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 
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 Shutting down the projector on page 43 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 61 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

you carry the projector yourself, please use the original box or provided soft carry case.

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.

Power Off menu and press  / . The time period can be set from 5 to 30 minutes in 5-
