ActionThe following Notice of Correction letter was sent out to all customers via email on 9/12/13, and followed up with a direct phone call to confirm receipt and review the contents of the letter: Dear Dr. [Customer name], This email is to inform you of a pending notice of correction regarding your Solea system, serial #[Customer serial number]. We have identified a specific error condition that could lead to unintended laser emission during laser activation. The software defect that caused the error condition has been identified and tested. Please do not use your Solea system until further notice. Resolution of this issue will require the installation of an updated release of the Solea software. A representative from Convergent Dental will be in touch with you to schedule the upgrade. Convergent Dental is committed to product quality and patient safety. If you have questions about this issue, please contact us. Software fix and testing: New software version (Release 2.0.4.0) was created by the software development group. Convergent Dental has implemented two software changes to eliminate this problem. The first is a defect fix to correct the handling of fatal errors, specifically laser communication timeout errors, so that these errors are not able to be cleared. This will prevent the user from being able to re-enter the workflow after a fatal error. The second is a defect fix to not set the laser state to disconnected when a laser timeout error condition occurs. This will ensure that the command to stop laser emission is always sent to the laser control module anytime the laser cutting state is exited due to error condition or the normal workflow event of stepping off the foot pedal. The software development team ran full Unit and Integration Tests on the new software build. The software verification activities included execution of the full verification test plan (Doc #790-00001), which has been revised to include specific defect
