Adjusting Screen Brightness

CAUTION
• All or part of the screen may sometimes become darker or lighter because of changes in the

air temperature or other changes in the environment around the screen. This is normal and is
not a sign of malfunction. Adjust the screen if it is difficult to read.

• The screen may be dark immediately after turning on the power. This is a function of the LCD

back light screen, and it is not a sign of malfunction. The screen will return to its normal level
of brightness after approximately 10 minutes.

• If you are not directly in front of the machine when you view the LCD, the colors may appear

to change or the screen may be difficult to see. This is a characteristic of the LCD, and not a
sign of damage or malfunction. For best results operate the screen while sitting in front of the
machine.
