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 15 nW
(typically –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
shortrange radio technology, both working at
2.4 GHz. The radio transmitter is weak and is always
below 3 mW and equal to 4.8 dBm 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
booklet.
Additional information can be found in the
