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.
CAUTION
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 31 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.
CAUTION
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 48 or

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 lamp hour = (hours used in Normal mode) + (hours used in Economic mode) + 
(hours used in Intelligent Eco mode)
To obtain the lamp hour information:
1. Press MENU on the projector or MENU/EXIT on the remote control and then press 
/  until the SYSTEM SETTING: ADVANCED menu is highlighted.
2. Press  to highlight Lamp Settings and press MODE/ENTER on the projector or 
remote control. The Lamp Settings page is displayed.
3. You will see the Equivalent lamp hour information on the menu.
4. To leave the menu, press MENU on the projector or MENU/EXIT on the remote 
control.
You can also get the lamp hour information on the INFORMATION menu.
Extending lamp life
The projection lamp is a consumable item. To keep the lamp life as long as possible, you 
can do the following settings via the OSD menu.
Setting Lamp Mode as Economic or Intelligent Eco
Using Economic/Intelligent Eco mode reduces system noise and power consumption. If 
the Economic/Intelligent Eco mode is selected, the light output will be reduced and result 
in darker projected pictures.
Setting the projector in Economic/Intelligent Eco mode also extends the lamp operation 
life. To set Intelligent Eco mode, go into the SYSTEM SETTING: ADVANCED > Lamp 
Settings > Lamp Mode menu and press  / .
Setting Auto Power Off
This function allows the projector to turn off automatically if no input source 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 SETTING: BASIC > Auto Power Off 
menu and press  / . 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.

WARNING
• The projector uses a high-pressure mercury glass lamp. 
• The lamp can break with a loud bang, or burn out, if jolted or scratched, handled while hot, 
or worn over time. Note that each lamp has a different lifetime, and some may burst or 
burn out soon after you start using them.
Hg - Lamp contains mercury. Manage in accordance with local disposal 
laws. See www.lamprecycle.org

when removing lamp glass that has shattered into sharp pieces. Before replacing the 
lamp, clean the lamp compartment and dispose of cleaning materials. Be careful of sharp 
edges in the lamp compartment. Wash hands after lamp replacement.
• If the lamp should break (it will make a loud bang when it does), ventilate the room well, 
and make sure not to inhale the gas or fine particles that come out from the projectors 
vent holes, and not to get them into your eyes or mouth.
• Only certified lamps are tested with this projector. Use of other lamps may cause electrical 
shock and fire.
• Be sure to place the projector on a flat surface to replace the lamp.
