144 Fine-Tuning the Projector
■ Remote Receiver
Deactivates the projector’s front and/or back sensors that detect
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
Displays a test pattern for use when adjusting the zoom and focus,
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).
