Using Your Phone With a Hearing Aid Device
Your Model name:F870E device 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.zte.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 Model name:F870E has been tested for hearing aid device compatibility and
has an M3 rating.
These ratings are not guarantees. 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 aid devices should have ratings similar to those of phones.
Ask your hearing health-care professional for the rating of your hearing aid.
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 wireless devices.
For additional information about the FCC's actions with regard to hearing aid compatible
wireless devices and other steps the FCC has taken to ensure that individuals with disabilities
have access to telecommunications services, please go to www.fcc.gov/cgb/dro.
