Audio input (FM system)
With an audio input you can connect your hearing
instruments to an FM system. An FM system consists of a
transmitter and a receiver. It gathers speech at the voice
source (via a separate microphone) and transmits the
sound directly to the hearing instruments.
The signal is clearer and unaffected by poor room
acoustics. This can be useful for adults in difcult listening
situations and for children in classrooms.
Most FM systems allow for coupling with audio devices
like an MP3 player.
Notes:
■ The battery compartment with audio input is available
as an accessory only for certain instrument types.
Consult your Hearing Care Professional for further
information.
■ Ask your Hearing Care Professional to congure your
hearing instruments, for example:
□ Adjust the mix of the audio input signal with
surrounding sounds.
□ Congure the controls so that you can select
between audio input signal only, surrounding sound
only, or a mix of both signals.
