When you first throw power supply “on”, all the lamps on the panel will be lit on. Confirm that
there are no lamps that are not lit. At the same time, the initialization pattern and the opening
message are displayed on the LCD screen, and then, the calibration and system-check windows
will be displayed on the screen. (The calibration window is for self-measurement to correct for
any errors.) After the system-check has been successfully completed, the window will
automatically be closed.
