Hearing aid compatibility with digital wireless devices
To choose a digital wireless device, a "pairing" system combines a value for radio frequency RF emissions in the mobile phone and a rating for the immunity level in the hearing aid. Lower RF emissions in handsets and higher immunity in hearing aids may help reduce interference.
A combined rating of "5" is an acceptable minimum for "normal use," or probable use without buzzing or interference. The higher the combined ratings — adding the immunity rating of your hearing aid to the emissions rating (or telecoil coupling capability rating) of your wireless handset — the less interference you may experience.
Mobile phones for use with hearing aids
If you use your hearing aid in Microphone mode (M), look for a phone with an M3 or M4 rating. If you prefer telecoil coupling (T), look for a phone with T3 or T4 rating.
Hearing aids for use with wireless devices
Hearing aids for use with wireless devices should have an immunity rating of M2 at a minimum. Because hearing aids are custom devices, however, it may not be possible to know the exact rating. If the immunity rating of your hearing aid is not available, ask your hearing aid manufacturer or audiologist if your hearing aid includes cell phone shielding or has increased immunity to RF interference.
When paired with a hearing aid with a minimum M2 immunity rating, the following Nokia devices are recommended for compatible use.
|Nokia Lumia 521||M3/T4|
|Nokia Lumia 710||M3/T3|
|Nokia Lumia 810||M3/T3|
|Nokia Lumia 820||M3/T4|
|Nokia Lumia 822||M3/T4|
|Nokia Lumia 900||M3/T4|
|Nokia Lumia 920||M3/T3|
|Nokia Lumia 925||M3/T3|
|Nokia Lumia 928||M3/T4|
|Nokia Lumia 1020||M3/T4|
Please check with your service provider for availability. Devices with HAC ratings are available only in the United States.
