User's Manual (detailed)
Instant Stack Guide
Thank you for purchasing this product.
Features
This projector can be used with another projector of the same model to project an
image on the same screen using the Instant Stack feature.
The two projectors can be operated simultaneously to make the image brighter.
Moreover, if you connect two projectors with RS-232C cross-over cable, it turns to
a kind of intellectual stacking system. The two projectors can work alternately by
themselves, and once one projector has an accident the other voluntarily starts to
work to keep your presentation going.
These features, generically called Instant Stack, provide you with the broad use.

Introduction
1.1 Important safety instruction - Instant Stack feature (continued)
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)
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)

Introduction
1.2 Basic information and preparations
Instant Stack
Instant Stack is a feature that allows you to superimpose images projected from
two projectors easily.
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 details on operating by remote control and from the control panel, refer to 3.7
Important Information for Intellectual Stack.
For Simple Stack, both projectors can receive the remote control signals. To
avoid incorrect operations 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 receiv-
ing on the other projector with the KEY LOCK feature. (Operating Guide →
OPTION menu)
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.
Tentative terms for the two projectors
For better understanding of the descriptions in this
manual, the following terms are used when explain-
ing the vertical stacking installation.

2. Installation
For safety reasons, read 1.1 Important safety instruction (3~5) carefully before
installation. In addition, take note of the followings for proper use of Instant Stack.
● Use the same model projectors.
● Make sure the projection screen is perpendicular to the projectors.
● 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

2.3 Installing the second projector (Set B)
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
Set A.
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.
CAUTION ►Be careful when
stacking the two projectors, the
projector on top may slide down.
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.
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.

Installation
Setting up Set B
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.
2. Reset the adjustment of KEYSTONE and PERFECT FIT on Set B.
(Operating Guide → EASY MENU or SETUP menu)
NOTE • KEYSTONE cannot be operated when PERFECT FIT is in use. To

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.

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.
● When stacking the two projectors, the control panel of the projector placed
underneath cannot be operated. It is therefore strongly recommended to set the
projector underneath to Sub and the projector on top to Main.
● All buttons except the STANDBY/ON 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 STANDBY/ON 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.
● 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. ( Operating Guide → Using as a
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.
● 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 on
the Messenger function, the projectors will exit Intellectual Stack and display the
specified 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.
● The Main and Sub projectors have the following common settings.
- Muting feature ( Operating Guide → Temporarily muting the sound)
- Magnifying feature ( Operating Guide → Using the magnify feature)
- ASPECT and OVER SCAN ( Operating Guide → IMAGE menu)
- COMPUTER IN ( Operating Guide → INPUT menu)
