For a hearing aid with both acoustic coupling and
telecoil coupling with a rating of M4/T2 and with a
telephone rating of M3/T3, the combined rating is 7
(M4 + M3) for the acoustic coupling and 5
(T2 + T3) for the telecoil coupling. According to the
guideline given above, both types of coupling will
thereby be acceptable, with the acoustic coupling
indicating excellent performance and the telecoil
coupling indicating normal use. The above equipment
performance measurements, categories and system
classifications are based upon the best information
available, but it cannot be guaranteed that all users
will be satisfied.
The immunity of all Bernafon hearing instrument
models covered by these instructions for use is at
least M2.
