Getting Help If a Test Fails
If any test fails, you can get additional information as
follows:
■ Highlight the test that failed in the Run Tests dialog
box and press [Enter], or
■ Highlight the <Zoom> command button and press
[Enter].
If the diagnostic tests fail, the adapter may not be
defective. The problem may be incorrect option settings,

boards, or improper installation. Follow the steps below
to test the adapter further.
CAUTION: Make sure to turn the power off before
inserting or removing the adapter from the computer.
