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

Restricting Children's Access to Your Phone
Your phone is not a toy. Do not allow children to play with it as they could hurt
themselves and others, damage the phone, make inadvertent emergency
calls, or make other calls that may impact your Boost Mobile account.
Using Your Phone With a Hearing Aid
Device
A number of Boost Mobile 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 to 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 Innuendo™ 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
118 4A. Important Safety Information
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.
Boost Mobile further suggests you experiment with multiple phones (even
those not labeled M3/T3 or M4/T4) while in the store to find the one that
works best with your hearing aid device. Should you experience
interference or find the quality of service unsatisfactory after purchasing
your phone, promptly return it to the store. More information about hearing
aid compatibility may be found at: www.fcc.gov, www.fda.gov, and
