Cable Connection Checks; Powering Off The System - Webster IRP 4100 Installation Manual

From this point on you can use you IRP 4500 as your computer
desktop interface. Your keyboard and mouse should operate with
the IRP 4500 display screen just as they would with a regular display
monitor. Sound and sound control should be available on the
various speakers and user interfaces, depending on your particular
configuration.
However, the image on the screen may not yet be properly aligned,
and you cannot yet use your electronic pen as a substitute for the
mouse. To align the system, refer to "Image Adjustments" on
page 23.
You may want to adjust the projector main lens focus in a preliminary
fashion to be able to carry out the steps in this subsection.
