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 52 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 a suitable soft carry case.
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 Dual-Reliable mode) + 3/2 (hours used in Dual-Brightest mode) + 3/2 (hours used in Single-
Alternative mode)
See "Setting the lamp mode" on page 39 below for more information.
To obtain the lamp hour information:
1. Press MENU/EXIT and then press / until the SYSTEM SETUP: Advanced menu is highlighted.
2. Press to highlight Lamp Settings and press ENTER. The Lamp Settings page displays.
3. You will see the Equivalent Lamp #1 Hour/Equivalent Lamp #2 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.
