Energising the terminal

green LED starts flashing and after approximately 30 seconds the window lights up. After an-
other 10 seconds the window displays 'Terminal Startup' and after about 30 seconds the main
menu is displayed. The upper row should indicate 'Ready'. A steady green light indicates a suc-
cessful startup.
