GLC2400/2500/2600 Series units use a CFL, long-life type backlight. The actual life
of the backlight however, will vary depending on the GLC’s operating conditions, and
replacement may be required. A GLC2400/2500/2600 Series backlight has a life of
50,000 hours (approx. 5.7 years, at 25
o
C and 24 hour operation), 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 GLC unit’s power
cord is unplugged from the power outlet prior to replac-
ing 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.

If NO has been selected for the OFFLINE menu’s FORCE RESET feature, the touch
