Error Question
What does TEST 04 FAILED mean on a GE AMX-Series mobile X-ray?
Short Answer

Test fails if they are not equal. Entering Calibration will give a more specific error code for the check sum failure. Error code 84 Hex is recorded in the Error Code for a failure.
Troubleshooting Steps
Check Calibration and RAM. Identify the affected calibration, correct it, and rerun checksum/calibration.
