perform the backlight changeover on a flat, level surface. This will prevent damage
to the GP unit and the accidental cutting of any of its power cord.
• Be sure to protect the display surface to prevent damage during the operations.
• Do not let the attachment screws fall inside the GP, or lose them.
• A hot circuit board chassis can burn you. Be sure the chassis has cooled completely
prior to replacing the backlights.
