## Discrepancy

F/O OXY MASK HOT MIKE WHEN MASK SELECTED.  SFOMM..ACTUALLY CONTINUOUS STUCK MIC ON F/O'S SIDE WITH ANY MIC AND ANY PTT SWITCH PUSHED.  SWAPPED AUD SEL PANEL AND AUD ACCESS UNIT, NO HELP.  DISCONNECTED GLARESHIELD PTT SWITCH NO HELP.  ALL EQUIP RECONNECTED AND IN ORIGINAL POSITIONS.  REPLACED F/O CREW OXYGEN MASK PER MM, OPS CHECK'S OKAY.
