							Using Projector Setups
You can store projector setup parameters for up to six sources (three
for computer image sources and three for video image sources) for
instant recall when you need them. These setups remain in memory
even when you turn off the projector. The settings available for you to
save depend on the currently selected image source, as described below.
When the projector is using the computer as its image source, you can
change and save these settings:•Comp sync (control panel setting)
lComp tracking (control panel setting)
lBrightness (main menu setting)
•Contrast (main menu setting)
lHorizontal position (main menu setting)
•Vertical position (main menu setting).
When the projector is using a video image source, you can change and
save these settings:
lBrightness (main menu setting)
•Contrast (main menu setting)
•Color (main menu setting)
lTint (main menu setting, NTSC only).

							Storing a setup
Important! Saving new settings in a memory area automatically replacesany settings previously stored in that memory area.
1.Use the Preset button on the control panel to choose the memory
area where you want to store your projector settings. The status
light indicates the currently selected memory area (1, 2, or 3).
Pressing the Preset button changes the selected memory area (or
turns off the projector setup feature) in this sequence:
2.While the status light for the memory area you want is lit, check
the projected image and make your projector settings. You can
adjust the following settings:
•Sync, tracking, brightness, contrast, and vertical and
horizontal position for a computer image
•Brightness, contrast, color, and tint (NTSC only) for a video
image.
See “Using the control panel” on page 26 in Chapter 2 and “Using
the Main Menus” on page 30 for instructions on changing
projector settings.
3.After you select your projector settings, hold down the Preset
button for about three seconds, until the memory area status light
starts flashing. Then release the Preset button; the status light
stops flashing and stays on, and the projector setup is stored in the
selected memory area.

							Recalling a setup
Important! Recalling a setup replaces your current projector settings with
the settings that were saved in memory.
Use the Preset button on the control panel to select the memory area
that contains the settings you want to recall.

When you don’t want a preset projector setup anymore, you can clear
its memory area. This removes your settings from the memory area and
replaces them with the projector’s default settings. To clear a preset
setup, follow these steps:1.Use the Preset button on the control panel to choose the memory
area you want to clear.
2.Hold down the Preset button for approximately 15 seconds. The
status light alternates between flashing and staying lit; when it
remains lit, release the Preset button.

							MaintenanceTheprojector needs little maintenance. You should keep the lens
clean, because any dirt or smears appear on the screen. You also need
to periodically clean the air filter at the bottom of the projector.
Cleaning the air filter is important, because a clogged air filter can
block ventilation needed to cool the projector and keep it from
overheating. Before you clean any part of the projector, always turn off
the projector and unplug the power cord.
The only parts you should replace are the lamp and air filter. If any
other part needs replacing, contact your ELP-3500 dealer or a
qualified service person.

							Warning: Never open any cover on the projector, except the lamp and
filter covers. Dangerous electrical voltages in the projector can injure you
severely. Do not try to service this product yourself except as specifically
explained in this Owners Manual. Refer all servicing to qualified service
personnel.
Cleaning the Lens
Clean the lens whenever you notice dirt or dust on the surface. Lightly
wipe the lens surface with a soft, dry, lint-free cloth. To remove dirt or
smears on the lens, moisten a soft cloth with an alcohol-based cleaner
and gently wipe the lens surface.
Cleaning the Projector Case
To clean the projector case, first 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
detergent. Then wipe the case. Do not use alcohol, benzene, thinner,
or other chemical detergents. These can cause the case to warp.424 l Maintenance 
						

							Cleaning the Air Filter
Clean the air filter at the bottom of the projector after every 100 hours
of use. If it is not cleaned periodically, it can become clogged with
dust, preventing the projector from being ventilated properly. This can
cause overheating and damage the projector. To clean the air filter,
follow these steps:1.Turn off the projector and unplug the power cable from the wall
outlet.
2.Turn the projector so that its handle is on top so you can access
the filter easily.
Caution: Stand the projector with the handle at the top to keep dust from
getting inside it.
3.Use a flat-head screwdriver to lift and remove the filter cover.
Cleaning the Air Filter43 
						

							4.The filter is attached to the other side of the filter cover. It is
recommended that you use a small vacuum cleaner designed for
computers and other office equipment to clean the filter. If you
don’t have one, use a dry, lint-free cloth.
If the dirt is difficult to remove or if the filter is torn, replace it.
Contact your ELP dealer or call EPSON Accessories
(800-873-7766 in the United States) to obtain a new one. Be sure
to request part number 1023658.
5. Replace the filter.
6.Reconnect the power cord to the wall outlet.
Replacing the Lamp
The projector lamp typically lasts for about 4000 hours of use. It is
time to replace the lamp when:
lYou notice that projected images get darker or start to deteriorate.
lThe lamp warning light is red.
Contact your local EPSON dealer or call EPSON Accessories
(800-873-7766 in the United States) for a replacement lamp. Use only
replacement lamp part number ELPLP02.
Warning: Let the lamp cool before replacing it. During use, it becomes hotenough to burn you.

wall outlet.
