FCC INFORMATION (U.S.A. only)

CAUTION:

Changes or modification not approved by JVC could void the user’s authority to operate the equipment.

NOTE:

This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense.

Getting Started

Precautions During Use

Burning-in of D-ILA Device

oDo not allow the same still picture to be

projected for a long time or an abnormally bright video image to be projected

Do not project still images with a high brightness or high contrast on the screen for a long time. This video image could be burnt into the D-ILA device.

Pay special attention when projecting video games and computer program images. Motion images such as normal video playback images do not pose the burning-in problem.

Viewing Conditions (Brightness of Room)

oBrightness of the room

Avoid direct exposure of screen to direct sunlight and lights such as by using a curtain. Images can be well projected by darkening the brightness of the room.

Maintenance Procedures

oClean dirt on the cabinet

with a soft cloth. In case of heavy soiling, soak a cloth in neutral detergent diluted with water, wring dry and wipe, followed by wiping again using a dry cloth.

oPay attention to the following to prevent the

cabinet from deteriorating in condition, getting damaged, or the paint from coming off.

● Do not wipe with a stiff cloth

● Do not wipe with force

● Do not wipe with thinner or benzene

● Do not spray volatile chemicals like insecticide

● Do not allow prolonged contact with rubber or plastic

products

oClean dirt on the lens

using commercial blowers or lens cleaning papers (for cleaning glasses and cameras).

Do not use fluid-type cleaning agents. This may lead to peeling of the surface coating film. Lens surface is fragile. Avoid rubbing it hard or knocking it.

oDo not view screen for prolonged hours

Looking at the screen continually for a prolonged time is tiring to the eyes. Allow your eyes to rest at intervals.

oDo not use this unit when image flickers

due to installation conditions and environment. This may cause your eyesight to deteriorate.

Environment of Use

oDo not use this projector in rooms with

cigarette smoke or oily smoke

Do not use this projector in rooms with cigarette smoke or oily smoke. This may cause the unit to malfunction.

oWhen mounting this projector to the ceiling

Check the temperature around the projector unit. When a heater is in use, the ceiling may reach a temperature higher than anticipated, hence leading to malfunction of the unit.

Gauging replacement time of components

This product comes with replacement components required for maintaining the functions of this product, such as optical components, cooling fan and filters. The timing for replacing components varies considerably according to the frequency and environment of use. For details on replacement of components (except filters), please consult any nearby JVC servicing center.

Installing the Projector and Screen (Cont’d)

 Overlaying projected images

 Projecting images by stacking projectors

The lens shift feature enables you to use up to three stacked projectors at the same time. Stacking projectors enhances the brightness level, and helps to project images that are sufficiently bright even when the venue is relatively big or bright.

 Projecting images by arranging projectors

side by side

The lens shift feature enables you to use up to two projectors that are arranged side by side. Arranging two projectors side by side enhances the brightness level, and helps to project images that are sufficiently bright even when the venue is relatively big or bright. When projecting images by arranging the projectors side by side, adjust the shift amount of both projectors accordingly to superimpose the images.

CAUTION:

●

When the projectors are stacked together during use, ensure that the installation site is sufficiently strong and there is proper air cooling around the projectors.

Take the necessary measures to prevent the projectors from toppling or falling off so as to ensure safety during emergency situations, such as earthquakes, and to prevent accidents from occurring. For details, please consult your authorized dealer.

NOTE:

● When using the projectors by arranging them side by

side, ensure that the installation site is sufficiently strong and there is proper air cooling around the projectors. For details, please consult your authorized dealer. (A Page 11)

Cool down mode

The cool down mode is a function that cools down the lamp for an interval of about 180 seconds after projection ends. This function is to prevent deformation and damage of the internal components of the projector due to heat from the overheated lamp. It also prevents lamp breakage and shortened lamp life.

● When the projector is in the cool down mode, the

[STANDBY/ON] indicator appears blinking in red.

● Do not shut down the main power supply or unplug

the power cord when in the cool down mode. Also, do not block the air inlets and vent holes. Doing so may shorten the lamp life and cause a malfunction.
