    DEVICE EVALUATED BY MFR: THE RESULTS OF THE TESTING INDICATED THAT THE RETURNED CARTO CABLE AS WELL AS THE ASSOCIATED CLEARSIGN AMPLIFIER PASSED INCOMING INSPECTION TESTS, INCLUDING NOISE AND LEAKAGE TESTING. THE CABLE SHIELDING CONNECTION WAS VERIFIED BY MEASURING THE CAPACITANCE AND IMPEDANCE AND RESULTS WERE SIMILAR TO THE CONTROL CABLE. THE POSSIBILITY OF INTERACTION EFFECTS BETWEEN THE TWO COMPONENTS AS A CAUSE WAS ELIMINATED BY TESTING THE RETURNED COMPLAINT AMPLIFIER AND CABLE TOGETHER AND FOUND NO ISSUES. BOTH DEVICES PERFORMED AS EXPECTED. THE BATCH NUMBER IS UNKNOWN AND THE MANUFACTURING RECORDS FOR THE COMPLAINT DEVICE COULD NOT BE REVIEWED. THE MOST PROBABLE CAUSE OF THE REPORTED DIFFICULTIES MAY BE DUE INTERACTION WITH ANOTHER DEVICE. (B)(4).
