HEARING AID COMPATIBILITY (HAC)
REGULATIONS FOR WIRELESS DEVICES US VARIANT ONLY
This device has been tested and rated for use with hearing aids, with some of the wireless technologies that it uses.
However, there may be newer wireless technologies used in the device that have not been tested yet for use with hearing
aids. It is important to try the different features on your device thoroughly and in different locations whilst using a hearing
aid or cochlear implant to determine if there is any interfering noise. Consult your service provider or the device manufacturer
for information on hearing aid compatibility. If you have any questions about return or exchange policies, consult your service
provider or phone retailer.
• The U.S. Federal Communications Commission (FCC) has established requirements for digital wireless mobile devices to
be compatible with hearing aids and other hearing assistive devices.
• The wireless telephone industry has developed a rating system to assist hearing device users, reviewing the compatibility
of mobile devices with hearing devices.
• The ratings are not guaranteed. Results will vary depending on the user’s hearing device and hearing loss. If a user’s
hearing devices happens to be vulnerable to interference, the user may not be able to use a rated phone device
successfully. Testing the mobile device with a hearing device is the best way to evaluate if it is suitable for a user’s
personal needs.
• The FCC has adopted HAC rules for digital wireless phones. These rules require certain devices to be tested and rated
under the American National Standard Institute (ANSI) C63.19-201 hearing aid compatibility standards. The ANSI
standard for hearing aid compatibility contains two types of ratings:
• M-Ratings: Phones rated M3 or M4 meet FCC requirements and are likely to generate less interference to hearing
devices than mobile devices that are not labelled. M4 is the better/higher of the two ratings.
• T-Ratings: Phones rated T3 or T4 meet FCC requirements and are likely to work better with a hearing device’s telecoil (“T
Switch” or “Telephone Switch”) than unrated phones. T4 is the better/ higher of the two ratings. (Note not all hearing
devices have telecoils in them.) The tested M-Rating and T-Rating for this device (FCC ID: ZL5S61), M3 and T3.
