Frequently Asked Questions - LA90 Humantechnik

How to charge the LA90 battery?

Connect the provided power supply unit to the device. The charge indicator flashes red during charging and turns off when the battery is full (approx. 3 hours). You can use the device while charging, but this extends the charging time.

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 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.

Recording/ emitting signals

If sounds are received 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 selection 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 .

DIR under-the-chin receiver
- Unobtrusive earphones
- Lightweight headset

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.
