Your speaker array and Acoustimass module are paired at the factory. However, should you ever need to pair them for any reason, follow these steps:
Unplug the Acoustimass module AC power cord
Remove the door on the end of the speaker array
Press and hold the ADAPTiQ® button for 3-4 seconds until the status indicator starts slowly blinking orange
Plug the Acoustimass module AC power cord in the AC outlet
Pairing is complete when the Acoustimass module status indicator becomes solid orange and the speaker array status indicator (orange) turns off.
