FM system
An FM system is a radio communication system in
which a transmitter sends signals to a receiver via carri-
er waves. ”FM” stands for “frequency modulation” and
is a technical term for the way in which the radio signal
is produced. FM transmission ensures high quality re-
ception without any noise, hum or distortion.
If you have two hearing aids, they should both have a
receiver.
hibernation mode
If the receiver receives no signal from the transmitter, it
will automatically switch to hibernation mode, reducing
power consumption significantly. The receiver “wakes
up” automatically after a maximum period of 20 sec-
onds after a transmitting signal is received.
Interference
Interference occurs when signals from two transmitters
on the same frequency are mixed in the same receiver.
When the signals are equally strong, the interference
will be most noticeable. The further away one transmit-
ter is from the receiver compared to the other transmit-
ter, the weaker the disturbing noise will be.
Interference can be avoided by selecting another trans-
mitting and receiving channel.
