■Keystone
Adjusts a distorted image from a trapezoid shape to rectangular.
■Auto Keystone
Automatically adjusts a distorted image from a trapezoid shape to rectangular when the projector’s foot is extended or retracted. (Not available when you’re projecting from the ceiling or using rear projection.) Select On or Off.
■Operation Lock
Disables all projector buttons (Full Lock) or all the buttons except the PPower button (Operation 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 PPower light to turn a steady orange before turning it on again.)
■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 53.)
■Volume
Adjusts the volume for the projector’s speaker.
■Remote Receiver
Deactivates the projector’s front and/or back sensors that detect signals from the remote control. This may be necessary to prevent interference from bright fluorescent lights.
■Test Pattern
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.)
