Linked Mode

Two conference phone Sound Base units can be linked together to expand the audio coverage area. One Sound
Base acts as the primary device, and the other unit acts as the dependant or secondary device.
In Linked Mode, the primary base station supports either one wireless or one wired microphone. The secondary
unit supports only one wired microphone. You cannot mix microphone kits: if you plan to connect a microphone
to both sound bases, they must both be wired microphones.
The voice, dial tone, ringer, and base LED features synchronize between the two devices when linked together.
You can link two sound bases while a call is active.
When Linked Mode is active, the linked mode icon displays in the idle and the call screens.
The following table summarizes the best practice to follow when deploying your conference phones in Linked
Mode. If the devices are linked in this manner, the system software automatically detects which device is to
be used as the primary and which is the secondary one.
