Getting The Best Hearing Device Experience With Your Phone - Sanyo SCP-3810 Operating Manual

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 SCP-3810 by Sanyo has [M4/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.
•
Any combined rating equal to four is considered usable.
Thus, if you pair an M3 hearing aid with an M3 phone, you will have a combined rating of
six for "excellent use." This is synonymous for T ratings.

www.fda.gov, and www.accesswireless.org.
