Using Your Phone with a Hearing Aid Device
Your Sprint PCS® phone has been tested for hearing aid device compatibility. When
some wireless phones 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 phones also vary in
the amount of interference they generate.
The wireless telephone industry has developed ratings for some of their mobile phones, to
assist hearing device users in finding phones that may be compatible with their hearing
devices. Not all phones have been rated. Phones that are rated will have the rating on the
box. Your [insert phone model here] has an [insert rating here] rating.
Note: Phones rated M3 or M4 meet FCC requirements and may generate less
interference to hearing devices than phones that are not labeled. M4 is the better/higher
of the two ratings.
The ratings are not guarantees. Results will vary depending on the user’s hearing device
and hearing loss. If your hearing device happens to be vulnerable to interference, you
may not be able to successfully use a phone that has been tested and rated as Hearing Aid
compatible. Trying the phone with your hearing device is the best way to evaluate it for
your personal needs. Should you experience interference when using your [insert phone
model here] with your hearing device, Sprint suggests you promptly return the phone to
the store. With the Sprint 14-day Risk-Free Guarantee you may return the phone within
14 days of purchase for a full refund. Sprint further suggests you experiment with
multiple phones (even those not labeled with an M3 or M4) while in the retail store to
find the one that works best with your hearing device
Hearing devices may also be measured for immunity to this type of interference. Your
hearing aid device manufacturer or hearing health professional may help you find results
for your hearing device. The more immune your hearing aid is, the less likely you are to
experience interference noise from wireless phones.
