1) Turn the GP’s power OFF (i.e. disconnect the GP's power cord).
2) Use a Phillips screwdriver to remove the case’s two rear attachment
screws, and pivot the rear cover open, starting from the top of the
unit. (The cover is fastened at the bottom, and hinges open)
• The rear cover cannot be completely removed. If you attempt to remove it,
you may break the cover.
3) Disconnect the upper backlight's power connector from the GP's
inverter.
4) Loosen the backlight holder's two attachment screws, and remove
the backlight's metal cover.
• Since the attachment screws are small, be sure not to lose them or allow
them to fall inside the GP's case.
This unit has two backlights, one at the top and one at the bottom. The follow-
ing explanation is for changing the top backlight. To change the bottom
backlight, simply repeat the procedures shown here in the same order.
• Be sure to change both backlights at the same time.
