US Information Concerning the Federal Communications
Commission ("FCC") Requirements for Hearing Aid Compatibility
with Wireless Devices
Applicable ratings for hearing device compatibility appear on the SKU label on the box that
came with this BlackBerry® device.
When wireless devices are used near hearing devices (such as 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, and wireless devices also vary in the amount of
interference they generate.
The wireless telephone industry has developed ratings to assist hearing device users in finding
wireless devices that may be compatible with their hearing devices. Not all wireless devices
have been rated. Wireless devices that are rated will have the rating displayed on their box
together with other relevant approval markings.
The ratings are not guarantees. Results will vary depending on the user's hearing device and
hearing loss. If your hearing device is vulnerable to interference, you may not be able to use a
rated wireless device successfully.
Consulting with your hearing health professional and testing the wireless device with your
hearing device is the best way to evaluate it for your personal needs.
How the ratings work
M-Ratings: Wireless devices rated M3 or M4 meet FCC requirements and are likely to generate
less interference to hearing devices than wireless devices that are not labeled. M4 is the better/
higher of the two ratings.
