Make sure that you always completely dry
your hearing aid after use. Store the hearing
aid in a safe, dry and clean place.
Special medical or dental examination
including radiation described below, may
adversely affect the correct functioning of
your hearing aids. Remove and keep them
outside the examination room/area before
undergoing:
•
Medical or dental examination with X-ray (also
CT scan).
•
Medical examinations with MRI/NMRI scans,
generating magnetic fields.
Hearing aids don’t need to be removed when
passing security gates (airports etc.). If X-ray is
used at all, it will be in very low doses, and will
not affect the hearing aids.
Mobile phone compatibility rating
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
classifications are based upon the best
information available but cannot guarantee
that all users will be satisfied. The immunity of
this hearing aid is at least M2/T2.
