* These handsets 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 other 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 your service provider or the manufacturer of the handset for information on hearing aid compatibility. If you have questions about return or exchange policies, consult your service provider or phone retailer.

Explanation of HAC and Rating System
Hearing Aid Compatibility (HAC) for Wireless Devices 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 using a telecoil to receive only audio signal-based magnetic fields generated by inductive coupling-capable telephones. The FCC’s "M" and "T" ratings are marked clearly on the handset packaging. The "M" or "T" rating does not guarantee that the handset will function without distortion or noise, so PTC Mobile recommends that you test the handset before purchasing. All handsets are available at the company’s retail outlets for testing. Agents can assist in testing and reviewing the features of each model.

Levels of Functionality
HAC-compliant phones are available at major price points which reflect levels of feature sophistication: lower priced phones (<$100) are most basic and denoted "C"; moderate-cost ($100-$250) have more advanced functionality and are denoted "B"; and high-end/feature-rich (>$250) generally are the most advanced, having wireless Internet capability and/or an operating system that supports advanced applications, denoted "A".
