PanelView 550 Backlight Lamp Replacement
(Catalog No. 2711-NL1)
This instruction sheet shows backlight replacement for Series A, Rev. E and later
PanelView 550 Terminals.
The Backlight Lamp illuminates the LCD display of the PanelView 550 Terminal.
Light from the lamp is transferred to the front panel through a fiber-optic bundle.
An infrared filter prevents heat from damaging the fiber-optic bundle.
Important: Make sure that the lamp and fiber-optic bundle do not touch the
infrared filter.
Refer to this illustration when using the procedures on the following page:

ATTENTION: The replacement backlight lamp is provided with a
lamp base. For terminals with a metal lamp clip (see illustration

terminal with a plastic lamp mounting ring, you do not need the lamp
base we provided.
!
ATTENTION: When operating, the backlight lamp is extremely hot.
Do not touch lamp or mounting clip when lamp is on. Allow lamp to
cool to avoid personal injury.
