1 - The asterisked items (*) require further justification before permanent confidentiality will be allowed. These also currently

require review by the FCC under their Permit-But-Ask policy before the grant is issued and can delay completion of an

application. Further justification should be added to the note above. One such example for a potted device would be: “The

EUT is FULLY potted using a non-removable epoxy based material. Removal of potting material causes irreparable

damage to internal circuitry. See photographs exhibits that outline the device before and after potting.”
