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.
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 50 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 77 
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
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 Economic mode) + 4/3 (hours used in normal mode)
See Setting Lamp Mode below for more information on Economic 
mode.
The lamp hour in Economic mode is calculated as 3/4 of that in Normal mode. 
That is, using the projector in Economic mode helps to extend the lamp hour by 1/
3.
To obtain the lamp hour information:
1. Press Menu/Exit and then press  /  until the SYSTEM SETUP: Advanced 
menu is selected.
2. Press   to select Lamp Settings and press Mode/Enter. The Lamp 
Settings page displays.
3. Select Lamp Information and press Mode/Enter.
4. You will see the Equivalent lamp hour information displaying on the menu.
5. To leave the menu, press Menu/Exit.
You can also get the lamp hour information on the INFORMATION menu.
Extending lamp life
The projection lamp is a consumable item. To keep the lamp life as long as possible, 
you can do the following settings via the OSD menu or remote control.
Setting Lamp Mode
Using Economic /SmartEco mode will reduces system noise and power 
consumption. If the Economic/SmartEco mode is selected, the light output will be 
reduced and result in darker projected pictures, the projector protected for longer 
working life.
Setting the projector in Economic/SmartEco mode also extends the lamp 
operation life. To set Economic/SmartEco mode, go into the SYSTEM SETUP: 
Advanced > Lamp Settings > Lamp Mode menu and press  / ..
The lamp modes are defined as the chart below.
Lamp ModeDescription
NormalProvides full lamp brightness
EconomicLowers brightness to extend the lamp life and decreases the

content brightness level 
						

							Maintenance 69
Setting Auto Power Off
This function allows the projector to turn off automatically if no input source is 
detected after a set period of time to prevent unnecessary waste of lamp life.
To  s e t  Auto Power Off, go into 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.

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. See Indicators on page 74 for details.
The following lamp warning displays will remind you to change the lamp.
The warning messages below are for reference only. Please follow the 
actual on-screen instructions to prepare and replace the lamp.
XXXX shown in the above messages are numbers that vary depending 
on different models.
StatusMessage
Install a new lamp for optimal performance. If 
the projector is normally run with Economic 
selected (Setting Lamp Mode on page 68), 
you may continue to operate the projector 
until the next lamp warning appears.
A new lamp should be fitted to avoid the 
inconvenience when the projector runs out of 
lamp time.
It is strongly recommended that you replace 
the lamp at this stage. The lamp is a 
consumable item. The lamp brightness 
diminishes with use. This is normal lamp 
behavior. You can replace the lamp whenever 
you notice that the brightness level has 
significantly diminished.
The lamp MUST be replaced before the 
projector will operate normally.
