Is the system overheating? Look at the diagnostics light on the front
panel display (if present). Verify that the enclosure is properly
ventilated so the RAC6182 ambient operating temperature is within
specifications.
If there is a problem running new software:
Does the software have a hardware requirement that is not present?
Are you using an authorized copy of the software? Some copies of
software will not work without proper activation.
Did the software install correctly? Re-install the software.
Are you following the software's instructions? Refer to the software
vendor’s user manual.
If there is a problem with an add-in board:
Is the board installed and configured correctly? Recheck jumper and
other configuration settings.
Are any cables correctly installed?
Are the Windows CE drivers loaded for the add-in board?
If incorrect characters are displayed or are distorted:
Are the display contrast and brightness controls properly adjusted?
For information on configuring display settings, refer to Chapter 10,
Display Settings.
Is the monitor compatible with the selected video mode? The 7.7-in.
RAC6182 Industrial Computer LCD display is 640x480 (VGA)
resolution. The 12.1-in. display is 800x600 (SVGA) resolution.
If using the integrated display, open the RAC6182 chassis and check
the cable connections between the computer chassis and front bezel
assembly.
If characters are not displayed on an external monitor:
Is the monitor functioning properly?
Is the video cable properly installed?
Check that selected character color is not set the same as the
background color.
