CSIP Level 1 Troubleshooting: All Troubleshooting Starts Here
Clarifying
Symptoms
These actions and considerations can help to clearly describe a symptom, which is useful in iso-
lating the cause and can also be useful later when documenting the problem and the solution.
Make notes about the problem you are investigating as you read through this section:
• Have the user restate problem and verify that you are checking the correct system.
• Are there any other systems exhibiting this symptom or is it exclusive to one system?
• Is this the symptom of a real problem, or is it possibly an unrealistic expectation of the sys-
tem features and options set?
• Clarify the symptom: Is it a hang, a crash, a shutdown, an image artifact, an error code, not
booting, or other symptom? Write down a clear statement of what the symptom is and how
it manifests itself:
- How does it happen: What keystrokes, what modality, what preset, what transducer?
- When does it happen: Time of day, during boot-up, during scan, image review, sending to
a network, during a calculation, during a measurement, playing/recording VCR, printing,
acquiring an image, annotating, other?
- How often does it happen: Intermittently, predictably, all of the time?
• Categorize/localize the problem:
- Is it a printing problem, an image quality or viewing problem, a data export or import
problem, or other?
- Consider if the symptom indicates an operating procedural error or a system failure. If it
is a system failure, determine whether it seems to be a hardware or software problem. If
it is a software problem, determine if it is an operating system or ultrasound problem.
