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 72.
■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 73. 
■Lock the network configuration settings. See page 71. 
If 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 of f 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 disconne cted and reinserted to redisplay 
the password screen. If an incorrect password is entered thirty times in 
succession, the user must contact Epso n to have the projector serviced. 
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. 
						

							
70Fine-Tuning the ProjectorThe default setting for the Password Protect function is 
Off. Follow 
these steps to turn password protection on:

Freeze button on the remote control for about five 
seconds. You see this screen:
2. Use the  pointer buttons 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.
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 72). 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). No ne of the User’s Logo features 
in the Extended menu can be changed when the User’s Logo 
Protect function is enabled.
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.
