Using Your BlackBerry® 8830 With a Hearing Aid Device
Your BlackBerry® device has been tested for hearing aid device compatibility. When some wireless devices are used near some hearing devices (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 noise and wireless devices also vary in the amount of interference they generate.
The wireless telephone industry has developed ratings for some of their wireless devices, 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 have been rated have a label located on the box. Your
BlackBerry® 8830 World Edition smartphone has an M4/T4 rating.
These ratings are not guarantees. Results will vary depending on the level of immunity of your hearing device and degree of your hearing loss. If your hearing device happens to be vulnerable to interference, you may not be able to use a rated wireless device successfully. Trying out the wireless device with your hearing device is the best way to evaluate it for your personal needs.
