of the transmitter is very weak and
always below 15nW (typically below

(–12.20dBμA/ft at a distance of 33feet).
The hearing aids also contain a radio
transceiver using Bluetooth Low Energy
and a proprietary, short range radio
technology both operating 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.
Only use your hearing aids in areas where
wireless transmission is permitted.
