Issues with the Add-in Card
• Is the card installed and configured correctly? Verify the jumper and other
configuration settings.
• Are the card cables properly connected?
• Is the add-in card recognized in Device Manager?
• A card issue that is not listed here? See troubleshooting information
supplied by the add-in card manufacturer.
• Verify that the card is not overheating.
Issues with the Integrated Display
• Check that the selected character color is not the same as the background

Restart the Computer on page 33 .
b. During POST, press F2 to access the BIOS set-up utility.
c. Use the BIOS set-up utility to adjust the display brightness.
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.
For ATEX and IECEx applications, operation in Group IIC Category 3 gas
and dust environments is supported.
At maximum computer temperature, consider the following:
• A PCI card dissipating 4 W can experience a surrounding air
temperature up to 90 °C (194 °F
)
.
• A PCI card dissipating 1 W can experience a surrounding air
temperature up to 85 °C (185 °F
)
.
TIP
Use the arrow keys on a keyboard to navigate between BIOS menus
and menu selections.
IMPORTANT
The default setting for display brightness is 70%. Brightness
increased above the default setting reduces the life of the
backlight, particularly at high temperatures.
