Using Your Phone With a Hearing Aid Device
Your T-Mobile
®
Concord™ is compliant with the FCC Hearing Aid Compatibility (HAC)
requirements. For additional HAC information, including the HAC rating of this product,
please refer to www.zteusa-support.com.
When some wireless 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 have been rated have a label on the box.
Your T-Mobile
®
Concord™ has been tested for hearing aid device compatibility and
has an M3/T3.
These ratings are not guaranteed. Results will vary, depending on the level of immunity of
your hearing device and the degree of your 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.
M-Ratings: Phones rated M3 or M4 meet FCC requirements and are likely to generate less
interference with 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 contain
telecoils.) The more immune your hearing aid device is, the less likely you are to
experience interference noise from your wireless phone.
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.
