(cont’d)
• If errors were identified but the results were marginal, perform calibration, as described in
“DC Offset Calibration” on page 7-27 , and then repeat the test.
• If errors were identified and the results were not marginal, verify that all system cables and
boards are connected (not misplaced) and functioning properly, as described in Chapter 5 -
Components and Function (Theory) .
If the problem persists, this indicates that either the specific board you tested is faulty or that
another board that supports the operation of this board is faulty. Contact your local
GE HEALTHCARE field engineer for assistance.
