  • Page 274  Test Description The keyboard testing interface is shown as follows: Note: in V4.0 new keyboard is added, the self-diagnosis screen will detect the keyboard version automatically and present the corresponding screen. The screen for new keyboard is as follows. As shown in the figure above, click [Start] to start the keyboard test.
  • Page 275 The encoder rotation test: the on the simulation keyboard corresponds to the encoder on the real keyboard. When you rotate the encoder in a direction, the corresponding green ball around the encoder on the simulation keyboard will rotate in the same direction. The encoder face will flicker and turn green or orange.
  • Page 276 Note: the above figure is for old keyboard test result. If the machine uses a new keyboard, then the new keyboard backlights are only white after test, as follows. In addition, there is a Arrow key on both the new keyboard and control panel, as long as you press one button, Arrow on the both keyboard and control panel will turn color and blink.
