SYSTEM OPERATIONS

For confirming its own servicing status, the system automatically executes self diagnosis every day, and dis-
plays the result of the diagnosis on a system message. By this function, possible causes for trouble can be dis-
covered in an early stage and possible trouble can be prevented from remaining undetected.
