The speakerphone can save up to eight paired Bluetooth
devices. If you pair the speakerphone with a ninth
Bluetooth device, the saved connection profile of the least
recently used device will be overwritten. If you want to
re-establish a connection with this device, you have to pair
the speakerphone again.
The speakerphone can be wirelessly connected to two
devices at the same time.
You can only connect another device by disconnecting
one of the already connected devices.
The speakerphone can be used wirelessly with a computer.
