6. 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. See Cleaning the lens below for details.
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 57 and unplug the power cord.
• To remove dirt or dust, wipe the case with a soft, dry, 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 76 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
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:
Equivalent lamp hour 
= 1 (hours used in Economic mode) +4/3 (hours used 
in normal mode)
See Setting Lamp Power as Eco. below for more 
information on Eco. mode.
To obtain the lamp hour information:
1. Press MENU and then press  /  until the 
Advanced Setup menu is highlighted.
2. Press  to highlight Lamp and press ENTER. The 
Lamp page displays.
3. Highlight Lamp Hours and press ENTER to 
display the Lamp Hours information page.
4. To leave the menu, press MENU.
About Lamp Rest Rate:
Lamp Rest Rate shows the percentage of the lamp rest 
life. The method of calculating the rate is as follows:
Rest Rate = [1 - (Total Lamp Hours /4000)] x 100%
Extending lamp life
The projection lamp is a consumable item that normally 
can last up to 3000-4000 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 Power as Eco.
Using Eco. mode reduces system noise and power 
consumption by 20%. If the Eco. mode is selected, the 
light output will be reduced and result in darker 
projected pictures.
Setting the projector in Eco. mode also extends the lamp timer automatic shutdown feature. 
To  s e t  Eco. mode, go into the Advanced Setup > Lamp > Lamp Power menu and press  /
.
• Setting Auto Off
This function allows the projector to turn off automatically if no input source is detected 
after a set period of time.
To  s e t  Auto Off, go into the System Setup > Auto 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.
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 73 for details.
The following Lamp warning displays will remind you to change the lamp.
StatusMessage
The lamp has been in operation for 3000 hours. 
Install a new lamp for optimal performance. If the 
projector is normally run with Eco. selected (See
