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.” 
Capturing the Image
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 
or digital camera. 
2. Press the 
Menu button and select the User’s Logo menu.
3. 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.
4. Use the directional buttons to select the area of the image you 
want to use. Once you have selected the area, press 
Enter.
5. 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 4 through 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 59.

6. Use the directional buttons on the remote control to select a zoom 
rate (display size), and then press 
Enter. 
7. When you see the message “Save image as user’s logo?,” select 
Yes 
and press 
Enter. Saving the logo takes few moments. Do not use 
the projector or other sources (computer, video, etc.) while the 
logo is being saved.
8. When you see the message “Completed,” press 
Esc or Menu.
Choosing When to Display the Screen Logo
After your screen logo is saved, you can set it up as the startup screen 
and/or the background screen, which is displayed when you press the 
A/V Mute button.
1. Press the 
Menu button to open the menu (if it is not already 
open).
2. To display the logo as the background screen when the 
A/V Mute 
button is pressed, select the Setting menu and press 
Enter. Select

Advanced 
menu and press Enter. Select Startup Screen, highlight ON, and 
press 
Enter. 
4. When you’re finished, press
 Esc or Menu.

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 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 
nine 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 83.
If you have created a user’s logo for the projector (as described on 
page 56), you can also 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. 
Additionally, if someone else will be using the projector for a while 
but you want to make sure that person returns it by a certain time, you 
can temporarily disable the password for set period. When that time 
has elapsed, the password is reactivated and must be entered before the 
projector can be used.
Follow the instructions below to first set the password, and then turn 
on the password and/or user logo protection. Be sure to set the 
password before you turn it on; otherwise, you may lock yourself out 
of the projector. 
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.

Setting a Password 
1. Press the Freeze button on the remote control for about 7 
seconds, until you see the Password Protect menu:
2. Select 
Password and press Enter. You see the message Change 
the password?
 
3. Select 
Yes and press Enter.
4. Enter a 4-digit password using the numeric keypad on the remote 
control. 
The password will be displayed as 
****. After you enter the last 
digit, a confirmation screen appears. Enter the password again.
5. After you finish setting the password, press the 
Esc button to 
return to the Password Protect menu.
Make a note of the password and keep it in a safe place in case you 
forget it. 
Turning On the Password and User’s Logo
1. To enable the password, select Power ON Protect and press 
Enter. Select ON then press Esc. 
2. If you want to disable the password temporarily, select 
Timer and 
press 
Enter. Then use the numeric keypad to enter the number of 
hours (from 0 to 999) that you want the password feature 
disabled. If you want the projector to request the password every 
time it is turned on, set the timer to 
0H. 
The countdown for the elapsed time begins as soon as you close 
the Password Protect menu. (You can check the elapsed time in 
this menu next to 
Time elapsed.)
note
If a password has already 
been set, you see the 
Password Protect Release 
screen. See “Starting the 
Projector with a Password” 
on page 60.
Use these buttons like a 
numeric keypad to enter 
the password 
						

							60Fine-tuning the Projector3. To enable your screen logo, select 
User’s Logo Protect and press 
Enter. Select ON and press Enter. 
When this feature is on the logo appears whenever the projector is 
turned on (if the Startup Screen is enabled) and as the A/V Mute 
screen (if you enabled the logo for the 
Background Color 
setting). None of the User’s Logo features can be changed when 
the User’s Logo Protect function is enabled.
4. Press 
Menu to close the Password Protect menu.
If you lose the remote control, you will not be able to enter the 
password; so keep the remote control in a safe place at all times. You 
can store it in the compartment under the projector. See “Storing the 
Remote Control” on page 40.
When the period defined in the Time-elapsed setting has passed, and 
the password is entered correctly, the elapsed time will be reset to 
0 
and the countdown will start again. So remember to disable or change 
this setting when you need to.
Starting the Projector with a Password
When the password function is enabled, you see this screen when you 
turn on the projector: 
Use the numeric keypad buttons to enter the password that has been 
set. Once you have entered the password correctly, the password 
screen closes, and projection begins.
