Hearing Aid Compatibility With Mobile Phones - Samsung SGH-F278i User Manual

Hearing Aid Compatibility with Mobile
Phones
When some mobile 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
ratings for some of their mobile 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 on the box.
The ratings are not guarantees. Results will vary
depending on the user's hearing device and 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.
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.
T-Ratings: Phones rated T3 or T4 meet FCC
requirements and are likely to be more usable with a
hearing device°Øs telecoil (± Switch± or ±Telephone
Switch±) than unrated phones. T4 is the better/
higher of the two ratings. (Note that not all hearing
devices have telecoils in them.)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 mobile phones.
