Electromagnetic interference
Your hearing instrument has been thoroughly tested
for electromagnetic interference. However, some
products may emit electromagnetic energy causing
unforeseen interference with hearing instruments.
Examples include induction cooking appliances,
shop alarm systems, mobile phones, fax machines,
personal computers, X-rays, CT scans, etc.
Even though your hearing instruments are designed
to comply with the most stringent international
standards of electromagnetic compatibility, they
may emit electromagnetic energy that can cause
interference with other devices.
Your hearing instruments contain a radio transmitter
using short range magnetic induction technology
working at 3.84 MHz. The magnetic field strength
of the transmitter is < -42 dBμA /m @ 10 m.
