Using the Projector Security Features
To prevent unauthorized use of the projector, you can do the 
following:
■Assign a password. You can use the password to prevent the 
projector from being turned on, prevent your custom startup 
screen from being changed, and lock network settings.
■Create a custom screen that is displayed at startup and/or when 
the 
A/V Mute button is pressed. The screen can be locked with a 
password to discourage theft and provides a way to identify the 
projector should it be stolen. See page 123. 
■Disable the projector’s buttons; this is useful, for example, if 
you’re projecting in a classroom and you want to ensure that no 
one touches the projector’s buttons while you’re using the remote 
control. See page 125. 
Enabling Password Protection
The default setting for the password is 0000. Follow these steps to 
create a new password:
1. Press the 
Freeze button on the remote control for about five 
seconds. You see this screen:
2. Use the  pointer button to select 
Password and press Enter.
3. When you see a message asking if you want to change the 
password, select 
Yes and press Enter.
note
You can also attach a 
security cable to the 
projector to prevent theft 
(see page 164).
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. Also, it’s a 
good idea to write down 
your password.  
						

							122Fine-Tuning the Projector4. Hold down the 
Num button on the remote control and use 
the numeric keypad to enter a four digit password. (The default 
setting is 0000.) 
5. When you see a confirmation message, reenter the password. 
Then press the 
Menu button to exit the screen.
To set security options, access the Password Protect screen as 
described on page 121, and then turn on any of the following options:
■Power On Protect to prevent unauthorized use of the projector. 
After the projector is plugged in and turned on, you must enter a 
password to use the projector. For details, see “Starting the 
Projector with a Password” below.
■User’s Logo Protect to prevent your custom screen and display 
settings from being changed. None of the User’s Logo features in 
the Extended menu can be changed when the User’s Logo Protect 
function is enabled. For details on creating a custom screen, see 
page 123.
■Network Protect to lock the Network settings in the menu 
system.
Starting the Projector with a Password
When the password function is enabled, you see this screen when you 
plug in and turn on the projector:
Hold down the 
Num button on the remote control and use the 
numeric keypad to enter the four digit password. The password screen 
closes and projection begins.
Hold down
note
If you leave the projector 
plugged in, the Password 
screen will not appear. It 
appears only if you unplug 
and reconnect the power 
cord.
Hold down 
						

							Fine-Tuning the Projector123
If the password is not correct, you see a message prompting you to 
re-enter the password. If you enter an incorrect password three times 
in succession, you see the message 
The projector’s operation will be 
locked. Request code xxxxx
. Write down the request code. The 
message displays for approximately 5 minutes, and then the projector 
switches to standby mode. Once the projector is in standby mode, 
disconnect the projector’s power cord from the electrical outlet, 
reconnect it, and turn the projector back on. 
When you see the Password screen again, you can try to enter the 
correct password.
If you enter an incorrect password 30 times in succession, the 
projector remains locked and you must contact Epson to unlock it. 
If you have forgotten the password, contact Epson with the request 
code number that appears in the Password screen for assistance. 
See “Where to Get Help” on page 161.
Creating Your Own Startup Screen
You can transfer any image from your computer or video source to the 
projector and then use it as your startup screen. You can also use it as 
the screen displayed when the projector is not receiving a signal or 
when you press the 
A/V Mute button. The image can be a company 
logo, slogan, photograph, or any other image you want to use. 
Capturing the Image
Start by displaying the image you want to use from either a computer 
or video source, such as a DVD player or digital camera. Then follow 
these steps to capture the image and transfer it to the projector: 
1. Press the 
Menu button, highlight the Extended menu, and press 
Enter.
note
When you choose an image 
for the user’s logo, it erases 
any previously used image. 
You can save an image up to 
400 × 300 pixels in size. 
Once you have saved a new 
user’s logo, you cannot 
return to the factory default 
logo. 
						

							124Fine-Tuning the Projector2. Highlight 
User’s Logo and press Enter.

buttons on the projector) to select the area of the image you want 
to use. Then press 
Enter.
5. When you see the message 
Select this image?, highlight Yes 
and press 
Enter. 
6. Highlight a zoom factor (display size) and press 
Enter.
7. When the message 
Save this image as the User’s Logo? 
appears, select 
Yes and press Enter. Saving the logo may take a 
few moments. Do not use your projector, remote control, or 
video source while the logo is being saved.
8. When you see the message 
Completed, press Menu to exit. 
Choosing When to Display the Image
After your image is saved, you can set it to display as the startup 
screen, the screen you see when there’s no signal, or the screen you see 
when you press the 
A/V Mute button (see page 67).
1. Press the 
Menu button, highlight the Extended menu, and press 
Enter.

automatically if it is idle and no signal is received for 1 to 30 
minutes (you can adjust the amount of time using the next 
setting).

							128Fine-Tuning the Projector
■Multi-screen
Use this option if you want to color-match two or more projectors 
that are being used to display images near each other, or you are 
using the multi-screen feature to project from one source (one 
image) with multiple projectors (see the EasyMP Network 
Projection Operation Guide). You can make image adjustments at 
each of five adjustment levels. First choose an 
Adjustment Level 
and then adjust the settings for each level: 
Brightness Correct to 
adjust the brightness, and 
Color Correct to adjust the balance 
between red and green, or blue and yellow. See the next section 
for more information about multi-screen color adjustment.
■Language 
Select a language to use for the projector menus and messages.
Multi-screen Color Adjustment
You can match the color of projected images when two or more 
projectors are being used to display images near each other, or when 
you use the multi-screen feature to project from one source (one 
image) as described in the EasyMP Network Projection Operation 
Guide. For each screen, you can set five levels of brightness and color 
correction.
1. Before starting, you may want to assign a numeric ID to each 
projector. This lets you use the remote control to select the 
projector you want to adjust. See page 71 for instructions.
To match the display colors as closely as possible, make sure that 
all the projectors are set to the same color mode before starting. 
See page 114 for instructions.
2. Press the 
Menu button, highlight the Extended menu, and press 
Enter. 
3. Select 
Multi-screen and press Enter.
4. Start by setting the 
Adjustment Level to 1 for two projectors. 
Then use 
Brightness Correct to match the darker projector to 
the lighter one. Press 
Enter to see the effects of your adjustments.
note
If you use two or more 
projectors side-by-side, 
exhaust from adjacent 
projectors might cause 
overheating. Leave at least 
2 feet (60 centimeters) of 
space between projectors. 
						

							Fine-Tuning the Projector129
5. Next, adjust the brightness of Level 5 for the same two projectors. 
Match the brighter projector to the darker one.
6. Adjust and match the brightness of Levels 2, 3, and 4. 
7. Adjust and match the G/R color correction for all levels. Then 
adjust and match the B/Y correction for all levels. 
8. If you are using three or more projectors, repeat steps 4 through 7 
to match projector 3 to projector 2, then match projector 4 to 
projector 3, and so on.
