Replacing the Backlight

When the unit's backlight burns out, the unit's status LED will turn orange. If the
OFFLINE menu's "USE TOUCHPANEL AFTER BACKLIGHT BURNS OUT"
feature is set to "NO", the GP's touch panel will be disabled.
GP2000 Series units use a CFL, long-life type backlight. The actual life of the
backlight however, will vary depending on the GP's operating conditions, and
replacement may be required. A GP2000 Series backlight has a life of 50,000
hours (approx. 5.7 years, at 25
continuously (time required for brightness to fall to half its normal level.)
• To prevent an electric shock, be sure the GP's power cord
is unplugged from the power outlet prior to replacing the
backlight.
• When the power has just been turned OFF, the unit and
backlight are still very hot. Be sure to use gloves to pre-
vent burns.
• 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.
Use the following table to check that you have ordered the correct backlight.
The GP2500L's backlights cannot be replaced by the customer.
When the backlights need to be replaced, please contact your local GP
distributor.
For backlight replacement details, refer to the replacement backlight
unit's installation guide.
*1 If "NO" has been selected for the OFFLINE menu's "FORCE RESET" feature,
Touch-Panel operation is disabled.
