Changing 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 BURNSOUT"
feature is set to "NO", the GP's touch panel will be disabled
The GP-377 Series unit uses a CCFL, 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. The GP-377 Series backlight has a life of 30,000
hours (appr. 3.4 years), when the backlight is lit 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 changing 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.
*1 If "NO" has been selected for the OFFLINE menu's "FORCE RESET" feature,
Touch-Panel operation is disabled.
