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 the 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.

This BlackBerry® device has been tested and rated for use with hearing aids for some of the

wireless technologies that the BlackBerry device uses. However, other wireless technologies

may be used in this BlackBerry device that have not been tested for use with hearing aids. It is

important to try the different features of your BlackBerry thoroughly and in different locations

to determine if you hear any interfering noise when using this BlackBerry device with your

hearing aid or cochlear implant. Consult your service provider about its return and exchange

policies and for information on hearing aid compatibility.

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.

T-Ratings: Wireless devices 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 wireless

devices. T4 is the better/higher of the two ratings. (Note that not all hearing devices have

telecoils in them.)
