Technical information
The hearing aid contains two radio technologies,
which are described below:
The hearing aid contains a radio transceiver using
short range magnetic induction technology working
at 3.84 MHz. The magnetic field strength of the
transmitter is very weak and is always below
–40 dBμA/m at 10 meter distance.
The hearing aid also contains a radio transceiver
using Bluetooth
®
Low Energy (BLE) and a proprietary
short range radio technology both working at
2.4 GHz. The 2.4 GHz radio transmitter is weak and
is always below 4 dBm e.i.r.p. in total radiated
power.
The hearing aid complies with international
standards concerning electromagnetic compatibility
and human exposure.
Due to the limited space available on the hearing aid,
relevant approval markings can be found in this
document.
