Using Your Phone With a Hearing Aid Device

A number of Sprint phones have been tested for hearing aid device compatibility. 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 LG
LS740 has an M4/T3 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.)
