Customizing Projector Features
You can use the Settings menu to lock the buttons on the projector, 
adjust audio volume, and customize several other features.
■Keystone 
Squares up the shape of the image after the projector has been 
tilted upward. If you notice lines or edges looking jagged after 
adjusting the shape, decrease the Sharpness setting (see page 100). 
■Auto Keystone
Automatically compensates for keystone distortion when the 
projector is tilted upward. This feature is available only when the 
projector is set for front projection (it is enabled by default).
■Control Panel Lock
Lets you disable the buttons on the projector. See page 110 for 
more information.
■Pointer Shape
Lets you choose from three alternative pointer shapes. See page 36 
for more information.
■Brightness Control
Lets you select from two levels of brightness. The Low setting 
reduces power consumption and noise, and extends the lamp’s 
operating life.
■Volume
Raises or lowers the volume of the projector’s speaker.

You can also adjust the 
volume using the remote 
control.

equipment (connected as shown on page 50).
■Remote Receiver

the remote control or to stop interference from bright fluorescent 
lights. Restart the projector for this setting to take effect.

Using the Projector Security Features
To prevent unauthorized use of the projector, you can do the 
following:
■Assign a password; this can be disabled for a set period if you want 
to loan the projector to someone. 
■Create an identifying user logo that is displayed at startup and/or 
when the 
A/V Mute button is pressed. See page 108.
■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 110. 
■Lock the network configuration settings. See page 107.  
						

							106Fine-Tuning the ProjectorIf you create a user’s logo for the projector, you can set up the logo so 
it is displayed as the startup screen and/or A/V 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. 
Enabling Password Protection
To prevent unauthorized use, you can assign the projector a password. 
If you do, a screen will appear 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. If an incorrect password is entered thirty times in 
succession, the user must contact Epson to unlock the projector. 
The default setting for the Password Protect 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 
Power On Protect to On. 
Then press 
Enter.
3. Press 
Esc.
4. Select Password and press Enter.
5. When you see a message asking if you want to change the 
password, select 
Yes and press Enter.
note
It’s a good idea to write 
down your password. 
If you leave the projector 
plugged in, the Password 
Protect Release screen will 
not appear. You only need a 
password if you unplug and 
reconnect the power cable.
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.

6. 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.) 
7. When you see a confirmation message, reenter the password. 
Then press the 
Menu button to exit the screen.
8. 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 you turn on 
the projector (if the 
Startup Screen is enabled in the Extended 
menu; see page 108). It also appears when you press the 
A/V Mute button (if you selected the Logo for the A/V Mute 
setting under Display in the Extended menu). None of the User’s 
Logo features in the Extended menu can be changed when the 
User’s Logo Protect function is enabled.
9. To enable network setting protection, select 
Network Protect 
and press 
Enter. Select On and press Enter. 
When this feature is on, none of the network settings on the 
Configuration menu can be changed. 
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, the numeric keypad is automatically 
deactivated, and projection begins. 
						

							108Fine-Tuning the ProjectorIf 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
 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 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 Protect Release screen for 
assistance. See “Where To Get Help” on page 138.
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 on the remote control, highlight the 
Extended menu, and press Enter.
note
Once you capture an image, 
it automatically replaces the 
Epson startup screen. 
Although you can change the 
startup screen, you cannot 
restore the original one.
