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 Shutdown on page 26 and unplug the power cord.
• To remove dirt or dust, wipe the case with the supplied cleaning 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 45 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. When 
you carry the projector yourself, please use the original box or provided soft carry case.

Lamp information
Calculation of lamp hour
When the projector is in operation, the duration (by 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 = hours used in Economic mode + hours used in normal 
mode
See Economic Mode (off) on page 34 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 1/4.
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.
For more detailed information on projector warnings, please refer to Indicators on page 
41.
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.
The following Lamp warning displays will remind you to change the lamp.
MessageStatus
The lamp has been in operation for 2800 hours. 
Install a new lamp for optimal performance. If the 
projector is normally run with Economic Mode 
selected (See Economic Mode (off ) on page 34), 
you may continue to operate the projector until the 
2950 hour lamp warning appears.
The lamp has been in operation for 2950 hour. A 
new lamp should be fitted to avoid the 
inconvenience when the projector runs out of lamp 
time.
The lamp has been in operation for over 3000 hours. 
This message will flash in the center of the screen for 
about 30 seconds together with the Lamp indicator 
lighting up red for 40 seconds.
If this warning message displays, the projector will 
shutdown in 40 seconds. The lamp MUST be 
replaced before the projector will operate normally. 
						

							Maintenance 38
Replacing the lamp
• To reduce the risk of electrical shock, always turn the projector off and disconnect the 
power cord before changing the lamp.

Safety instructions for ceiling mounting of your BenQ
projector
We want you to have a pleasant experience using your BenQ projector, so we need to bring 
this safety matter to your attention to prevent damage to person and property.
If you intend to mount your projector on the ceiling, we strongly recommend that you use a 
proper fitting BenQ projector ceiling mount kit and that you ensure it is securely and safely 
installed.
If you use a non-BenQ brand projector ceiling mount kit, there is a safety risk that the 
projector may fall from the ceiling due to an improper attachment through the use of the 
wrong gauge or length screws.
You can purchase a BenQ projector ceiling mount kit from the place you purchased your 
BenQ projector. BenQ recommends that you also purchase a separate Kensington lock 
compatible security cable and attach it securely to both the Kensington lock slot on the 
projector and the base of the ceiling mount bracket. This will perform the secondary role of 
restraining the projector should its attachment to the mounting bracket become loose.
