Recall Action Recall for Product Correction
Recall Action Instructions Siemens has developed a new version of the 550 TxT Treatment Table software. In addition to the software update, Siemens is providing 550 TxT Treatment Table Addendum for the IFU that describes new table error codes. The software update will prevent the failure mode by the following actions:
1. A plausibility check was introduced for comparing the two independent encodersystems of each table axis.
2. The time between two encoder comparisons was reduced to 50ms and an error code was introduced.
