200011E4 — CW (continuous-wave) Doppler calibration problem
Philips CT error code, reported by the CW Doppler calibration.
What 200011E4 means
On CT systems, status code 200011E4 indicates: CW (continuous-wave) Doppler calibration problem. The code originates in the CW Doppler calibration section of the CW Doppler calibration. Severity level warning (Warning — CW calibration failed).
Reported action: Re-run the CW calibration for the scanhead in use. If calibration keeps failing, try a second CW-capable scanhead to separate a probe fault from a system fault, and check the Doppler signal path hardware if the failure follows the system rather than the probe. Expect CW Doppler measurements to be unreliable until this clears..
From the Philips ultrasound service reference "Error Logger Overview" (New Error Logger), archived under Philips ultrasound End-of-Life service documentation. The source lists this Errno as "Problem with CW calibration" (CW = continuous-wave Doppler). A full log entry combines a 4-digit Subsystem code with the Errno (format ssss-eeeeeeee); the same table lists 0203 Mode-Doppler among the subsystems.
