with the FDA regulations
Important information: Cell phones
Some hearing aid users have reported a buzzing sound
intheir hearing aids when they are using cell phones.
According to the ANSI 63.19 (American National Standard
Methods of Measurement of Compatibility between
Wireless Communications Devices and Hearing Instruments)
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 would indicate “excellent performance”.
Theequipment performance measurements, categories and
system classications are based upon the best information
available but cannot guarantee that all users will be
satised. The immunity of this hearing aid is at least M2/T2.
