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 and case 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 use any type of abrasive pad, alkaline/acid cleaner, scouring powder, or 
volatile solvent, such as alcohol, benzene, thinner or insecticide. Using such 
materials or maitaining prolonged contact with rubber or vinyl materials may result 
in damage to the projector surface and cabinet material.
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 42 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 battery 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
Getting to know the 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) + 3/2 (hours used in normal mode)
See Setting Lamp Mode as Economic below for more information on Economic mode.
To obtain the lamp hour information:
1. Press Menu/Exit and then press  /  to highlight the SYSTEM SETUP: Advanced 
menu.
2. Press   to highlight Lamp Settings and press Mode/Enter. The Lamp Settings page 
displays.
3. You will see the Equivalent Lamp Hour information displaying on the menu.
4. To leave the menu, press Menu/Exit.
You can also get the lamp hour information on the INFORMATION menu.
Extending lamp life
The projection lamp is a consumable item that normally can last up to 2000-3000 hours 
with proper usage. To keep the lamp life as long as possible, you can do the following 
settings via the OSD menu.
Setting Lamp Mode as Economic
Using Economic mode reduces system noise and power consumption by 20%. If the 
Economic mode is selected, the light output will be reduced and result in darker 
projected pictures.
Setting the projector in Economic mode also extends the lamp operation life. To set 
Economic mode, go into the SYSTEM SETUP: Advanced > Lamp Settings > Lamp 
Mode menu and press  / .
Setting Auto Power Off
This function allows the projector to turn off automatically if no input signal is detected 
after a set period of time to prevent unnecessary waste of lamp life.
To  s e t  Auto Power Off, go into the SYSTEM SETUP: Basic > Auto Power Off menu and 
press  / . The time period can be set from 5 to 30 minutes in 5-minute increments. If 
the preset time lengths are not suitable for your presentation, select Disable. The 
projector will not automatically shut down in a certain time period.

Timing of replacing the lamp
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. Go to 
http://lamp.BenQ.com for a replacement lamp.
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 57 for details.
The following Lamp warning displays will remind you to change the lamp.
StatusMessage
The lamp has been in operation equivalent to 
2500 hours. Install a new lamp for optimal 
performance. If the projector is normally run with 
Economic selected (see Getting to know the lamp 
hour on page 52), you may continue to operate 
the projector until the 2950 hour lamp warning 
appears.
The lamp has been in operation equivalent to 
2950 hours. A new lamp should be fitted to avoid 
the inconvenience when the projector runs out of 
lamp time.
The lamp has been in operation equivalent to 
3000 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.
