Manufacturer Narrative

This follow-up report is being submitted to relay additional information.The following sections were updated updated: g3; h2; h3; h6.Physical and technical evaluation was performed by a field service engineer (fse), and confirmed the appearance of unknown robotic errors that could not be resolved by multiple restarts.A log inspection discovered a disconnection of the force torque sensor from the arm related to the cable.The fse decided to replace the f/t sensor cable with one from a demo unit, and the errors were resolved.The fse went on to replace the f/t sensor as well and performed an arm accuracy and applicative test to ensure proper function.The unit was fully operational after repairs.Device history record (dhr) was reviewed and no deviations or anomalies were discovered.With the information currently available, a root cause for the malfunction of the force torque sensor and the force sensor cable resulting in disconnections cannot be definitively determined.If any further information is found which would change or alter any conclusions or information, a supplemental will be filed accordingly.Zimmer biomet will continue to monitor for trends.
