lens during operation. The intense
light beam may damage your eyes.

• In some countries, the line voltage is
NOT stable. This projector is designed
to operate safely within a bandwidth
of 100 to 240 volts, but could fail if

power cuts or surges of ±10 volts

occur. In these high-risk areas, it is
recommended to install a power
stabilizer unit.

Important Safety Instructions 1

Safety Instructions

1. The lamp becomes extremely hot dur­ing operation. Allow the projector to
cool for approximately 45 minutes
prior to removing the lamp assembly
for replacement.

2. Do not operate lamps beyond the
rated lamp life. Excessive operation of
lamps beyond the rated life could
cause them to explode on rare occa­sions.

4. Do not place this product on an
unstable cart, stand, or table. The
product may fall, sustaining serious
damage.

5. To reduce the risk of electric shock, do
not disassemble this appliance.

*Take it to a qualified technician when
service or repair is required. Incorrect
reassembly can cause electric shock when
the appliance is subsequently used.

3. Never replace lamp assembly or any
electronic components unless the pro­jector is unplugged.

Important Safety Instructions2

6. This product is capable of displaying
inverted images for ceiling mount
installation. Please use BenQ’s Ceiling
Mounting Kit for mounting the unit

Safety Instructions (Continued)

7. Do not block the ventilation holes.

- Do not place this unit on a blanket or
other bedding.

- Do not cover this unit with a cloth.

- Do not place any inflammables near the
ventilation holes.

9. Always place the unit on a level, hori­zontal surface during operation.

- Do not use if tilted at an angle of more
than 10 degrees left to right, nor at angle
of more than 15 degrees front to back.
Using the unit when it is not fully
horizontal may cause a malfunction of, or
damage to, the lamp.

If the ventilation holes are seriously
obstructed, overheating inside the unit
may result in a fire.

8. Do not place this unit in any of the fol­lowing environments.

- Space where is poorly ventilated or
confined. Allow at least 50 cm clearance
from walls.

- Locations where temperatures may
become excessively high, such as the inside
of a car with all windows rolled up.

- Locations where excessive humidity, dust,
or cigarette smoke may contaminate
optical components, shortening the
projector’s lifespan and darkening the
screen.

- Locations near fire alarms

10. Do not stand the unit on end vertically.

Doing so may cause the unit to fall over,
causing injury or resulting in damage to
the unit.

11. Do not step on this unit or place any
objects upon it.

Besides probable physical damage to the
unit, doing so may result in accidents and
possible injury.

The lamp has been in operation for 1900 hours. Change a
new lamp for optimal performance.

The lamp has been in operation for 1980 hours, and the
power will turn off after 20 hours.

The lamp has been in operation for over 2000 hours. The
warning message will display for 30 seconds every 5 minutes
after you turn on the projector and the power will turn off
automatically in 10 minutes.

LED blinks rapidly.

When the projector’s internal temperature is too high to
operate safely, the LED blinks slowly for one minute and the
lamp turns off automatically.

If the LED light is off, the projector’s lamp and temperature

The LAMP indicator will light up if the lamp becomes too hot. Turn off the power and let the

projector cool for 45 minutes. If the LAMP indicator is still red when turning the power on,
please contact your dealer.

Maintenance 21

Lamp Replacement

To reduce the risk of electrical shock, always turn off the projector and disconnect the power
cord before changing the lamp.

1. Press the POWER button to switch off the projector. Disconnect the power cord
from the outlet and the projector.

2. Loosen the screw and remove the
lamp cover. If the lamp is hot, avoid
burns by waiting 45 minutes until
the lamp has cooled.

3. Loosen the 3 screws. (It is strongly
recommended you use a magnetic­headed screwdriver.) Pull the handle
to remove the lamp housing. If the
screws are not loosened completely,
they could injure your fingers. Do
not insert your hand into the box
after the lamp is removed. If you
touch the optical parts inside, this
could cause color unevenness.

4. Replace the lamp with a new one.
Insert it into the projector, and
tighten the screws firmly. Loose
screws may cause a bad connection,
which may result in malfunction.

5. Re-install the lamp cover and tighten
the screw. Do not turn on the power
with the lamp cover removed.
Whenever the lamp is replaced, reset
the total lamp operation time. Do
not reset if the lamp is not replaced
as this could cause breakage.

To reduce the risk of severe burns, allow

the projector to cool for at least 45 minutes
before replacing the lamp.

To reduce the risk of injuries to fingers and
damage to internal components, use cau­tion when removing lamp glass that has
shattered into sharp pieces.

To reduce the risk of injuries to fingers
and/or decreasing image quality by touch­ing the lens, do not touch the empty lamp
compartment when the lamp is removed.

This lamp contains mercury. Consult your
local hazardous waste regulations to dis­pose of this lamp in a proper manner.
