Enabling Password Protection
To prevent unauthorized use of the projector, you can assign 
it a password. If you do, a screen appears requesting the 
password whenever the projector is plugged in and turned on. 
If an incorrect password is entered three times in succession, 
the projector’s operation is locked and the power cord must be 
disconnected and reinserted to redisplay the password screen. 
Note: If three attempts like this are made (an incorrect password 
is entered nine times in succession), the projector remains locked 
and you must contact the dealer to unlock it. Therefore, it’s a good 
idea to write your password down. Also, make a note of the 
“Request Code: xxxxx” number that appears in the Password 
Protect Release screen. If you do forget the password, you’ll need 
this code when you contact the dealer.
If you leave the projector plugged in (after turning if off), the 
projector does not ask for the password each time you turn it 
on. You need to enter the password only after unplugging and 
reconnecting the power cable.
The default setting for the password function is off. Follow 
these steps to turn password protection on:
1. Press the 
Freeze button on the remote control for about 
five seconds. You see this screen:
2. Use the   pointer button to set 
Security Lock to ON. 
Then press 
Enter.
Caution: If you lose the remote control, you will not be able to 
enter the password. Keep the remote control in a safe place at 
all times.
3. Select 
Password and press Enter.
4. When you see a message asking if you want to change the 
password, select 
Yes and press Enter.
5. Press the 
Num button on the remote control. When it 
lights, the numeric keypad is activated.
6. Use the numeric keypad to enter a four-digit password. 
(The default setting is 0000.) 
7. When you see a confirmation message, reenter the 
password. Then press the 
Menu button to exit the screen.
8. Press the 
Num button on the remote control to deactivate 
the numeric keypad.
Starting the Projector with a Password
When the password function is enabled, you see this screen 
when you plug in the projector:
1. Press the 
Num button on the remote control to activate the 
numeric keypad.
2. Enter the four digit password.
3. Press the 
Num button to deactivate the numeric keypad.
The Security Lock Release screen closes, and projection 
begins.
Shutting Down the Projector
When you’ve finished using the projector, follow the 
recommended procedure below to shut it down. This extends 
the life of the lamp and protects the projector from possible 
overheating. 
Note: When the projector has not received any input signals for 30 
minutes, it automatically turns off the projector lamp and enters 
sleep mode. This conserves electricity, cools the projector, and 
extends the life of the lamp. If you are done using the projector, 
unplug the power cord. If you want to start projecting again, press 
the P
Power button. 
You can turn off sleep mode using the 
Sleep Mode option in the 
Setting menu. If 
Standby Mode has been set to Network ON 
(in the Advanced1 menu), the lamp turns off but the projector 
does not go into full sleep mode. (It provides enough operation to 
allow network access.)
Follow these steps to turn off the projector:
1. Turn off any equipment plugged into the projector. 
2. To turn off the projector, press the red P
Power button on 
the projector or remote control. 
You see a confirmation 
message. (If you don’t want 
to turn it off, press any 
other button.)
3. Press the P
Power button again. The P power light flashes 
orange for about 40 seconds as the projector cools down. 
After the projector has cooled, the orange light stays on and 
the exhaust fan shuts off.

Managing Projectors from a Remote 
Computer
The EasyManagement software lets you monitor and control 
projector(s) from a remote computer. These features are 
intended for use by network administrators. 
❏Use EMP Monitor to see your projectors’ status, switch 
image sources, and control basic settings.
❏Use EMP NetworkManager to receive e-mail notifications 
alerting you to possible problems.
❏Use a network management utility running SNMP, such as 
HP OpenView,
™ to manage your facility’s equipment from 
a pre-existing system. 
Note: A plug-in is available to allow you to manage your 
projectors in HP OpenView. Additionally, other SNMP 
management utilities may be available in the future. Check with 
EPSON for availability.
Make sure you have installed the software (included on the 
projector’s CD-ROM) on the computer you want to use to 
monitor your projectors. (See the User’s Guide for 
instructions.)
Setting Up the Network
Connect each projector you want to monitor to your network 
and configure it with an appropriate IP address.
1. Connect the projector to your network using a 
commercially available 100baseTX or 10baseT network 
cable. Plug the cable into the projector’s Ethernet port.
2. Turn on the projector. 3. Press the 
Menu button on the remote control and select 
Network from the Advanced2 menu. 
4. If your network assigns addresses automatically, turn on 
DHCP.
5. If your network does not assign addresses automatically, 
turn off 
DHCP and enter the projector’s IP Address, 
Subnet Mask, and Gateway Address, as needed. 
❏To enter numbers using the remote control, press the

Cleaning the Lens 
Clean the lens whenever you notice dirt or dust on the surface. 
❏Use a canister of compressed air to remove dust. 
❏To remove dirt or smears on the lens, use lens-cleaning 
paper. If necessary, moisten a soft cloth with lens cleaner 
and gently wipe the lens surface.
Caution: Do not use glass cleaner to clean the lens.
Cleaning the Projector 
Before you clean the case, first turn off the projector and 
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 mild detergent. Then wipe the case. 
❏Do not use wax, alcohol, benzene, paint thinner, or other 
chemical detergents. These can damage the case.
Cleaning the Air Filters and Vents
Clean the air filters and air intake vents after every 100 hours 
of use. If they are not cleaned periodically, they can become 
clogged with dust, preventing proper ventilation. This can 
cause overheating and damage the projector. 
Follow these steps:
1. Turn off the projector and unplug the power cord.
2. To clean the intake vents, EPSON recommends using a 
small vacuum cleaner designed for computers and other 
office equipment. If you don’t have one, gently clean the 
vents with a soft brush (such as an artist’s paintbrush).3. Gently turn the projector over and remove the filters from 
the side and bottom of the projector. Then use a small 
vacuum cleaner or soft brush to clean the two filters. Slide 
the filters back into place when you’re done.
4. If the dirt is difficult to remove or a filter is broken, replace 
the filters as described below. Contact your dealer or call 
EPSON at (800) 873-7766 in the United States to obtain 
new ones. In Canada, please call (800) 463-7766 for dealer 
referral.
Replacing the Lamp and Air Filters
The life span of the projection lamp is about 2000 hours. It is 
time to replace the lamp when: 
❏The projected image gets darker or starts to deteriorate.
❏The message 
LAMP REPLACE appears on the screen when 
the lamp comes on (after about 1900 hours) and the 
lamp warning light is flashing orange. To maintain 
projector brightness and image quality, replace the lamp as 
soon as possible. 
❏The   lamp warning light is flashing red (the lamp is 
burnt out).
Contact your dealer or call EPSON at (800) 873-7766 in the 
United States for a replacement lamp. Request part number 
V13H010L22. In Canada, please call (800) 463-7766 for 
dealer referral.
Note: When you get a replacement lamp for your projector, new 
air filters are included. You should replace the filters when you 
replace the lamp. You can check how long the lamp has been in 
use (see page 20).
Wa r n i n g :  Let the lamp cool fully before replacing it. In the 
unlikely event that the lamp has broken, small glass fragments 
may be present and should be removed carefully to avoid injury.
