*HAC (Hearing Aid Compatibility) devices are marked with “M” or “T” ratings to reflect how the wireless device will work with the hearing aid in microphone mode (“M”) and in the telecoil mode (“T”). Only phones that are tested and meet the minimum rating for HAC—“M3” or “T3”—and higher will be labeled. If you see an “M3,” “M4,” “T3,” or “T4,” the phone has been designated as HAC-compliant. The higher the “M” rating on the phone, the more likely it is you will be able to use the phone with your hearing aid on the microphone setting. The higher the “T” rating, the more likely you will be able to use the phone with your hearing aid on the telecoil setting. For more detailed information, consult your service provider or the manufacturer or visit Gari.info.
