Software issues with ACUSON SC2000 ultrasound with software version 3/5 (VA35) - may incorrectly display the color flow data in the wrong position and when Doppler Frequency is adjusted, the system does not restart the pulsed wave Doppler or continuous wave Doppler waveform.

Distributors in foreign countries will implement delivery of notification to their customers. " Use the factory default presets with software version 3.5 instead of user-defined presets restored from software version 2.0 or 3.0. Review all patient studies on exams performed after software revision 3.5 was installed on your system. If you are unsure when this software was installed on your system, please contact your local Customer Service representative. " After adjusting the Doppler frequency, freeze and unfreeze the system. This action refreshes the display of the Doppler spectrum resulting in accurate measurements. Additional measurements performed after system freeze results in correct measurement values.

If you have any questions, please contact your local service support person for information regarding timelines and status.
