For Instant Stack feature

Introduction

1.2 Important safety instruction - For Instant Stack feature (continued)

NOTICE ► Instant Stack is a feature that brings you a very convenient way to

pile up or line up two projectors. The images projected from the two projectors

may not be able to be nely superimposed on screen depending on the position

or environmental of the projectors. Especially, if the screen is curved or

distorted or unlevel, the images will not be nely superimposed.

• Just after turning on, the projected images will not be so stable since the

temperature inside of the projectors is rising. Wait 20 minutes or more after

turning on, before you start to adjust images to superimpose.

• The images may be shifted by temperature change, vibration and shock of

being hit by something. When you use Instant Stack, install them in stable

environment. If the images are shifted, adjust them again. (

9, 12, 15

)

• The images may be shifted with time by the tension or weight of connected

cables. Pay attention to arrangement of cables not to place burden to the

projectors.

• It may be happened to make a mechanical noise and degrade image quality

by sympathetic vibration with the piled up projectors if the volume of built-in

speakers is set much higher. In this case, check the volume setting on both

projectors, and lower the volume to remove such phenomena or place the

projectors side by side.

• With RS-232C connection between two projectors, a projector as Main can

control the other as Sub, which is a feature called as Intellectual Stack. (

)

If you use the feature, you cannot use RS-232C communication to control

projectors, since RS-232C function is occupied with Intellectual Stack. If you

wish to control projectors, use LAN connection that can be connected with

one of the projectors.

• When you use Intellectual Stack, the operations or setting of some functions

are restricted. Refer to this manual for detail. (

)

WARNING ► Be sure to storage the pocket caps reliably and safely inside

of the lens adjuster door to prevent children and pets from swallowing the caps,

when taking the caps from the in stack pockets. (

) If they swallow the caps,

consult a physician immediately for emergency treatment.

CAUTION ► Be careful not to injure your nail and nger to remove the

pocket caps. (

)

Introduction

Introduction

Tentative naming of two projectors

To be easy to follow the explanation, the following

names are used in the manual for piling up installa-

tion.

Set A : A projector placed underneath

Set B : A projector placed over Set ASet A

Set B

Installation styles

There are following two styles to install two projectors. Instant Stack can support

both of them.

Style 1: Piling them up vertically

Style 2 : Lining them up horizontally

This manual is mainly explained the installation of Style 1. If you wish to install

two projectors in Style 2, refer to the articles you need in this manual.

1.3 Basic information and preparation

Instant Stack

Instant Stack is the feature that brings you very convenient way to superimpose

the images projected by two projectors. The projector is specially designed to

support the feature, and has some functions to support you to install two projec-

tors and superimpose the images.

Intellectual Stack and Simple stack

Instant Stack covers both of the following two features.

If you link two projectors with an RS-232C cable and make necessary setting on

the projectors, the projectors will automatically collaborate to work under the set-

ting. This use is called as Intellectual Stack in this manual.

If you do not connect an RS-232C cable, the projectors will work individually. This

use is called as Simple Stack in this manual.

Remote control for Intellectual Stack and Simple Stack

In Intellectual Stack use, one projector is set as Main and the other is set as Sub.

(

) If you use Intellectual Stack, only the projector as Main can receive the

remote control signal. Even if you want to operate the other as Sub , you need to

point at the Main with the remote control.

If you use Simple Stack, both projectors can receive the remote control signal. To

avoid the operation by the remote control to being mixed up, it is recommended to

operate one projector by the remote control and to operate the other by the con-

trol panel on the projector or wired remote. In this case the other projector should

disable the remote control by KEY LOCK. (Operating Guide → OPTION menu)

Before installation, read carefully Important safety instruction (

3~5

) for safety

reason. And note the followings for proper use of the Instant Stack.

●When you use Intellectual Stack, until you set STACK MODE to SUB on one

projector, both projectors can react to the remote control signal.

For installation, it is recommended to operate one projector by the remote

control and to operate the other by the control panel on the projector or wired

remote. In this case the other projector should disable the remote control by

KEY LOCK.(Operating Guide → OPTION menu)

●Even if the images of Set Aand Set Bare fully superimposed once, it may shift

over time.

Adjust the images again to superimpose the image.

●It may be happened to make a mechanical noise and degrade image quality by

sympathetic vibration with the two projectors if the volume of built-in speakers is

set to much higher.

In this case, check the volume setting on both projectors, and lower the volume

to remove such phenomena. In case the image position is shifted, adjust it

again.

2.1 Preparation with powered up

If you wish to use Intellectual Stack with RS-232C cable connection, the following

setting must be conrmed on both of projectors. Otherwise, menus for Intellectual

Stack on the projectors cannot be operated.

●STANDBY MODE in SETUP menu: NORMAL
