2. When you’re finished, press

Using the Projector’s Security Features
To prevent unauthorized use of the projector, you can do the 
following:
■Create an identifying user logo that is displayed at startup and/or 
when the 
A/V Mute button is pressed
■Assign a password
■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
■Install an anti-theft lock
If you create a user’s logo for the projector, you can lock the logo on so 
it is displayed as the startup screen and/or AV/Mute screen. 
Unauthorized users cannot turn it off or change it. This feature is 
intended to discourage theft and provides a way to identify the 
projector should it be stolen. 
If you assign the projector a password, a screen appears requesting the 
password whenever the projector is turned on. If you enter the 
password incorrectly three times in succession, the projector’s 
operation is locked and you’ll need to disconnect the power cord, then 
reconnect it to redisplay the password screen. If an incorrect password 
is entered 30 times in a row, the projector is locked and you’ll need to 
contact Epson to unlock it. See “Where To Get Help” on page 93.
When you enable the Operation Lock feature, all of the projector’s 
buttons are disabled except the P
 Power button.
note
If you should happen to 
enable the password before 
you set one and you see the 
prompt to enter the 
password, enter the default 
password 0000 to proceed. 
						

							Fine-tuning the Projector67
Creating Your Own Screen Logo
You can transfer any image on your computer to the projector, and 
then use it as the startup screen and/or the screen that is displayed 
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. The 
projector considers this image the “User’s Logo.” 
Follow these steps to capture the image and transfer it to the projector:
1. Display the image you want to use on the projector. You can use 
an image from either a computer or video source, such as a DVD 
player. 
2. Press the 
Menu button and select the Extended menu.
3. Use the down arrow button and press 
Enter to select User’s 
Logo
.
4. When you see a message asking if you want to use the present 
image as a user’s logo, select 
Yes and press Enter. A selection box 
displays over the image.
5. Use the arrow buttons on the projector or remote control to select 
the area of the image you want to use. Once you have selected the 
area, press 
Enter.
6. When you see the message 
Select this image?, choose Yes and 
press 
Enter. If you want to change the area selected, select No, 
press
 Enter and repeat steps 5 and 6. 
note
If the User’s Logo Protect 
function is 
ON, you see a 
message that the logo cannot 
be recorded. You’ll need to 
disable the User’s Logo 
Protect function before you 
can create or change the 
User’s Logo. See page 69. 
						

							68Fine-tuning the Projector7. When you see this screen, select a zoom rate (display size), and 
then press 
Enter.

not use the projector or other sources (computer, video, etc.) 
while the logo is being saved.

Completed, press Esc.

When the password function is enabled, you see this screen when you 
turn on the projector:
Use the numeric buttons on the remote control to enter the password. 
Once you have entered the password correctly, the password screen 
closes, and projection begins.

succession, you see the message 
The projector’s operation will be 
locked. Request code xxxxx
 and the projector switches to standby 
mode for approximately 5 minutes. Write down the request code. 
Then disconnect the projector’s power cord from the electrical outlet, 
reconnect it, and turn the projector back on. 
When you see the Password Protect Release screen again, you can try 
to enter the correct password.
If you have forgotten the password, contact Epson with the request 
code number that appears in the Password Protect Release screen for 
assistance. See “Where To Get Help” on page 93.
If you enter an incorrect password 30 times in succession, the 
projector remains locked and you must contact Epson to have the 
projector serviced.
