Making a call via Bluetooth
1. With the Bluetooth connection enabled, dial a number from the Bluetooth device.
The call will be conducted using the FLX Speaker and Microphones.
Answering a call via Bluetooth
1. You can answer a Bluetooth call directly from your FLX system. If answering the
call with the FLX system it will automatically be in speaker mode.
2. If you answer the call using your Bluetooth device, settings on that device will
determine whether the call will be answered as a speaker call using the FLX
Conference Phone, or as a call using other audio devices. If you want to have a
private call not using the FLX as the Speaker of the call, ensure that you select
the correct audio output device in your Bluetooth enabled device.
Video Conference Collaboration
The FLX2 System is equipped with balanced analog audio input and output to be
connected to 3
rd
party video or PC conferencing system. This allows the FLX
Microphones and Speaker to be used as Microphones and Speaker for the video call. It
also provides Acoustic Echo Cancelation and Noise Control to the video call.
Connecting a Video Conference System
In the advanced audio setting (see page 38), change the Aux Audio setting for Aux Out
to MIC. Then connect one of the AUX OUT on the FLX2 Base Station via an
appropriate mono balanced or unbalanced cable with 3.5mm plugs to the ‘Mic Input’ on
the video conference system.
The line level audio AUX IN on the FLX2 Base Station should be connected, via the
appropriate mono balanced or unbalanced 3.5mm cable, to the ‘line output’ of the video
conference system.
As the FLX system provides the Echo Cancelation for the call, any Echo Canceler in the
Video Conferencing unit needs to be switched off. Not switching off the Echo Canceler
in the Video Conferencing unit will negatively affect the audio on the FLX Speaker and
Microphones. Please visit the documentation of your video conferencing unit on how to
disable the Echo Canceler.
Any audio device like external speaker or TV speaker attached to the video
conferencing unit needs to be disabled. The FLX Speaker and Microphones become
your only audio devices for the Video Conferencing call. Any other devices will affect
the Echo Canceler and will cause negative impact on the audio of the call.
For security reasons the FLX Microphones will not send any audio to the AUX OUT
while in the Charger Base. The microphones have to be removed from the Charger
Base to send audio data to the AUX OUT connector.
Configuring the Analog Audio
For best audio results, the AUX IN and AUX OUT connectors have to be configured in
the right way to receive best results with your video conferencing unit. This requires
testing and setting of the values in your environment. See page 35 on how to set the
