Using the projector security features
To prevent unauthorized use of the projector, you can:
■ 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 51 for information on creating
your own startup screen.
■ Lock the projector with a password, or enable your iPod to act as a key. For more
information, see page 53.
■ 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 52 for more information.
■ Secure the projector to prevent theft using a cable locking system. See page 56 for more
information.
