Your phone is compliant with FCC HAC regulations (ANSI C63.19- 2011). While 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  a rating  system  for  wireless 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 have the rating on their box or a label located on 
the box. 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 use a rated phone successfully. Trying out the phone with your hearing device is the best 
way to evaluate it for your personal needs. 
This  phone  has  been  tested  and  rated  for  use  with  hearing  aids  for  some  of  the  wireless 
technologies that it uses. However, there may be some newer wireless technologies used in this 
phone that have not been tested yet for use with hearing aids. It is important to try the different 
features of this phone thoroughly and in different locations, using your hearing aid or cochlear 
implant,  to  determine  if  you  hear  any  interfering  noise.  Consult  your  service  provider  or  the 
manufacturer of this phone for information  on hearing  aid compatibility.  If you have questions 
about return or exchange policies, consult your service provider or phone retailer. 
M-Ratings:   
Phones rated M3 or M4 meet FCC requirements and are likely to generate less interference to 
hearing devices than phones that are not labeled. M4 is the better/higher of the two ratings.   
T-Ratings: Phones 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 phones. T4 is the better/ 
higher of the two ratings. (Note that not all hearing devices have telecoils in them.)   
Your phone meets the M4/T3 level rating. Hearing devices may also be rated. Your hearing device 
manufacturer or hearing health professional may help you find this rating. For more information
