1. Cautions for Backlight Lamp Unit Replacement

 The backlight lamps used in the listed Liquid Crystal Display (LCD) modules are

consumables. Follow the included replacement procedures when replacing these
components.

 Disconnect AC power before starting the replacement procedure. The high

voltage applied to the backlight lamps produces an electrical shock hazard if
caution is not used when servicing this area.

 Backlight lamp units are fragile and caution should be used when handling.
 Ferrite cores are attached to the backlight lamp units with double-sided adhesive

tape. Use caution when removing these ferrite cores, as excessive force may
cause damage.

 Where possible, replace backlight lamp units in a clean and dust-free environment.
