How it works
The »LA-90« uses its built-in microphone or an external microphone to pick up 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 completely 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 mark the found position with the
included position 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.
Picking up/ emitting signals
If sounds are picked up by the microphone on the back of the device or via an
external 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
Down: external microphone
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«.
Headphone jack (3.5 mm plug)
You can connect the following products to the Headphone jack:
- DIR under-the-chin receiver
- Unobtrusive earphones
- Lightweight headset
- Audio-Cable monaural
- Audio-Cable binaural
- Induction Link monaural
- Induction Link binaural
Volume control
With the volume control you can set the volume of the headphone jack.
Automatic switch off
The »LA-90« will switch off automatically if no signal is received via the
internal or external microphone for a certain time (2 minutes).
Switching the device off
To switch the induction loop system off, press the “Power off” button on the
rear side of the device. The “Power on” control light goes off.
Power supply for the »LA-90«
The »LA-90« can be operated using the built-in rechargeable battery or the
power supply unit. If the battery is fully charged, the device can be used for
up to 6 hours. A depleted battery has to be recharged for approximately 3
hours until it reaches full capacity again. You can also use the »LA-90« while
it is being charged, but please note that this will lengthen the time required
to fully recharge the battery. The device can remain connected to the power
supply for as long as desired.
Charging control light
LED flashes red = Battery is in the process of being recharged
LED off = Battery is fully recharged
Permanent installation of the »LA-90«
The »LA-90« can be screw-fastened through the lateral holes to a tabletop or
other sur- faces. The holes are located under the side covers. Remove the
covers as shown in the picture below.
Press on the retaining clip and remove the cover.
Wall mounting
- Screw-in two screws (not included) 14.1 cm apart at the place you would like to mount the »LA-90« on the wall (see figure).
- Now set the »LA-90« on the screws and slide it down slightly to secure it in place.
Rechargeable battery replacement if necessary
Changing the colour signal strip
You can change the colour signal strip of the »LA-90«.

The »LA-90« does not require any maintenance. If the unit becomes dirty,
simply wipe it clean with a soft, damp cloth. Never use spirits, thinners, or
other organic solvents. Do not set up the unit where it will be exposed to
