Manufacturer Narrative

Plant investigation: the actual device was returned to the manufacturer for physical evaluation.An exterior visual inspection of the returned cycler showed no signs of physical damage.The screen brightness check failed - cycled through levels 1 to 10 and the brightness of the display remained too dark to be visible.It was identified that the cause for the dim screen was due to an internal short on the transformer (t1) on the inverter board.The inverter board is located on the rear of the touch screen.A known good inverter board was installed, and the display became fully operational.The functioning inverter board was removed at the completion of the investigation.There were no other visual discrepancies encountered during the internal inspection.A review of the device manufacturing records was conducted by the manufacturer.There were no deviations or non-conformances during the manufacturing process.In addition, a device history record (dhr) review was performed and verified that the results of the in-progress and final quality control (qc) testing met all requirements.Upon completion of the evaluation, the reported issue was confirmed and the cause was determined to be an internal short of the transformer on the inverter board.The cycler was refurbished following the evaluation.
