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 61).
■ Auto Keystone
(EX50/EX70 only)
Automatically compensates for keystone distortion when the
projector is tilted upward or downward. This feature is available
only when the projector is set for front projection (enabled by
default).
■ Zoom
(EX30 only)
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
P
power button. See page 72 for more
information.
■ Brightness Control
Lets you select from two levels of brightness. The
Low
setting
reduces power consumption and projector noise, and extends the
lamp’s operating life.
■ Volume
Raises or lowers the volume of the projector’s speaker.
