No one can help you if you need service outside North America -- if you're a world traveller, just throw the thing away. ME is also drastically overpriced.
The franchisee who sold me mine assumed I wouldn't have any worsening of my hearing -- indeed, that was a selling point ("a hearing aid will keep your hearing from getting worse ..."). Just 16 months later my hearing has diminished beyond the range of this ME aid.
Unlike other brands (as I have now belatedly learned) the receivers can't be swapped out to increase its range. I will now throw away that $2442 spent on ME, get a good respected brand that offers worldwide servicing (including adjusting to worse hearing) for literally less than half the money.
