Using Your Phone With A Hearing Aid Device - Sanyo KATANA DLX User Manual

Using Your Phone With a Hearing Aid
Device
Your phone has 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 KATANA DLX by
SANYO has M4 and T4 ratings.
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.)
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.
