US Information Concerning the Federal Communications Commission (“FCC”)
Requirements for Hearing Aid Compatibility with Wireless Devices
When wireless devices are used near hearing devices (such as hearing aids and cochlear implants),
users may detect a buzzing, humming, or whining noise. Some hearing devices are more immune
than others to this interference, and wireless devices also vary in the amount of interference that
they generate.
The wireless telephone industry has developed ratings to assist hearing device users in finding
wireless devices that may be compatible with their hearing devices. Not all wireless devices have
been rated. Wireless devices that are rated will have the rating displayed on the box together with
other relevant approval markings.
The ratings are not guarantees. Results will vary depending on the user’s hearing device and hearing
loss. If your hearing device is vulnerable to interference, you may not be able to use a rated wireless
device successfully. Consulting with your hearing health professional and testing the wireless device
with your hearing device is the best way to evaluate it for your personal needs.
This smartphone has been tested and rated for use with hearing aids for some of the wireless
technologies that the smartphone uses. However, other wireless technologies may be used in this
smartphone that have not been tested for use with hearing aids. It is important to try the different
features of your smartphone thoroughly and in different locations to determine if you hear any
interfering noise when using this smartphone with your hearing aid or cochlear implant. Consult
your wireless service provider about its return and exchange policies, and for information about
hearing aid compatibility.
Hearing aid compatibility rating for this smartphone: M4/T4
How the ratings work
M-Ratings: Wireless devices rated M3 or M4 meet FCC requirements and are likely to generate
less interference to hearing devices than wireless devices that are not labeled. M4 is the better or
higher of the two ratings.
