FM system
An FM system is a radio communication system in which a trans-
mitter sends signals to a receiver via carrier 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 reception 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 auto-
matically switch to hibernation mode, reducing power consump-
tion significantly. The receiver “wakes up” automatically after
a maximum period of 20 seconds after a transmitting signal is
received.
