Adjusting Signal Settings
Although the projector normally detects and optimizes the input 
signal automatically, you can use the Signal menu to make manual 
adjustments. In addition to changing the position of the projected 
image, you can correct tracking and sync for computer images, or 
change the aspect ratio to widescreen format for video images. 
1. Press the 
Menu button and select the Signal menu. 
You see a screen similar to one of those below. (The settings will 
be different depending on the source you are projecting from.)
2. Use the  pointer button to highlight the desired option, then 
adjust it as needed:
■Auto Setup 
Leave this setting 
On to automatically optimize computer 
images. Turn it off if you want to save adjustments you have 
made to the Tracking, Sync, and Position settings.
■Tracking 
Adjust this value to eliminate vertical stripes in computer 
images.
■Sync
Adjust this value if computer images appear blurry or flicker.
■Progressive
For composite video and S-video only. Turn this setting On 
to convert interlaced signals into progressive signals (best for 
still images). Leave the setting 
Off for moving images.
Computer/RGB Video
Composite Video/S-Video
note
You can also use the remote 
control’s 
Auto button to 
automatically reset the 
projector’s Tracking, Sync, 
and Position settings. See 
page 189 for details.

Customizing Projector Features
You can use the Settings menu to lock the buttons on the projector,

signals from the remote control. Use this setting to prevent use of 
the remote control or to stop interference from bright fluorescent 
lights.
■Test Pattern

and when performing keystone correction.
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 146. 
■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 148. 
note
You can also attach a 
security cable to the 
projector to prevent theft 
(see page 204).

Freeze button on the remote control for about five 
seconds. You see this screen:
2. Use the   pointer button to select

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 above, 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 page 146.
■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 146.
■Network Protect to lock the Network settings in the menu 
system (see page 59). 
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.

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

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 
and the projector switches to 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 197.
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. 
note
If you leave the projector 
plugged in, the Password 
Protect Release screen will 
not appear. It appears only 
if you unplug and reconnect 
the power cable.
