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: M3
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.
Hearing devices may also be measured for immunity to this
type of interference. Your hearing device manufacturer or
hearing health professional may help you find results for your
hearing device. The more immune your hearing aid is, the less
likely you are to experience interference noise from wireless
devices.
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment to an outlet on a circuit different from
that to which the receiver is connected.
