Adjust the Display
Brightness The 6181X-12TPXPDC display computer has an adjustable display brightness
setting that can be adjusted in the BIOS setup.
After applying power to the computer, press F2 during POST to enter the BIOS
setup. The display brightness default setting is 70%.
IMPORTANT When used in hazardous locations the computer supports peripheral
cards rated 4 W maximum, and Class I, Division 2, Groups A, B,C, D, T4.
At maximum product temperature a PCI card dissipating 4 W may
experience a surrounding air temperature up to 90 °C (194 °F). A PCI card
dissipating 1 W may experience a surrounding air temperature up to
85 °C (185 °F).
IMPORTANT Increasing the brightness from the default setting will reduce the life of
the LED backlight, particularly at high temperatures.
