The installation gasket protects the PL and improves its water resistance. For
instructions on installing the PL’s gasket.
4-2 Installing the PL
A gasket which has been used for a long period of time may have scratches
or dirt on it, and could have lost much of its water resistance. Be sure to
change the gasket periodically (or when scratches or dirt become visible).

Replacing the Backlight
The PL’s backlight can be changed after it wears out. Follow the steps explained
below.
Please use the following table to identify which backlight model number to use when
ordering your backlight.
• Whenever changing the backlight, be sure the PL's power
cord has been disconnected and that the unit is cooled
down.
• When the PL's power cord is connected and the PL is ON,
high voltage runs through the wires in the backlight area—
do not touch them!
• When the PL's power has just been turned OFF, the back-
light area is still very hot! Be sure to wear gloves to pre-
vent being burned.
• Do not try to replace the backlight while the PL is installed
in a cabinet or panel. Remove the PL first, then begin the
backlight replacement procedures.
• Be careful when handling the backlight, since it is made of
glass and very fragile.
