&*en certain memory-resident programs are running, the screen’s backlighting cannot be restored after it has been turned off. If you find that the screen’s backlighting does not come back on when you press a key, you may want to set the backlight period to Not time limit. Another way to avoid this problem is to use the Epson LIGHTON utility. See chapter 5 for details on the LIGHTON utility.

When you have selected the backlighting period, highlight SAVE SETTINGS and press Enter. The main menu reappears.

The Gray scale option on the setup menu allows you to define the correspondence between colors and gray tones in gray-scale mode 3 (see Chapter 1). If you are not planning to use gray-scale mode 3, you do not need to set the Gray scale portion of the setup program.

To define gray-scale mode 3, highlight Gray scale on the setup main menu and press Enter. The following display appears:
