About hearing aid compatibility

Several BlackBerry devices have received certification from the United States Federal Communications Comission (FCC) stating that the devices meet the hearing aid compatibility requirements.

BlackBerry devices rated M3 or M4 meet FCC requirements and are likely to generate less interference with hearing devices than wireless devices that are not rated. M4 is the higher of the two ratings.

BlackBerry devices rated T3 or T4 meet FCC requirements and are likely to be more compatible with a hearing device's telecoil (T-coil, T Switch, or Telephone Switch) than wireless devices that are not rated. T4 is the higher of the two ratings. Not all hearing devices have telecoils in them.

Results might vary depending on the hearing device and the degree of hearing loss. If your hearing device is vulnerable to interference, you might not be able to use a rated wireless device successfully. The best way to evaluate compatibility of your hearing device and a rated wireless device is to test the devices together and consult with your hearing health professional.
