The speed indicator on the status bar shows your operating
speed (16 MHz), and after a few seconds the computer begins to
perform an internal self test. This is a diagnostic program the
computer runs whenever you turn it on. The power-on self test
checks the RAM (random access memory), keyboard, system
board, and peripheral interfaces before the computer begins
normal operation.
Adjusting Screen Contrast and Brightness
If you cannot see text on the screen clearly, use the levers on
the right side of the screen to adjust the screen’s contrast and
brightness. The levers are shown below:

The contrast lever on the right determines how bright the
characters appear against the background. To increase the
contrast, move the lever up. To decrease it, move the lever down.
The brightness lever on the left controls the intensity of the
screen’s backlighting. To make the backlighting brighter, move
the lever up. To decrease the backlighting, move the lever
down. When you’re running the computer on the battery, do
not make the screen brighter than necessary to read the text
clearly. This helps to conserve the battery’s charge.
