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 difficult 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.
As an alternative, you may use an audio streaming
device (accessory) with a plug for FM receivers.
Consult your Hearing Care Professional for further
information.
■
Ask your Hearing Care Professional to configure your
hearing instruments, for example:
□
Adjust the mix of the audio input signal with
surrounding sounds.
□
Configure the controls so that you can select
between audio input signal only, surrounding sound
only, or a mix of both signals.
Audio induction loops
Some telephones and public places like theatres offer the
audio signal (music and speech) via an audio induction
loop. With this system, your hearing instruments can
directly receive the desired signal – without distracting
noise in the environment.
You can usually recognize audio induction
loop systems by certain signs.
Whether a telecoil is built into your hearing instrument is
listed in section "Settings". If a telecoil is built in, you have
the following options.
Ask your Hearing Care Professional to configure a telecoil
program.
X
Switch to the telecoil program whenever you are in a
place with an audio induction loop.
If a telecoil program is configured for your hearing
instruments, it is listed in section "Settings".
Telecoil program and remote control
NOTICE
For instruments with wireless connectivity:
When the telecoil program is active, the remote
control may cause a pulsing noise.
X
Use the remote control with a distance greater
than 10 cm (4 inches).
