Field notes
The page separates water and dust routines rather than treating every muffled speaker the same: one uses 165 Hz pulses, the other sweeps from 165 to 300 Hz. It also offers a manual tone generator and a 20 Hz–20 kHz sound test. For physical cleaning, the guide recommends a soft, dry toothbrush and cautions against hair dryers and rice; it advises switching off a phone that was fully underwater.
