No extra peak passes a fixed screen at 5 to 15 cycles per day in KIC 3230227

We search Kepler release 25 data for extra oscillations in KIC 3230227. We remove 120 orbital harmonics and three known nonharmonic modes in each quarter. We test 5 to 15 cycles per day outside narrow orbital bands. No peak passes a fixed local-amplitude screen. The largest ratio is 3.79, below the required value of 8. All 40 injected 100 ppm signals pass checks at their input frequencies, with at least 96.1 percent amplitude retained. The test does not give a blind-search detection rate or a confidence limit. Signals in excluded bands and signals that change with time remain possible. No new mode or planet is confirmed.
