Hearing Aid Compatibility (HAC)
The phones listed above have been tested and rated for use with hearing aids for some of the wireless technologies that they use. However, there may be some newer wireless technologies used in these phones that have not been tested yet for use with hearing
aids. It is important to try the different features of these phones thoroughly and in different locations, using your hearing aid or cochlear implant, to determine if you hear any interfering noise. Consult RTI or the manufacturer of the phone for
information on hearing aid compatibility. If you have questions about return or exchange policies, please contact us.
Hearing aids do not always function well with wireless handsets. Hearing aids operate by using a microphone to pick
up sound waves, converting the sound waves into electrical signals to be amplified. Distortion or amplification of unwanted sound (noise) often occurs.
The FCC’s hearing aid compatibility requirements address hearing aids that
operate in either of two modes – acoustic coupling (“M” rating) or inductive coupling (“T” rating). Hearing aids operating in acoustic coupling mode receive through a microphone and then amplify all sounds surrounding
the user, including both desired sounds, such as a telephone’s audio signal, and unwanted ambient noise. Hearing aids operating in inductive coupling mode turn off the microphone to avoid amplifying unwanted ambient noise, instead of using a
telecoil to receive only audio signal-based magnetic fields generated by inductive coupling-capable telephones. The FCC’s “M” and “T” ratings indicate whether a handset can be expected to function well with a hearing
aid and are generally marked clearly on the handset packaging. The “M” or “T” rating does not guarantee that the handset will function without distortion or noise, so RTI recommends that you test the handset before purchasing.
