How it works
The »LA-90« uses its built-in microphone or
an external microphone to record sounds
and emits them via the integrated induction
loop. The signals emitted in this way can be
received by a hearing aid that is set to the
"T" or "MT" position.
Setting up the »LA-90«
The induction loop system is already com-
pletely installed and set up in the housing.
All you have to do is to place the »LA-90«
at the desired position between you and
the person you are talking to and connect
the power supply unit. Please note that the
microphone on the back of the device should
be facing the speaker.
After you have placed the »LA-90« you can
10 English
mark the found position with the included po-
sition marker. This is useful if the device is
removed for the night.
Switching the device on
To switch the induction loop system on,
press the "Power on" button on the rear side
of the device. Once the device is switched
on, the "Power on" control light will light up
green and the control light on the front side
of the device will light up blue.
Recording/ emitting signals
If sounds are received by the microphone
on the back of the device or via an exter-
nal microphone and emitted by the device
as magnetic signals, the status light "loop
signal" will begin to flash orange.
Additional microphone input
(3.5 mm plug)
An external microphone can be connected
to the additional microphone input (e.g.
microphone cable A-4901-0).
Microphone selection switch
With the microphone selction switch you can
choose the microphone which should record
the sounds.
Switch position:
Up: internal microphone only
Middle: internal and external microphone
Down: external microphone only
Setting the sensitivity of the microphone
input
With the control dial on the backside of the
device you can adjust the sensitivity of the
microphone input. This is useful if you want
to connect a low-output microphone to the
»LA-90«.
