Microphones in the Charger Base has to be activated manually
by pressing the Microphone button before switching from the
handset call to a speaker call.
Telephone Call
The FLX2 Conference Phone allows making conference calls using an analog
telephone connection. A telephone call can be made using either 'speaker mode' or
'handset mode'. A telephone call can be made at the same time as a video call.
Telephone calls are controlled via the FLX Dialer.
Bluetooth Call
The FLX2 System is equipped with a Bluetooth interface that supports the Hands Free
Profile (HFP). This profile allows the user to make a call through a cell phone, a
computer, or other device via a Bluetooth connection. A Bluetooth call can be made
using 'speaker mode' only. A Bluetooth call is controlled by the connected Bluetooth
device. A Bluetooth call can be made at the same time as a video call.
NOTE: Revolabs FLX only supports the Hands Free Profile
(HFP) for Bluetooth 2.0 or higher. Applications that try to use
the Bluetooth connection not using the HFP profile, or that are
using an older HFP / Bluetooth standard are not supported by
the FLX.
Video Conference Call
rd
The FLX2 System can be connected to a 3 party video or PC conferencing system via
the Analog I/O ports located on the FLX2 Base Station. This allows the Microphones
and Speaker to be used as the audio interface for the video conference call. Video
Conference calls are controlled primarily by the video conference system. However,
audio properties can be controlled via the FLX Dialer. While the FLX2 Conference
Phone is connected to a video conferencing device, it might still make and accept calls
over the analog telephone connection or via a Bluetooth device.
NOTE: When using the FLX connected through the AUX IN
and AUX OUT to another device, only the FLX speaker can be
used. All other speakers, e.g. in a television set, must be turned
off. To avoid audio problems, any Echo Cancellation provided
on the Video Conferencing unit should be switched off.
NOTE: For security reasons, Microphones will not send any
audio signal to the AUX OUT connector when in the charger.
To receive audio signal on the AUX OUT, microphones have to
be taken out of the Charger Base.
