Important Safety Notices

• RISK OF ELECTRIC SHOCK DO NOT OPEN

• TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE COVER. NO USER­SERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED SERVICE PERSONNEL.

This symbol warns the user that uninsulated voltage within the unit may have sufficient
magnitude to cause electric shock. Therefore, it is dangerous to make any kind of
contact with any part inside of this unit.

This symbol alerts the user that important literature concerning the operation and
maintenance of this unit has been included.

Therefore, it should be read carefully in order to avoid any problems.

• HEAT SINK MAY BE ENERGIZED. TEST BEFORE TOUCHING.

• The heat sink located on the power board is electrified. A mark is attached to the primary heat
sink. Pay attention to this area.

During servicing carefully observe the following.

1. OBSERVE ALL PRECAUTIONS

Items and locations that require special care during servicing, such as the cabinet, chassis, and
parts are labelled with individual safety instructions. Carefully comply with these instructions and all
precautions in the instruction manual.

2. BE CAREFUL OF ELECTRIC SHOCK

The chassis carries an AC voltage. If you touch the chassis while it is still live, you will get a severe
shock. If you think the chassis is live, use an isolating transformer or gloves, or pull out the plug
before replacing any parts.

3. USE SPECIFIED PARTS

The components have been chosen for minimum flammability and for specific levels of resistance
value and ability to withstand voltage. Replacement parts must match these original specifications.
Parts whose specifications are particularly vital to safe use and maintenance of the set are marked

on the circuit diagrams and parts list.

Substitution of these parts can be dangerous for you and the customer, so use only specified parts.

4. REMOUNT ALL PARTS AND RECONNECT ALL WIRES AS ORIGINALLY INSTALLED

For safety, insulating tape and tubes are used throughout, but some lift-off parts on the printed
wiring board require special attention.

1

All wires are positioned away from high-temperature and high-voltage parts, and, if removed for
servicing, they must be retuned precisely to their original positions.

5. LAMP

Be very careful of the lamp because it generates high heat while it is used at high voltage. When
replacing the bulb, make sure it is cool enough.

6. LENS

Do not look into the lens during projection. This is important to avoid damage to the eyes.

7. SERVICING

At the time of repair or inspection services, use an earth band (wrist band), without fail.

8. RUN A COMPLETE SAFETY CHECK AT THE COMPLETION OF SERVICING

After completion of servicing, confirm that all screws, parts, and wiring, removed or disconnected
for servicing, have been returned to their original positions. Also examine if the serviced sections
and peripheral areas have suffered from any damage as a result of servicing. In addition, check
the insulation between external metallic parts and the blades of wall outlet plugs. This examination
is indispensable in confirming complete establishment of safety.

Insulation check:

Pull out the plug from the wall outlet to disconnect the connection cable. Then turn on the POWER
switch. Use a 500V ohmmeter (Note 2) and make sure that the insulation resistance is 1M or
more between each terminal of the plug and exposed external metal (Note 1). If the measured
value is below the specified level, then it is necessary to inspect and fix the machine.

Note 1: Exposed external metal....RGB input terminals, control terminals, etc.

Note 2: If a 500V ohmmeter is not available for an unavoidable reason, then use a circuit tester or
the like for inspection.

2. Installation

Installation Requirements

• Do not cover the lens with the lens cap or equivalent while the projector is on. Doing so can lead to
melting of the cap due to the heat emitted from the light output.

• Do not place any objects which are easily affected by heat in front of the projector lens. Doing so
could lead to the object melting from the heat that is emitted from the light output.

Do not use the projector with it leaning to the left or right. This may result in a malfunction. However,
portrait installation is possible* (when a custom-designed stand is made). For portrait installation, install
the projector with the intake vent at the bottom and leave a space of at least 130 mm below the intake
vent.

Fire and Shock Precautions

• Ensure that there is sufficient ventilation and that vents are unobstructed to prevent the build-up of
heat inside the projector. Allow at least 4 inches (10cm) of space between the projector and a
wall.

• Do not try to touch the ventilation outlet on the left front (when seen from the front) as it can become
heated while the projector is turned on and immediately after the projector is turned off. Parts of the
projector may become temporarily heated if the projector is turned off with the Power button or if
the AC power supply is disconnected during normal projector operation.

Use caution when picking up the projector.

• Prevent foreign objects such as paper clips and bits of paper from falling into the projector. Do not
attempt to retrieve any objects that might fall into the projector. Do not insert any metal objects such
as a wire or screwdriver into the projector. If something should fall into the projector, disconnect it
immediately and have the object removed by qualified service personnel.

• Do not place any objects on top of the projector.

• Do not touch the power plug during a thunderstorm. Doing so can cause electrical shock or fire.

23

2. Installation

• The projector is designed to operate on a power supply of 100-240V AC 50/60 Hz. Ensure that
the power supply fits this requirement before attempting to use the projector.

• Do not look into the lens while the projector is on. Serious damage to your eyes could result.

• Keep any items (magnifying glass etc.) out of the light path of the projector. The light path being
projected from the lens is extensive, therefore any kind of abnormal object that can redirect light
coming out of the lens, can cause an unpredictable outcome such as a fire or injury to the eyes.

• Do not place any objects which are easily affected by heat in front of a projector exhaust vent.

