High Altitude Mode
The mode is for operation in areas like high altitude or high temperature 
environments. Activate the function when your environment is between 1500 m 
–3000 m above sea level and ambient temperature is between 0°C–30°C.
Do not use this function if your altitude is between 0 m and 1500 m and 
ambient temperature is between 0°C and 35°C. If you turn on the mode 
under such a condition, the projector will be over cooled.
Operation under High Altitude Mode may cause a higher decibel operating 
noise level because of increased fan speed necessary to improve overall system 
cooling and performance.
If you use this projector under other extreme conditions excluding the above, it 
may display auto shut-down symptoms, which is designed to protect your 
projector from over-heating. In cases like this, you should switch to High 
Altitude Mode to solve these symptoms. However, this is not to state that 
this projector can operate under any and all harsh or extreme conditions.
Password
For security purposes and to prevent unauthorized use, you may set up 
password security for the projector. See Utilizing the password function for 
details. 
• Change Password
You will be asked to enter the current password before changing to a new one.

Maintenance
Care of the projector
Your projector needs little maintenance. The only thing you have to do on a regular basis is keep the lens 
clean. 
Never remove any parts of the projector except the lamp. Contact your dealer or local customer service 
center if the projector fails to operate as expected.
Cleaning the lens
Clean the lens whenever you notice dirt or dust on the surface. 
Before cleaning any part of the projector, turn it off using the proper shutdown procedure (see Shutting 
down the projector), unplug the power cable, and let it cool down completely. 
•  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.
Never touch the lens with your finger or rub the lens with abrasive materials. Even paper towels can damage 
the lens coating. Only ever use a proper photographic lens brush, cloth, and cleaning solution. Do not 
attempt to clean the lens while the projector is switched on or is still hot from previous use.
Cleaning the projector case
Before cleaning any part of the projector, turn it off using the proper shutdown procedure (see Shutting 
down the projector), unplug the power cable, and let it cool down completely. 
•  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 detergent. Then 
wipe the case.
Never use wax, alcohol, benzene, thinner or other chemical detergents. These can damage the case.
Storing the projector
To store the projector for an extended time:
•  Make sure the temperature and humidity of the storage area are within the recommended range for 
the projector. Refer to Specifications 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.

replacement lamp.
The LAMP indicator light and TEMP 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 for details.
Please replace the lamp when the following lamp warning messages appear.
The illustrations show the examples of messages you will see under the Basic menu. They are for reference 
only and may differ from the actual design and the menu type you’ve selected.
The XXXX shown in the above messages are numbers that vary depending on different models.

							50 Maintenance  
Replacing the lamp
•  To reduce the risk of electrical shock, always turn the projector off and disconnect the power cable 
before changing the lamp.
•  To reduce the risk of severe burns, allow the projector to cool for at least 45 minutes before replacing the 
lamp.
•  To reduce the risk of injuries to fingers and damage to internal components, use caution when removing 
lamp glass that has shattered into sharp pieces.
•  To reduce the risk of injuries to fingers and/or compromising image quality by touching the lens, do not 
touch the empty lamp compartment when the lamp is removed.
•  This lamp contains mercury. Consult your local hazardous waste regulations to dispose of this lamp in a 
proper manner.
•  To assure optimal performance from the projector, it is recommended that you purchase a qualified 
projector lamp for lamp replacement.
•  If lamp replacement is performed while the projector is suspended upside-down from the ceiling, make 
sure that no one is underneath the lamp socket to avoid any possible injury or damage to the human eyes 
caused by fractured lamp.
•  Ensure good ventilation when handling broken lamps. We recommend that you use respirators, safety 
glasses, goggles or face shield and wear protective clothing such as gloves. 
1. Turn the power off and disconnect the projector from the power outlet. If the lamp is hot, avoid 
burns by waiting for approximately 45 minutes until the lamp has cooled.
2. Loosen the screws that secure the lamp cover on the top 
of the projector until the lamp cover loosens.
3. Remove the lamp cover from the projector.
4. Confirm a position of the lamp protection film to put a 
new film on the same position later, then remove and 
dispose of the lamp protection film.
•  Do not turn the power on with the lamp cover removed.
•  Do not insert your fingers between the lamp and the 
projector as the sharp edges inside the projector may cause 
injuries.
5. Disconnect the lamp connector from the projector as 
illustrated.
6. Loosen the screw that secures the lamp.
7. Lift the handle so that it stands up.
