Product Approval, Markings and
Compliance
All Bernafon hearing aid models covered by these
instructions for use comply with international
standards concerning electromagnetic compatibility.
Due to the limited size available on the hearing aid,
all relevant approval markings are found in this
document.
Electromagnetic Interference
Your hearing aid has been thoroughly tested for
electromagnetic interference. However, some
products may emit electromagnetic energy causing
unforeseen interference with hearing aids. Examples
include induction cooking appliances, shop alarm
systems, mobile phones, fax machines, personal
computers, X-rays, CT scans, etc.
40
Even though your hearing aid is designed to comply
with the most stringent international standards
of electromagnetic compatibility, it may emit
electromagnetic energy that can cause interference
with other devices.
Your hearing aid contains a radio transmitter using
short range magnetic induction technology working
at 3.84 MHz.
The magnetic eld strength of the transmitter
is < – 42 dBμA/m @ 10 m.
The electromagnetic emission from the radio system
is well below international limits for human exposure.
By comparison, the electromagnetic energy of
the hearing aid is lower than that generated by
household items such as halogen lamps, computer
monitors, dishwashers etc.