Doing so could lead to the object melting or getting your hands burned from the heat that is emitted
from the exhaust.

• Handle the power cord carefully. A damaged or frayed power cord can cause electric shock or
fire.

• Do not use any power cord other than the one supplied with the projector.

• Do not bend or tug the power cord excessively.

• Do not place the power cord under the projector or any heavy object.

• Do not cover the power cord with soft materials such as rugs.

• Do not heat the power cord.

• Do not handle the power plug with wet hands.

• Turn off the projector, unplug the power cord and have the projector serviced by qualified service
personnel under the following conditions:

• When the power cord or plug is damaged or frayed.

• If liquid has been spilled into the projector, or if it has been exposed to rain or water.

• If the projector does not operate normally when following the instructions described in the
user’s manual.

• If the projector has been dropped or the cabinet has been damaged.

• If the projector exhibits a distinct change in performance, indicating a need for service.

• Disconnect the power cord and any other cables before carrying the projector.

• Turn off the projector and unplug the power cord before cleaning the cabinet or replacing the
lamp.

• Turn off the projector and unplug the power cord if the projector is not to be used for an extended
period of time.

• When using a LAN cable:

For safety, do not connect to a connector for peripheral device wiring that might have excessive
voltage.

24

• Do not use the tilt-foot for purposes other than originally intended. Misuses such as gripping the tilt­foot or hanging on the wall can cause damage to the projector.

Installation Requirements

• Do not send the projector in the soft case by parcel delivery service or cargo shipment. The
projector inside the soft case could be damaged.

• Select [HIGH] in Fan mode if continuing to use the projector for consecutive days. (From the menu,
select [SETUP] [INSTALLATION] [FAN MODE] [HIGH].)

• Before using Direct Power Off, be sure to allow at least 20 minutes immediately after turning on the
projector and starting to display an image.

• Do not unplug the power cable from the wall outlet or projector when the projector is powered on.
Doing so can cause damage to the AC IN connector of the projector and (or) the prong plug of the
power cable.
To turn off the AC power supply when the projector is powered on, use a power strip equipped
with a switch and a breaker.

• Do not turn off the AC power for 60 seconds after the lamp is turned on and while the Power
indicator is blinking blue. Doing so could cause premature lamp failure.

Caution on Handling the Optional Lens

When shipping the projector with the lens, remove the lens before shipping the projector. Always attach
the dust cap to the lens whenever it is not mounted on the projector. The lens and the lens shift
mechanism may encounter damage caused by improper handling during transportation.

Do not hold the lens part when carrying the projector.

Doing so could cause the focus ring to rotate, resulting in accidental dropping of the projector.

Lamp Replacement

• Use the specified lamp for safety and performance.

• For US Residents

• LAMP(S) INSIDE THIS PRODUCT CONTAIN MERCURY AND MUST BE RECYCLED OR
DISPOSED OF ACCORDING TO LOCAL, STATE OR FEDERAL LAWS.

• DO NOT TOUCH THE LAMP immediately after it has been used. It will be extremely hot. Turn the
projector off and then disconnect the power cord. Allow at least one hour for the lamp to cool
before handling.

• When removing the lamp from a ceiling-mounted projector, make sure that no one is under the
projector. Glass fragments could fall if the lamp has been burned out.

This product contains substances which are harmful to humans and the environment.

• The lamp contains mercury.

25

2. Installation

Please dispose of this product or used lamps in accordance with local regulations.

• Notes for Residents

The lamp is this product contains mercury. Please dispose according to Local, State or Federal
laws.

Mercury bridge

This projector uses a high-pressure mercury lamp as a light source. Mercury is used inside, which is
in a liquid state at normal temperature, and in a gasified state when the lamp is lit.

The gasified mercury returns to a liquid state when the lamp is turned off. At that time, there are very
rare cases where the liquefied mercury adheres between the electrodes, which may cause a short­circuit between the electrodes. This phenomenon is called a “mercury bridge”. (See the diagram
below)

In such a case, the lamp cannot be lit. Generally, this problem tends to occur when the power is
forcibly turned off (Example: Disconnecting the AC cable while the power is on, power outage
occurring, breaker being thrown).

About High Altitude Mode

• Set [FAN MODE] to [HIGH ALTITUDE] when using the projector at altitudes approximately 5500
feet/1700 meters or higher.

Using the projector at altitudes approximately 5500 feet/1700 meters or higher without setting to
[HIGH ALTITUDE] can cause the projector to overheat and the protector could shut down. If this
happens, wait a couple of minutes and turn on the projector.

• Using the projector at altitudes less than approximately 5500 feet/1700 meters and setting to
[HIGH ALTITUDE] can cause the lamp to overcool, causing the image to flicker. Switch [FAN
MODE] to [AUTO].

• Using the projector at altitudes approximately 5500 feet/1700 meters or higher can shorten the
life of optical components such as the lamp.

Handling of margin in shadow adjustment

During shadow adjustment, adjust the margin so that it is balanced vertically and horizontally. If
adjustments are carried out from the LCD panel, this margin cannot be seen directly. Therefore, try to
move the shadow until its top, bottom, right, or left part appears. By doing so, examine how much
shadow is existing vertically and horizontally. Stop moving the shadow where its margin seems to be
well balanced.
