Operation
Some hearing aid users have reported a buzzing
sound in their hearing aids when they are using cell
phones, indicating that the cell phone and hearing
aid may not be compatible. According to the ANSI
C63.19 standard (ANSI C63.19-2006 American
National Standard Methods of Measurement of
Compatibility Between Wireless Communications
Devices and Hearing Aids), 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.
For example, the sum of a hearing aid rating of 2
(M2/T2) and a telephone rating of 3 (M3/T3) would
result in a combined rating of 5. Any combined
rating that equals at least 5 would provide “normal
use”; a combined rating of 6 or greater would
indicate “excellent performance.”
The immunity of this hearing aid is at least M2/
T2. The equipment performance measurements,
categories and system classifications are based
upon the best information available but cannot
guarantee that all users will be satisfied.
NOTE: The performance of individual hearing aids
may vary with individual cell phones. Therefore,
please try this hearing aid with your cell phone
