“T” Rating: Phones rated T3 or T4 meet FCC requirements and are likely to be more usable with a hearing aid's telecoil (“T Switch” or “Telephone Switch”) than unrated phones. (T4 is the “better” or higher of the two ratings.) On those models with a telecoil mode setting, this rating is determined only with the phone so set. For setting instructions, see “Features for the Hearing Impaired” in the section entitled “Advanced Calling Features”. Note that not all hearing aids have telecoils in them.
Hearing aids may also be measured for immunity to interference from wireless phones and may have ratings similar to wireless 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 the estimated usability:
⬤Any combined rating equal to or greater than six offers excellent use.
⬤Any combined rating equal to five is considered normal use.
⬤Any combined rating equal to four is considered usable.
Thus, if you use an M3 phone with a M3 hearing aid you will have a combined rating of six for “excellent use.” This methodology applies equally for T ratings.
Should you experience interference or find the quality of service unsatisfactory after purchasing your phone, promptly return it to the store within 30 days of purchase. With the Sprint
