Using the Projector’s Security Features
To prevent unauthorized use of the projector, you can do the 
following:
■Create an identifying user logo th at is displayed at startup and/or 
when the 
A/V Mute button is pressed
■Assign a password; this can be disabled for a set period if you want 
to loan the projector to someone
■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
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 of f or change it. This feature is 
intended to discourage theft and provides a way to identify the 
projector should it be stolen.  
						

							
66Fine-tuning the ProjectorIf you assign the projector a passwor
d, 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 passwo rd 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 “W here To Get Help” on page 95.
If someone else will be using the projector for awhile but you want to 
make sure that person returns it by  a certain time, you can temporarily 
disable the password for a set period. When that time has elapsed, the 
password is reactivated and must be  entered before the projector can 
be used.
When you enable the Operation Lock feature, all of the projector’s 
buttons are disabled except the  P
 Power button.
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 VCR. 
2. Press the 
Menu button and select the Extended menu.
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.
note
If the User’s Logo Protect 
function is 
ON, you see a 
message that th e 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 68.
