User's Manual

The built-in keypad is located on the back panel of the projector.
Note that on this keypad, each number key also has a second label indicating a
specific function ("SRC" or VID 2", e.g.). These second labels apply only in
presentation level, i.e., when there is no part of the menu system present.
