Maintenance
Care of the projector
Your projector needs little maintenance. The only thing you need to do on a regular basis is 
to keep the lens clean.
Never remove any parts of the projector except the lamp. Contact your dealer if other parts 
need replacing.
Cleaning the lens
Clean the lens whenever you notice dirt or dust on the surface. 
• Use a canister of compressed air to remove dust. 
• If there is dirt or smears, use lens-cleaning paper or moisten a soft cloth with lens cleaner 
and gently wipe the lens surface.
Never rub the lens with abrasive materials.
Cleaning the projector case
Before you clean the case, turn the projector off using the proper shutdown procedure as 
described in Shutting down the projector on page 40 and unplug the power cord.
• To remove dirt or dust, wipe the case with a soft, lint-free cloth.
• To remove stubborn dirt or stains, moisten a soft cloth with water and a neutral pH 
detergent. Then wipe the case.
Never use wax, alcohol, benzene, thinner or other chemical detergents. These can damage the 
case.
Storing the projector
If you need to store the projector for an extended time, please follow the instructions below:
• Make sure the temperature and humidity of the storage area are within the 
recommended range for the projector. Please refer to Specifications on page 59 or 
consult your dealer about the range.
• Retract the adjuster feet.
• Remove the batteries from the remote control.
• Pack the projector in its original packing or equivalent.
Transporting the projector
It is recommended that you ship the projector with its original packing or equivalent.

Lamp information
Calculation of lamp hour
When the projector is in operation, the duration (in hours) of lamp usage is automatically 
calculated by the built-in timer. The method of calculating the equivalent lamp hour is as 
follows:
Total (equivalent) lamp hour
= 1 (hours used in Economic mode) + 4/3 (hours used in normal mode)
See Lamp mode (Normal) on page 49 for more information on Economic mode.
The lamp hour in Economic mode is calculated as 3/4 of that in normal mode. That is, using 
the projector in Economic mode helps to extend the lamp hour by 1/3.
Warning message
When the Lamp indicator lights up red or a message appears suggesting it is time to replace 
the lamp, please install a new lamp or consult your dealer. An old lamp may cause a 
malfunction in the projector and in some instances the lamp may explode.
The Lamp indicator light and Temperature warning light will light up if the lamp becomes too 
hot. Turn the power off and let the projector cool for 45 minutes. If the Lamp or Temp indicator 
still lights up after turning the power back on, please contact your dealer. See Indicators on 
page 56 for details.
The following Lamp warning displays will remind you to change the lamp.
MessageStatus
The lamp has been in operation for 3000 hours. 
Install a new lamp for optimal performance. If the 
projector is normally run with Economic Mode 
selected (See Lamp mode (Normal) on page 49), 
you may continue to operate the projector until the 
3950 hour lamp warning appears. 
The lamp has been in operation for 3950 hours. A 
new lamp should be fitted to avoid the 
inconvenience when the projector runs out of lamp 
time.

Replacing the lamp
• To reduce the risk of electrical shock, always turn the projector off and disconnect the 
power cord before changing the lamp.   
• 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 compromising 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.
• To assure optimal performance from the projector, it is recommended that you purchase a 
BenQ projector lamp for lamp replacement.
• If lamp replacement is performed while the projector is suspended upside-down from the 
ceiling, make sure that no one is underneath the lamp socket to avoid any possible injury 
or damage to the human eyes caused by fractured lamp.
1. Turn the power off and disconnect the projector from the wall socket. If the lamp is 
hot, avoid burns by waiting for approximately 45 minutes until the lamp has cooled. The lamp has been in operation for 4000 hours. 
It is strongly recommended that you replace the 
lamp at this age. The lamp is a consumable item. 
The lamp brightness diminishes with use. This is 
normal lamp behavior. You can replace the lamp 
whenever you notice that the brightness level has 
significantly diminished. If the lamp is not 
replaced beforehand, it must be replaced after 3000 
hours usage.
The lamp MUST be replaced before the projector 
will operate normally.

and scatter broken glass in the projector.
• Do not place the lamp in locations where water 
might splash on it, children can reach it, or near 
flammable materials.
• Do not insert your hands into the projector after 
the lamp is removed. If you touch the optical 
components inside, it could cause color 
unevenness and distortion of the projected 
images.
6. As shown in the figure, lower the new lamp 
first into the connector on the projector and 
align the two holes on the projector.
