CSIP Level 1 Troubleshooting: Symptoms, Causes, and Corrective Actions
Returning the
System to
Service
Once the reported problem is fixed and the system tests are successful, return the system to the
customer and close the call:
Formally document the problem and the solution: Write down exactly what problems you
discovered and what corrections you made.
Provide feedback: Communicate to all affected parties what problems you discovered, how
you arrived at that conclusion, and what corrections you made. Include this information with
parts that are returned for repair and, if appropriate, send e-mail with this information to ISS
personnel who could find it useful.
Symptoms,
Causes, and
Corrective
Actions
Some problem considerations are documented here.
Disk is Full
In this release, the system does not automatically manage hard drive disk space. That is, studies
are not automatically deleted as the hard drive disk becomes full. If the disk space alloted for
studies is filled, the system may behave erratically or generate errors.
Checking for
EMI and RFI
Electromagnetic interference (EMI) and radio frequency interference (RFI) can degrade the per-
formance of the HD3. For example, a transducer placed close to an ECG cable can increase
interference. Moving the ECG cable or other medical equipment away from the transducer can
reduce interference. EMI and RFI can conceivably cause image noise or monitor distortion if the
system EMI shielding has been compromised. EMI and RFI can be generated by a variety of elec-
trical devices. The interference can be transmitted over power lines or radiated through the air.
Answering the following questions can help locate the source of interference and help determine
whether the problem is with the system or with the scanning environment.
