This could in the worst-case result in erroneous dose delivery. This issue affects Catalyst+ HD and Catalyst HD systems, configured for cSRS and cMotion. Customers are instructed to: 1. Ensure that all the staff operating the Catalyst+ HD and Catalyst HD, and the c4D software application are informed of this information. 2. As an immediate action, affected users are advised to not use Catalyst+ HD and Catalyst HD in combination with cSRS and cMotion.
