Sonos component has stopped playing music
If a Sonos component stops playing music, and the status indicator lights are flashing (long amber, short white, repeat) this
indicates that the Sonos component has experienced a fault condition and has automatically muted itself to prevent damage
to the Sonos component.
• Check the Sonos component vents to ensure they are not blocked.
• Check for speaker short circuit.
• Unplug the Sonos component for several minutes to allow it to cool.
• Mute and unmute the Sonos component.
See "Player Status Indicators" on page A-7 for more information on LED lights.
Sound produced from only one speaker
• Make sure speaker is connected securely.
• Make sure balance control is set correctly.
Cannot access radio, online updates, or registration
• Your firewall may be blocking outgoing connections to the Internet. Ensure the firewall allows access to the Internet
for the Ethernet addresses of your Sonos components.
• Your firewall may be configured so that Sonos components cannot obtain an IP address. If so, your Sonos components
will display an IP address in the 169.254.xxx.yyy range, even though there is a router/DHCP server on the network. (You
can check the IP addresses assigned to your Sonos components by selecting About My Sonos System from the Set-
tings menu on a handheld controller, or About My Sonos System from the Help menu (PC) or Sonos menu (Mac) on
the Sonos Controller for Mac or PC.) The DHCP server built in to some routers may be configured to supply IP addresses
only to devices with specific permitted Ethernet MAC addresses. If you have configured your router in this way, you will
need to grant permission to the Ethernet MAC address of each Sonos component (including the Controller) before set-
ting up your system. For more information, go to http://faq.sonos.com/dhcp.
Controller screen is unresponsive
If the SONOS CONTROL's screen should ever become unresponsive, you can remove the battery from the back of the unit, and
then immediately put it back in. Place the controller into the charging cradle momentarily to wake it up.
Rooms do not display properly
If the Controller does not display your rooms properly, or displays the message, "Searching for Sonos components..."
• Make sure at least one Sonos component is plugged in and its status indicator is illuminated solid white.
• The Sonos component(s) may be going through an upgrade/restart, and rooms will reappear after the restart.
• Move the Controller closer to the Sonos unit.
