- Siemens sent an Medical Device Correction, Field Safety Notice of Improvement to End users in March 2014, informing them that a Siemens representative would install a software update. By installation of this software update the issues were solved by the following actions: 1. A plausibility check was introduced for comparing the two independent encoder systems of each table axis. 2. The time between two encoder comparisons was reduced to 50ms and an error code was introduced. Please include this Field Safety Notice in your Digital Linear Accelerator System Owner Manual chapter "Safety Advisory Letters" where it should remain. The relevant National Competent Authority has been informed of this update. We regret any inconvenience that this may cause, and we thank you in advance for your understanding. Further questions please call (610) 219-6300.
