Customizing Projector Features
You can use the Settings menu to lock the buttons on the projector,
adjust audio volume, and customize several other features.
■ Keystone
Adjusts the shape of the image if the projector has been tilted
upward or downward. If you notice that lines or edge look jagged
after adjustment, decrease the
Sharpness setting (see page 45).
■ Zoom
Adjusts the image size from Wide (larger) to Tele (smaller).
■ Control Panel Lock
Lets you disable all of the buttons on the projector, or all of the
buttons except the Ppower button. See page 55 for more
information.

reduces power consumption and projector noise, and extends the
lamp’s operating life.
