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 find phones that may
be compatible with their hearing
86
devices. Not all phones have been
rated. Phones that are rated have
the rating on their box or a label
located 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 generate less interference
to hearing devices than phones
that are not labeled. T4 is the
better/higher of the two ratings.
