, make sure the tilt angle for both sets is  within 12 degrees from the level line.
CAUTION    ► Be  careful  when 
stacking  the  two  projectors,  the 
projector on top may slide down.
Connecting projectors
To use Intellectual Stack, connect an RS-232C cross cable between the 
CONTROL port of Set  A and Set B.
3. Rotate the elevator feet of Set B 
twice in the counterclockwise direction and leave a gap of about 1 mm be -
tween the protrusion at the bottom of Set B and the top of Set A as shown in 
the figure.
Stacking the projectors
1. 
Place Set B on Set A when stacking the two projectors.  Make sure the heel 
on the bottom of Set B is inserted into the corresponding pocket on the top of

3. Adjust the image size and position of Set  B with the ZOOM ring, VERTICAL 
adjuster, HORIZONTAL adjuster and FOCUS ring such that the image can be 
superimposed well to the image of Set  A.
NOTE  • Fine adjustment of the image size and position thereafter with 
functions such as KEYSTONE and PERFECT FIT  does not increase the 
image size. It is therefore important to have the image of  Set B completely 
overlapping the image of  Set A.  
• 
When controlling Set B with the remote control, Set A may also respond to the 
remote control.  It is recommended to control Set B with the control panel on Set B.  
• When two projectors are arranged side by side, adjust the image of  Set B to 
superimpose well to the image of  Set A.  
• If you are using Simple Stack, it is recommended to disable the remote 
control receiving on  Set B using KEY LOCK and operate using the control 
panel or a wired remote control as  Set A will respond to the remote control.  
(Operating Guide  → OPTION menu)
• If you are using Simple Stack, go to For Simple Stack users. 
NOTE  • KEYSTONE cannot be operated when  PERFECT FIT is in use.  To 
reset both functions, reset PERFECT FIT  first.
• Perform the MIRROR setting first if necessary as it may change the image  position. (Operating Guide  → SETUP menu)  
2. Reset the adjustment of KEYSTONE and PERFECT FIT  on Set B.  (Operat-
ing Guide  → EASY MENU or SETUP menu)
1. Turn on Set B.
NOTE  • After turning on Set B, make sure the image of Set B is not 
significantly tilted compared to the image of  Set A.  If the image is overly 
tilted, rotate the elevator feet of Set B to adjust the angle such that the tilt is 
just about right.  Check again that there is a gap of about 1 mm between the 
protrusion at the bottom of Set B and the top of Set A.
