108 Safety and Warranty Information: Important Safety Information
Some hearing devices are more immune than others to this interference noise, and devices also vary in
the amount of interference noise they may generate. ANSI standard C63.19 was developed to provide a
standardized means of measuring both wireless device and hearing devices to determine usability rating
categories for both.
Ratings have been developed for mobile devices to assist hearing device users find devices that may be
compatible with their hearing device. Not all devices have been rated for compatibility with hearing
devices. Devices that have been rated have a label located on the box.
Your Instinct (SPH-M800) has an
M3 and T3 rating .
These ratings are not guarantees. Results will vary depending on the user’s hearing device and individual
type and degree of hearing loss. If a hearing device is particularly vulnerable to interference noise, even a
device with a higher rating may still cause unacceptable noise levels in the hearing device. Trying out the
device with your hearing device is the best way to evaluate it for your personal needs.
M-Ratings: Devices rated M3 or M4 meet FCC requirements for hearing aid compatibility and are likely to
generate less interference to hearing devices than unrated devices. (M4 is the better/higher of the two
ratings.)
T-Ratings: 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 devices. (T4 is the better/higher
of the two ratings. Note that not all hearing devices have telecoils in them.)
Hearing aid devices may also be measured for immunity to interference noise from wireless devices and
should have ratings similar to devices. Ask your hearing healthcare professional for the rating of your
hearing aid. Add the rating of your hearing aid and your device to determine probable usability:
ⅷ Any combined rating equal to or greater than six offers excellent use.
ⅷ Any combined rating equal to five is considered normal use.
ⅷ Any combined rating equal to four is considered usable.
Thus, if you pair an M3 hearing aid with an M3 device, you will have a combined rating of six for “excellent
use.” This is synonymous for T ratings.
Sprint further suggests you experiment with multiple devices (even those not labeled M3/T3 or M4/T4)
while in the store to find the one that works best with your hearing aid device. Should you experience
interference or find the quality of service unsatisfactory after purchasing your device, promptly return it to
the store within 30 days of purchase. With the Sprint 30-day Risk-Free Guarantee, you may return the
device within 30 days of purchase for a full refund. More information about hearing aid compatibility may
be found at: www.fcc.gov, www.fda.gov, and www.accesswireless.org.
