7.4 Replacing the Backlight
PS-G units use a CFL, long-life type backlight. The actual life of the backlight however, will vary depending
on the PS-G's operating conditions, and replacement may be required. A PS-G backlight has a life of 50,000
hours (approx. 5.7 years, at 25°C and 24 hour operation), when the backlight is lit continuously (time required
for brightness to fall to half its normal level.)
• When the LED setting is specified with the RAS control in Control Panel and a backlight
• If the backlight or the display unit is damaged, the screen display will go out. Even if the screen
goes out, however, there is a possibility that the touch panel is still operating correctly.
Therefore, since any type of touch panel contact could have an unexpected or dangerous effect
or result, be sure not to touch the screen when this condition occurs.
Whenever changing the backlight, be sure the PS-G's power cord has been disconnected and that the
unit is cooled down.
When the PS-G's power cord is connected and the PS-G is ON, high voltage runs through the wires in the
backlight area do not touch them!
When the PS-G's power has just been turned OFF, the backlight 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.
