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 always below 15 nW
(typically below –40 dBμA/m
(–12.20 dBμA/ft) at 10 meter
(33 feet) distance).
The hearing aid also contains a radio
transceiver using Bluetooth Low
Energy (BLE) and a proprietary short-
range radio technology both working
at ISM band 2.4 GHz.
The radio transmitter is weak and
always below 3 mW equal to 4.8 dBm
in total radiated power.
The hearing aid complies with
international standards concerning
electromagnetic compatibility and
human exposure. Only use your
hearing aid in areas where wireless
transmission is permitted.
Due to the limited space available on
the hearing aid, relevant approval
markings can be found in this
document.
