same channel as the 108 Mbps device (usually channel 6). While it is possible to put all of your wireless devices on channel 6, it
is unwise. The devices will have to compete for available bandwidth, and your entire wireless network will become sluggish.
4. Change the wireless channel your Sonos system is operating on
• Using the Sonos Controller for PC: From the File menu, select Preferences. Click the Advanced tab, and select another wire-
less channel from the Wireless Channel list.
• Using the Sonos Controller for Macintosh: From the Sonos menu, select Preferences. Click the Advanced tab, and select
another wireless channel from the Wireless Channel list.
• Using the Sonos Controller 200, touch Music Menu > Settings > Advanced Settings. Touch Wireless Channel and then
choose another wireless channel from the list.
It may take several seconds for the switch to take effect. If you have music playing, a short music dropout will occur during the
wireless channel change.

ZonePlayer isn't operating properly

• If the ZonePlayer status indicator is not lit and no sound is produced when the unit is plugged in, check the insertion of the
power cord.
• Check to ensure that the ZonePlayer Status indicator on the front of the ZonePlayer is illuminated and solid white. If it is
flashing or solid amber, see "ZonePlayer has stopped playing music" on page A-4.
• Check to ensure that the green link light is lit on the Ethernet switch on the rear panel of the ZonePlayer wired to your net-
work.
• Move the Controller closer to the unit.
• Check to ensure there are no obstacles to impede wireless operation.
• Check your network connections.
• The ZonePlayer may need to be reset. Disconnect the power cord for 5 seconds, and then reconnect. Wait for the ZonePlayer
to restart.
• If none of these work, the ZonePlayer may need to be factory reset. Disconnect power, and then reconnect the power plug
while pressing and holding the Mute button until the Mute indicator light begins to flash amber. Use a Sonos Controller to
add it to your Sonos system again. (This might be necessary if, for example, you've purchased a previously used ZonePlayer
from a friend.)
Important Note: You should not factory reset all of your ZonePlayers at once or your established
preferences and Sonos playlists will be lost.

ZonePlayer status indicator lit, but no sound

• Make sure speakers are connected securely.
• Make sure volume is set to a suitable level.
• Make sure MUTE is not on.

ZonePlayer volume level reduces

If the ZonePlayer status indicator changes to solid amber, and the volume reduces to 75%, this indicates that the ZonePlayer is
experiencing a fault condition.
• Check the ZonePlayer vents to ensure they are not blocked.
• Check for speaker short circuit.
• Mute ZonePlayer or unplug it for several minutes to allow it to cool.
