22 Important Safety Information
When some wireless phones are used with certain
hearing devices (including hearing aids and cochlear
implants), users may detect a noise which can interfere
with the effectiveness of the hearing device.
Some hearing devices are more immune than others to
this interference noise, and phones also vary in the
amount of interference noise they may generate. ANSI
standard C63.19 was developed to provide a
standardized means of measuring both wireless phone
and hearing devices to determine usability rating
categories for both.
Ratings have been developed for mobile phones to
assist hearing device users find phones that may be
compatible with their hearing device. Not all phones
have been rated for compatibility with hearing devices.
Phones that have been rated have a label located on the
box.
Your Rise has an M4 and a T4 rating.
These ratings are not guarantees. Results will vary
depending on the user’s hearing device and individual
type and degree of hearing loss. If a hearing device is
particularly vulnerable to interference noise; even a
phone with a higher rating may still cause unacceptable
noise levels in the hearing device. 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 for hearing aid compatibility and are likely
to generate less interference to hearing devices than
unrated phones. (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’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 have
telecoils in them.)
Note: New Technologies, Including Wi-Fi
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
newer wireless technologies (including Wi-Fi) used in
this phone that have not been tested for use
with hearing aids.
Hearing aid devices may also be measured for immunity
to interference noise from wireless phones and should
have ratings similar to phones. Ask your hearing
healthcare professional for the rating of your hearing
aid. Add the rating of your hearing aid and your phone to
determine probable usability:
● Any combined rating equal to or greater than six
offers excellent use.
● Any combined rating equal to five is considered
normal use.
● Any combined rating equal to four is considered
usable.
