Disables all projector buttons (Full Lock) or all the buttons
except the P
Power button (Partial Lock). You can still
operate the projector from the remote control. Changes to
this setting take effect after you restart the projector. (After
you turn off the projector, wait for the power light to turn a
steady orange before turning it on again.) See page 70 for
more information.
■ Brightness Control
Select Low lamp brightness when the projection is too bright
for the room. The
Low setting also reduces electricity
consumption and fan noise. Select
High to project the
maximum brightness. (Also check the
Brightness setting in
the Image menu; see page 54.)
■ Volume
Adjusts the volume for the projector’s speaker.

Displays a test pattern to assist you in focusing and zooming
the image, and correcting the image shape. (To cancel the
displayed test pattern, press
Esc.)
