Wireless control dial does not work

If your Z407 control dial doesn’t work, try the following:

• Unplug the speakers. After ten seconds, plug in the speaker and make sure you hear the power-on tone.
• Reinstall the batteries and make sure that the LED turns solid, which indicates that your dial has reconnected to the speaker successfully.
• If it’s still not working, the battery charge could be low. Try replacing them with fresh batteries. The dial should reconnect to the speaker automatically.
• Reset all speaker settings. See Restore the Z407 speakers to default factory settings.

If the above steps did not help, you may need to purchase a replacement wireless control dial. Please keep in mind that you cannot connect two dials to one speaker set at the same time.
