Interference
• Your hearing instrument has been
thoroughly tested for interference,
according to the most stringent
international standards. However,
interference with your hearing
instrument and other devices may
occur, (e.g., some mobile telephones,
citizens band systems and shop
alarm systems). If this occurs,
increase the distance between the
hearing instrument and the device.
Warning to hearing instrument
dispensers
A hearing instrument dispenser
should advise a prospective
hearing instrument user to consult
immediately with a licensed physician
(preferably an ear specialist) before
dispensing a hearing instrument if
the hearing instrument dispenser
determines through inquiry, actual
observation, or review of any other
available information concerning the
prospective user, that the prospective
user has any of the following
conditions:
(i) Visible congenital or traumatic
deformity of the ear.
(ii) History of active drainage from
the ear within the previous 90
days.
