Operator Input Components
The TOUCH SCREEN MONITOR allows the operator to enter information for an exam into
the CR 825/850 SYSTEM. The display of the TOUCH SCREEN MONITOR has a menu and
control system with a TOUCH SCREEN OVERLAY.
The INTERNAL PC provides the screen format for each menu item selected. The TOUCH
SCREEN MONITOR enables the operator to select a displayed menu item or control by
touching the SCREEN. This action sends a command to the CR 825/850 SYSTEM. The
INTERNAL PC sends the necessary data to do that action. CONTROL BUTTONS on the
TOUCH SCREEN allow the user to select functions and to move to other menus or functions.
VIRTUAL KEYBOARDS for entering information into the CR 825/850 SYSTEM display on the
TOUCH SCREEN MONITOR. The configuration of the KEYBOARD is determined by the type
of information to be entered. Each KEYBOARD automatically displays when a menu item is
selected to enter data.
The system also uses typed input from a PHYSICAL KEYBOARD connected to the
INTERNAL PC.
