Hearing Aid Compatibility (HAC) with Wireless Phones

Hearing aid users may hear buzzing, humming or whining noises when using certain mobile telephones due to microphone radio frequency (acoustic) interference, or telecoil electromechanical (inductive) interference.

FCC rules require the availability of phones that limit acoustic and electromechanical interference. Phones that meet a minimum rating of M3 or M4 will be labeled for HAC compliance for acoustic coupling; phones that meet a minimum rating of T3 or T4 will be labeled for HAC compliance for inductive coupling.

The packaging for hearing aid compatible phones will indicate the device’s “M” and “T” rating; the higher the “M” rating, the more likely you will be able to use the phone with your hearing aid on its microphone setting; the higher the “T” rating, the more likely you will be able to use the phone with your hearing aid on its telecoil setting. Ratings are not guaranteed.

Many hearing aids also are rated to measure their vulnerability to radiofrequency interference. This “immunity” rating is currently voluntary, so you should consult your hearing health professional or the hearing device manufacturer for more information. Mid-Rivers Wireless attempts to maintain a full selection of compliant handsets across all levels of functionality but may, from time to time, be unable to meet that goal due to limitations in the availability of handsets from suppliers

Interference may be minimized or eliminated depending on the combination of hearing aid devices with digital mobile telephones, so TRY BEFORE YOU BUY!

**Mid-Rivers assigns each compliant handset a level of functionality based upon the company's assessment of two factors: price and operating features. Lower-priced handsets with fundamental capabilities are defined as "Basic." More advanced functions or functionality, such as the availability of a better-quality camera, enhanced memory, or entry-level smartphone functionality, together with a higher price, result in classifying a handset as "Intermediate." More expensive phones with the newest technology and/or functionality are defined as "Advanced." Classifications are reviewed periodically, and specific handsets may be subject to reclassification based upon the then-existing spectrum of relative functionalities. Mid-Rivers Wireless attempts to maintain a full selection of compliant handsets across all levels of functionality but may, from time to time, be unable to meet that goal due to limitations in the availability of handsets from suppliers.

***This phone has been tested and rated for use with hearing aids for some of the wireless technologies that it uses. However, there may be some newer wireless technologies used in this phone that have not been tested yet for use with hearing aids. It is important to try the different features of this phone 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 this phone for information on hearing aid compatibility. If you have questions about return or exchange policies, consult your service provider or phone retailer.
