| Date | Jan 28, 2019 |
| Status | Open, Classified |
| Reason | The action is being initiated due to internal testing which identified a possibility for transducers to exceed the acoustic output power (AOP) values defined . The transit voltage values based on PW Doppler are calculated normally but not loaded correctly into hardware |
| Root cause | Software design |
| Action | A "Customer Safety Advisory Notification" letter was sent to customers on 04/04/2019 via email by Siemens Medical Solutions USA, Inc. The letter was released via update US038/18/S. The letter instructed customers to do the following: 1. To avoid a situation where incorrect acoustic output power values are used during pulsed wave Doppler, always press the UPDATE key prior to acquiring a real-time (live), pulsed wave Doppler spectrum. The ultrasound system updates the acoustic output power values to the correct values after each press of the key. 2. Do not use a simultaneous format for contin |
