WARNINGS
• Be sure the GP/GLC's power cord has been disconnected prior to chang-
ing the backlight. When the GP/GLC's power cord is connected and the
GP/GLC is ON, high voltage runs through the wires in the backlight area -
do not touch them!
• When the GP/GLC's power cord has just been disconnected, the back-
light area is still very hot! Be sure to wear gloves to prevent being burned.
• The backlight is very fragile. Do not touch the glass tube directly or try to
remove its power cord. If the glass tube breaks you may be injured.
