The investigation included review of the complaint information, product historical data, and product labeling review.Per complaint information, return parts were not available because they were discarded due to waste liquid that soaked these parts.Review of product historical data for any trends and all customer complaints received for this issue did not identify any adverse trends or abnormal complaint activity.In this case, field service found liquid behind the unit caused by the waste line not being seated correctly.The ground fault interrupter (gfi) was tripped from liquid hitting the ac/dc power supply and caused sparks.Tripping of the gfi causes the power to immediately shut off to the outlet and any outlets along the circuit.Field service replaced the 70w switching power adapter because it got wet with waste material.The waste line was reseated to correct the waste leak and to prevent future occurrences.The cell-dyn emerald operator's manual states "place the ac adapter/transformer in a well-ventilated location at the rear of the instrument, away from any potential liquid spills." review of labeling concluded that the issue is sufficiently addressed.The incident was instrument-specific.No product deficiency was identified.
