For example, the sum of a hearing aid with a rating
of 2 (M2/T2) and a telephone with a rating of 3 (M3/
T3) would result in a combined rating of 5. According
to the standard, 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 all Bernafon hearing instrument
models covered by these instructions for use is at
least M2/T2. The equipment performance mea-
surements, categories and system classications
are based upon the best information available but
Bernafon cannot guarantee that all users will be
satised.
