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. Please be sure to turn off 
the projector and let it cool down completely before cleaning the lens.
•  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 
maintaining 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 Using the test pattern on page 38 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 60 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

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 Mode as Economic
Using Economic mode reduces system noise and power consumption by 30%. If the 
Economic 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 to 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 to the SYSTEM SETUP: Basic > Operation Settings > 
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.
