324 Section 5A: Safety
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 Treo 650 has an M3 rating.
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 Treo 650 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
.
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.
