Cell phone
Some hearing aid users have reported a buzzing sound in their
hearing aids when they are using cell phones. According to the ANSI
C63.19 standard, the compatibility of a particular hearing aid and
cell phone can be predicted by adding the rating for the hearing aid
immunity to the rating for the cell phone emissions. The sum of the
hearing aid rating (e.g. M2/T2 = 2) and the telephone rating (e.g. M3/
T3 = 3) is 5, and any combination that equals 5 will provide ‘normal
use’. A sum of 6 or greater indicates ‘excellent performance’. The
equipment performance, measurements, categories and system
classifications are based upon the best information available but
cannot guarantee that all users will be satisfied.
The rating of this hearing aid is at least M2/T2. Your hearing
healthcare professional can provide the actual rating for this
hearing aid.
Note: the performance of the individual hearing aids may vary
with individual cell phones. Therefore, please try the hearing aid with
your cell phone or, if you are purchasing a new phone, please be
sure to try it with your hearing aid prior to purchase. For additional
guidance, please ask your hearing healthcare professional for the
booklet entitled “Hearing aid compatibility with digital wireless cell
phones”.
