components.
• Your firewall may be configured so that Sonos components cannot obtain an IP
address. If so, your ZonePlayers and Controllers will display an IP address in the
169.254.xxx.yyy range, even though there is a router/DHCP server on the net-
work. (You can check the IP addresses assigned to your ZonePlayers by selecting
Music>System Settings>About Your Digital Music System.) The DHCP serv-
er built in to some routers may be configured to supply IP addresses only to de-
vices 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 setting up
your system. Go to http://faq.sonos.com/dhcp for more information.
There’s a delay when I play music from an external music source
If Compressed is selected as the encoding method for your line-in music source, you
will notice a delay before the music starts to play. When Uncompressed is selected,
this delay is significantly reduced.
Controller screen is frozen
If your Controller’s screen should freeze, press and hold the Mute and Music buttons
simultaneously on the Controller for approximately 3 seconds. The Controller will reset
itself momentarily.
Zones do not display properly
If the Controller does not display your zones properly, or displays the message,
“Searching for ZonePlayers...”
• Make sure at least one ZonePlayer is plugged in and its status indicator is illumi-
nated solid white.
• The ZonePlayer(s) may be going through an upgrade/restart, and zones will re-
appear after the restart.
• Move the Controller closer to the ZonePlayer.
• Your Controller may be configured to work with a different Sonos Digital Music
System. Disconnect the Controller from the Sonos Digital Music System, and
then re-add it.
