Once you’ve powered up the computer, the small red light near the top right corner of the front of the main unit comes on and the cooling fan starts up (you can hear it). You may also notice that a number of small red lights on your keyboard blink on and off. This indicates that your QX-10 is performing an internal self- diagnostic test.

The small red light to the right of drive A also comes on, and the message INSERT DISKETTE appears on the monitor screen. (If any other message appears, see Chapter 4, “Troubleshooting.“)

INERT DISKETTE

If the brightness on the screen isn’t the way you like it, reach around to the back of the right side of the monitor until you feel the control knob near the bottom. Turning the knob clockwise increases the brightness; turning it counterclockwise decreases it. Experiment a bit to find the most comfortable brightness for you.

Before we go any further, we need to explain the concept of booting, so let’s proceed!
