FOR YOUR SAFETY
While some wireless phones are used near some hearing devices (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 noise and phones also vary in the amount of interference they
generate. The wireless telephone industry has developed a rating system for
wireless phones to assist hearing device users in finding phones that may
be compatible with their hearing devices. Not all phones have been rated.
Phones that are rated have the rating on their box or a label located on the
box. These ratings are not guaranteed. Results will vary, depending on the
level of immunity of your hearing device and the degree of your hearing loss.
If your hearing device happens to be vulnerable to interference, you may not
be able to use a rated phone successfully. Trying out the phone with your
hearing device is the best way to evaluate it for your personal needs.
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.
M-Ratings: Phones rated M3 or M4 meet FCC requirements and are likely
to generate less interference to hearing devices than phones that are not
labeled. M4 is the better/higher of the two ratings.
142
T-Ratings: Phones rated T3 or T4 meet FCC requirements and are likely to
be more usable with a hearing device's telecoil ("T Switch" or "Telephone
Switch") than unrated phones. T4 is the better/higher of the two ratings. (Note
that not all hearing devices contain telecoils.)
Your phone has been tested for hearing aid device compatibility and has an
M4/T3 rating.
Hearing devices may also be rated. Your hearing device manufacturer or
hearing health professional may help you find this rating.
