Note

On the LCD display, this test is run with gray scale mode 2 in effect, regardless of how the DIP switches are currently set. Table 1-2, in Chapter 1, lists the mapping of colors to gray tones in mode 2.

To start this test, press 8 and then Enter. Press any key to display each screen. On the last screen, this prompt appears:

Is the display correct (Y/N)?

If all the colors are correct, press Y and Enter to end the test. If any color is displayed incorrectly, check the adjustment of your monitor (if you are using an external monitor) and be sure that both ends of the cable are plugged in firmly. If a problem still exists, press N and Enter to display the error message.
