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.

1. Introduction
1.1 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 settings
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.
Operate
the projectors from the control panel of the Main projector or with the remote control
pointing 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 with
the control panel or a wired remote control. KEY LOCK or REMOTE ID * function
is also available. (Operating Guide → OPTION menu)
* Available only in optional remote control.
Tentative terms for the two projectors
For better understanding of the descriptions in this
manual, the following terms are used when explaining
the vertical stacking installation.
Set A : Projector placed underneath
Set B : Projector placed on top of Set A
If you require more information on Instant Stack, please consult your dealer.

CAUTION ► Place the projector in a cool place with sufcient ventilation.
Keep a space of 50 cm or more between a side of the projector and other
objects such as a wall. Take care not to let the hot exhaust air from other
projectors enter the intake vents of the projector.
WARNING ► Take a special care not to fall the stacked projectors.
• When stacking two projectors, make sure the elevator feet and heel of the
upper projector are inserted into the corresponding pockets of the lower
projectors. (

10)
• When using the Instant Stack function by piling up two projectors, you can
change the projection angle by adjusting the
elevator feet of the unit that is placed underneath.
(

7) Exercise care to prevent the stacked projector
from falling off or tipping over while adjusting the
elevator feet.
• A maximum of two projectors can be stacked. Do
not stack three or more projectors.
• Do not install the projectors that are stacked using
the stack pockets, elevator feet and heel of this
projector at a place higher than a person's height.
• Do not install the projectors that are stacked using
the stack pockets, elevator feet and heel of this
projector on a ceiling.
• Do not touch the stacked projectors except when
instructions are given in this manual. Do not hit the
projectors with any type of object.

1.1 Basic information and preparations (continued)
NOTICE ► Intellectual Stack can be operated only in pairs of the same model
projectors.
► A maximum of two projectors can be used as Intellectual Stack.
► Please use the same type of lens for both projectors.
► 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. (
8, 11, 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, 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.
• 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 from a computer, 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. (
