Using the Projector’s Security Features
To prevent unauthorized use of the projector, you can do the
following:
■
Create an identifying user logo that is displayed at startup and/or
when the
A/V Mute
button is pressed
■
Assign a password; this can be disabled for a set period if you want
to loan the projector to someone
■
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
If you create a user’s logo for the projector, you can lock the logo on so
it is displayed as the startup screen and/or AV/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.
