At least two times today I have encountered tones on my 3-year-old OPN S1s that are not described in the manual. It is a 4-tone sound, first at frequency X, second a tad higher in frequency, the last two lower than the first tone. Immediately before these tones, which I hear in both aids, there was a sort of silence but not the silence one gets when the aids are turned off.
I only have 3 programs in the units, and I all the usual sounds operate as designed — i.e. start up and battery warnings and battery failure. Today’s tones were absolutely new to me and the manual tells me nothing.
Anyone have any guidance?
