Hearing Aid Compatibility - LG C395 User Manual

Hearing Aid Compatibility

(HAC) with Mobile Phones
When some mobile phones are used near
some hearing devices (hearing aids and
cochlear implants), users may detect a
buzzing, humming, or whining noise. Some
hearing devices are more immune than
others to this interference noise, and phones
also vary in the amount of interference they
generate. The wireless telephone industry has
developed ratings for some of their mobile
phones, to assist hearing device users in
finding phones that may be compatible with
their hearing devices. Not all phones have
been rated. Phones that are rated have the
rating on their box or a label on the box. The
ratings are not guarantees. Results will vary
depending on the user's hearing device and
hearing loss. If your hearing device happens
to be vulnerable to interference, you may not
be able to use a rated phone successfully.
Trying out the phone with your hearing
device is the best way to evaluate it for your
personal needs.
Safety Guidelines
M-Ratings: Phones rated M3 or M4 meet FCC
requirements and are likely to generate less
interference to hearing devices than phones
that are not labeled. 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 devices may also be measured for
immunity to this type of interference. Your
hearing device manufacturer or hearing
health professional may help you find results
for your hearing device. The more immune
your hearing aid is, the less likely you are to
experience interference noise from mobile
phones.
To ensure that the Hearing Aid Compatibility
rating for your phone is maintained, secondary
transmitters such as Bluetooth
must be disabled during a call.
