Precautions on handling

Precautions on transport

The projection lens is susceptible to vibrations and
impacts. Care should be taken to protect the lens from
vibrations and impacts when transporting.

Precautions on installation

Be sure to observe the following precautions when
installing the product.

Avoid installing the product in a place
exposed to vibrations or impacts

.

If the projector is installed in a place where
vibrations are transmitted from a source of
driving power and others or mounted in a car or
a vessel, vibrations or impacts may be
transmitted to the product to damage the internal
parts, causing failure. Install the product in a
place free from vibrations and impacts.

Do not install the projector near high­voltage power lines or power sources.

The product may be exposed to interference if it
is installed in the vicinity of high-voltage electrical
power lines or power sources.

Do not place the projector on a vinyl
sheet or carpet.

If a vinyl sheet sucked up and blocks the air filter
intake port, the internal temperature of the
projector may increase, which triggers the
protection circuit, turning off the power.

Be sure to ask a specialized
technician when to install the
product to a ceiling.

If the product is to be installed hanging from the
ceiling, purchase an optional hanging attachment
(for high ceiling: Model No. ET-PKD75) (for low
ceiling: Model No. ET-PKD75S) and call a
specialized technician for installation.

Do not place the projector over 2 700 m
(8881.5') above sea level. When using it
over 1 400 m (4605.3') above sea level, set
the “Fan Control”, described on page 73,
to “HIGH”.

Otherwise the life of the product may be shortened.

Precautions on use

To view clear images:

• The audience cannot enjoy high-contrast and
clear images if outside light or the illumination
interferes the screen surface.Draw window
curtains or blinds, turn off the lightings near the
screen or take other proper measures.

• In rare cases, wafture can occur on the screen
affected by the warm air from the exhaust port
depending on the environment.

Do not touch the surface of the
projection lens with bare hand.

If fingerprints or stains are left on the projection
lens surface, they are magnified and projected
on the screen. Keep your hands away from the
lens. Cover the lens with the supplied lens cap
when the projector is not used.

Screen

If the screen has stains, flaws or discoloration,
clear images cannot be viewed. When handling
the screen, be careful not to apply volatile
substances or leave flaws or stains on the screen.

Lamp

A mercury lamp with high internal pressure is used
for the light source of this product. A high-pressure
mercury lamp has the following characteristics:

• It may burst with a loud sound or end its life
cycle by not illuminating because of given
impacts, flaws, or deterioration due to used
hours.

• The life cycle of a mercury lamp varies according
to the individual difference or conditions of use.

• In rare cases, it may burst shortly after the first
lighting.

• The possibility of burst increases when the lamp
is used beyond the replacement time.

Disposal

To discard the product, call the dealer or a specialized
dealer

Cleaning and maintenance

Be sure to remove the power cord plug from the receptacle before cleaning.

Use soft and dry cloth to clean the cabinet

If stains are hard to remove, use a cloth dampened with a kitchen detergent solution (neutral) and squeezed
to wipe the cabinet and finish with a dry cloth. If a chemical wipe is used, follow its instructions.

Do not clean the lens surface with fuzzy or dusty cloth.

If dust adheres to the lens, it will be magnified and projected on the screen.
Use a soft and clean cloth to wipe off dust.

Loading dry cells

When loading supplied AA dry cells into the battery
compartment of the remote control, make sure that
their polarities are correct.

1. Open battery compartment lid.

Open the lid in the order of steps and .

2. Insert the dry cells.

Into battery compartment, with their polarities
orientated as indicated ( , )in the

compartment.

3. Close the battery compartment lid.

Replace the battery compartment lid over the
compartment and slide until it clicks.

Effective range of remote
control operation

The remote control should normally be aimed at either
the front or rear remote control receiver window on the
projector (fig. 1). Otherwise, it may also be aimed at the
screen, which will reflect commands back to the
projector's front receiver window as illustrated in figure 2.

The effective control range is approx. 7 meters from
the beam receiver on the front or rear.

• Do not drop the remote control unit.

• Do not expose remote control unit to

any liquid.

• Do not use NiCd batteries.

Attention

• When the remote control is aimed at
the screen, the effective control range
may be reduced due to the optical loss
by screen reflection.

• The remote control may not function
properly if an object is in the light path.

• The remote control receiver may not
function properly in intense ambient
light such as fluorescent lamps.
Carefully site the projector so its
remote control receiver windows will
not be directly exposed to intense light.

Supplied AA dry cells
(insert the side first).

Every projector has its ID number and the ID number
of the controlling projector must be set to the remote
control in advance so that the user can operate the
remote control. The ID number of the projector is

set to “ALL” on shipping, and use the ID ALL
button of the remote control when using only a
single projector.

Procedure of ID setting

Press the ID SET button, and within five seconds, use
the NEXT button to set the number of the tens digit in
the ID number, which is already set in the projector,
and then use one of the numeric (0-9) buttons to set
the number of the units digit.
However, if the ID ALL button is pressed, the projector
can be controlled regardless of the ID number of the
projector (simultaneous control mode).

• If the ID SET button is pressed, the ID number goes
back to the one set before pressing the ID SET

Using the remote control unit

Setting projector ID number to remote control

button unless the NEXT button and a numeric button
are pressed within five seconds after the ID SET
button is pressed.

• Do not press the ID SET button accidentally or
carelessly because the ID number on the remote
control can be set even when no projector is around.

• Your specified ID number is stored in the remote
control unit unless another one is specified later.
However, the stored ID will be erased if the batteries
of the remote control are left exhausted. When the
dry cells are replaced, set the same ID number again.

Connection

Before connection, read carefully the instruction
manual for the device to be connected.

Turning off the power switch of the devices
before connecting cables.

If any connection cable is not supplied with the
device, or if no optional cable is available for
connection of the device, prepare a necessary
system connection cable to suit the device.

Video signals containing too much jitter may
cause the images on the screen to randomly
wobble or wafture. In this case, a time base
corrector (TBC) must be connected.

The projector accepts the following signals:
video, S-Video, analog RGB and digital signals
from the PC.

Some PC models cannot be connected to the
projector.

The pin-out and signal names of the S-VIDEO IN
terminal are shown in the diagram below.

The pin-out and signal names of the RGB2 input
terminal are shown in the diagram below.

• When the main power of the main unit is turned off, also turn off the power of the PC.

• When stacking projectors using RGB/YPBPR/YCBCR signals, divide the signals at the signal source

and use RGB1 input for both projectors. When the RGB1 OUT is connected to the external RGB
monitor, the image quality will be almost the same as that of checking monitors.

Note

Attention

• For the specifications of the RGB signals that can be applied from the PC, see the data sheet on
page 102.

• If your PC has the resume feature (last memory), the computer may not function properly until the
resume capability is disabled.

• The RGB 1 OUT (RGB 2) terminal will issue the signal that is connected to the input terminal of
RGB1.

When installing the projector, it is necessary to connect signals to the input module in accordance with the
connecting equipment.
Refer to the following diagram to establish proper signal connection.

• When switching multiple signals of the
same type and connecting to the same
input module (for example, when using
a signal chosen from multiple high­vision signals), use a signal selector for
this purpose and connect it with the
projector through RS-232C. Those
signals can be used individually
according to the input terminal on the
signal selector.

• Digital signals cannot be connected to
the signal selector.
