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 device has been tested for
hearing aid device compatibility and has an M3 and/or T3 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.
Important: This device does not support VoIP. WLAN and Bluetooth do not have voice
capability for held-to-the-ear phone service.
Note: 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.

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
