If your original wireless control dial stopped working and you’ve purchased a replacement, you’ll need to connect the new dial to your Z407 speakers. Here’s how:

• Remove the batteries from the original wireless control dial to make sure that your speaker is disconnected from the original dial.
• Insert 2 AAA batteries in the new dial and then turn on your speaker.
• Long-press the wired input button and the Bluetooth button for eight seconds to activate initial pairing. The new dial will blink twice in blue and then turn solid after it connects to your Z407 speakers. You will hear a connected tone.
