The XBT GT5000/6000/7000 series units’ backlight can be replaced by the

for details on how to replace the backlight. Contact your local XBT GT distributor for
more information.
How to
Determine if the
Backlight is
Burned Out
If your XBT GT unit's backlight suddenly turns OFF, use the following steps to
determine if the backlight is actually burned out:
If the XBT GT unit's "Backlight Control" is not set and the screen has gone blank,
your backlight is burned out.
If the XBT GT unit's "Backlight Control" is set to Standby Mode and the screen
has gone blank, and touching the screen or performing another input operation
does not cause the display to reappear, your backlight is burned out.
WARNING
RISK OF UNINTENDED EQUIPMENT OPERATION
Do not create XBT GT touch panel switches for system functions that may cause
injury and/or equipment damage.
If the XBT GT unit's backlight burns out and the unit is not set to Standby Mode,
the touch panel remains active. If the operator fails to notice that the backlight is
burned out and touches the panel, unintended equipment operation can occur.
Failure to follow this instruction can result in death, serious injury, or
equipment damage.
