OBSERVE ALL PRECAUTIONS
1.
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 alive, you will get a severe
shock. If you think the chassis is alive, 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 withstand voltage. Replacement parts must match these original specifications. Parts
whose specifications are particularly vital to safe use and maintenance of the set is marked
the circuit diagrams and parts list.
Substitution of these parts can be dangerous for you and the customer, so use only specified parts.
REMOUNT ALL PARTS AND RECONNECT ALL WIRES AS ORIGINALLY INSTALLED
4.
For safety, insulating tape and tubes are used throughout, but some lift-off parts on the printed
wiring board require special attention.

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.
LAMP
5.
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 deterioration as a result of servicing. In addition,
check insulation between external metallic parts and blades of walloutlet plugs. This examination is
indispensable in confirming complete establishment of safety.
(Insulation check)
Pull out a plug from a wall outlet to disconnect the connection cable. Then turn on the POWER
switch. Use a 500V megger (Note 2) and confirm that the insulation resistance is 1M
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 set.

2. Installation
Installation Requirements
• Do not use any other object than the projector’s sliding lens cover to cover the lens while the
projector is on.
• Doing so can cause the object to get extremely hot, and possibly resulting in a fire or damage due
to the heat emitted from the light output.
Place the projector in a horizontal position
The tilt angle of the projector should not exceed 10 degrees, nor should the projector be installed in any
way other than the desktop and ceiling mount, otherwise lamp life could decrease dramatically.
Fire and Shock Precautions
• Ensure that there is sufficient ventilation and that vents are unobstructed to prevent the build-up of
heat inside your projector. Allow at least 4 inches (10cm) of space between your 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 your projector. Do
not attempt to retrieve any objects that might fall into your projector. Do not insert any metal objects
such as a wire or screwdriver into your projector. If something should fall into your projector,
disconnect it immediately and have the object removed by a 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.
19
2. Installation
• The projector is designed to operate on a power supply of 100-240V AC 50/60 Hz. Ensure that
your power supply fits this requirement before attempting to use your 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 objects 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 other 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 a 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 you follow the instructions described in this
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 (only models with the RJ-45 LAN port):
For safety, do not connect to the connector for peripheral device wiring that might have excessive

become heated while the projector is turned on and immediately after the projector is turned
off.
• 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.
Remote Control Precautions
• Handle the remote control carefully.
• If the remote control gets wet, wipe it dry immediately.
• Avoid excessive heat and humidity.
• Do not short, heat, or take apart batteries.
• Do not throw batteries into fire.
• If you will not be using the remote control for a long time, remove the batteries.
• Ensure that you have the batteries’ polarity (+/−) aligned correctly.
• Do not use new and old batteries together, or use different types of batteries together.
• Dispose of used batteries according to your local regulations.
Note for US Residents
The lamp in this product contains mercury. Please dispose according to Local, State or Federal
Laws.
Lamp Replacement
• Use the specified lamp for safety and performance.
• To replace the lamp, follow all instructions provided on User’s Manual (
Replacing the Lamp
and the Filters (page 146)).
Be sure to replace the lamp and filter when the message [THE LAMP HAS REACHED THE END OF
•
ITS USABLE LIFE. PLEASE REPLACE THE LAMP AND FILTER.] appears. If you continue to use the
lamp after the lamp has reached the end of its usable life, the lamp bulb may shatter, and pieces of
glass may be scattered in the lamp case. Do not touch them as the pieces of glass may cause injury.
If this happens, contact your dealer for lamp replacement.
A Lamp Characteristic
The projector has a high-pressure mercury lamp as a light source.
A lamp has a characteristic that its brightness gradually decreases with age. Also repeatedly
turning the lamp on and off will increase the possibility of its lower brightness.
21
2. Installation
• 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.
About High Altitude mode
• Set [FAN MODE] to [HIGH ALTITUDE] when using the projector at altitudes approximately
5500 feet/1600 meters or higher.
Using the projector at altitudes approximately 5500 feet/1600 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 minutes and turn on the projector.
• Using the projector at altitudes less than approximately 5500 feet/1600 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/1600 meters or higher can shorten
the life of optical components such as the lamp.
