T68 LED high-pitch buzzing sound

Howdy.

Does anyone else experience a high-pitched buzzing sound whenever they turn on their led light on the T68? I hear it on all levels except off.

No other e-reader I've tested exhibits this sort of additional sound effect.

Is this a defect just in my unit or a t68 "feature"?

And I though I was the only one who heard it!!

I bought two T68 devices. Both emitted this sound, however in one of them it was very faint and I could only hear it when putting my ear next to it and the other one had it so loud that whenever I read in a completely quiet room I kept hearing the sound all the time. I ended up replacing the one with the loud sound and the sound of the replacement unit it low enough so I don't hear it while reading.

And you are right - none of the other front-lit devices I had emitted such a noise.

Interesting, so it really is a defective product?

Attached is a sample of the soothing audio it produces. I reckon this isn't an issue for those that read on construction sites, during building demolition, on formula one racetracks or during riots, but a quiet room literally forces you to put in earplugs or play white noise to drown it out.

The high pitched noise is present in all 3 devices that I owned/own - unlike other front-lit devices I had that did not have any such noise (that I could hear).
However some T68's emitt stronger noise than others and if you, like me, can hear the noise in a quiet room, I suggest to replace it (but expect the noise to be present in the replacement unit too, albeit not as loud).

I can hear buzz when put device close to my ear.
