Using the Projector Security Features
To prevent unauthorized use of the projector, you can:
■Assign a password. You can use the password to prevent the 
projector from being turned on and prevent your custom startup 
screen from being changed. See the next section.
■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 71. 
■Disable the projector’s buttons; this is useful, for example, in a 
classroom when you want to ensure that no one touches the 
projector’s buttons while you’re using the remote control. See 
page 73. 
■Secure the projector to prevent theft using a cable locking system. 
See page 74.
