    4. Check the control box installation condition and wireless environment:
      • If a device that generates electromagnetic radiation is nearby, such as a wireless LAN device or microwave oven, move the speaker system away from that device.
      • Turn off any other wireless LAN devices that are not in use to reduce the interference, and then check to see if the issue is resolved. 
        Note: If the issue is resolved, change the network connection of the peripheral device from wireless LAN to wired LAN, if possible.
      • The control box and speakers are installed too far away from each other. Bring them closer together.
      • If there is any obstacle between the control box and speakers, remove or move the control box and speakers away from the obstacle.
      • Do not install the control box too far back on a shelf. Install the control box in or on a shelf so that the front panel display is not hidden.
      • Move the control box, change the direction of the control box, or install the control box far away from a TV.
      • Interference between the network connection and speaker connection may occur. Try one of the following:
        • Change the wireless LAN connection of the control box and the router to a wired LAN connection.
        • Switch the band of the wireless LAN router to 2.4 GHz, then set up the wireless network connection between the speaker system and the wireless LAN router again using a 2.4 GHz band.
    5. Reset the speaker system.
