Section 8A: Important Safety Information 417
Safety
to those of phones. Ask your hearing health-care professional for the rating of your hearing
aid. Add the rating of your hearing aid and your phone to determine probable usability:
䢇Any combined rating equal to or greater than six offers the best use.
䢇Any combined rating equal to five is considered normal use.
䢇Any combined rating equal to four is considered usable.
Thus, if you pair an M3 hearing aid with an M3 phone, you will have a combined rating of six
for “best use.” This is synonymous for T ratings.
Palm further suggest that you experiment with multiple phones (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. If 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 Palm 30-day
Risk-Free Guarantee, you may return the device within 30 days of purchase for a full refund,
and you will only be responsible for charges based on your actual usage.
Getting the Best Hearing Device Experience With Your Device
