How do I link two Jabra Speak2 75 speakerphones?

Prerequisites

• Jabra Speak2 75 - firmware version 2.46.0

If two Speak2 75 speakerphones are within a 50cm/19.6in range of each other, the Smart button will be visible. To permanently link the audio between them, press the Smart button on both speakerphones. The link is permanent until you either unlink or perform a reset of the speakerphones.

To unlink the speakerphones, press and hold (8 seconds) the Smart button on one of the speakerphones.

Note
If two Bluetooth devices are connected to the Speak2 75, the last connected Bluetooth device will be replaced by the temporary link.
