ZonePlayer(s) software updates
If a ZonePlayer’s software version gets out of sync from the rest of your Sonos Digital
Music System components, you will see the following message displayed in the Zones
pane:
Click Yes to begin the software update process.
Advanced Preferences
Upon occasion, it may become necessary to adjust some of the default settings for
your Sonos Digital Music System. The Advanced Preferences menu option allows you
to change the wireless channel your Sonos Digital Music System operates on, as well as
change the encoding method for line-in source devices you may connect to your
music system.
Selecting a different wireless channel
The Sonos Digital Music System selects the optimal radio frequency channel during
setup. However, if you have other wireless devices using this channel, you may want to
switch the Sonos Digital Music System to another channel to avoid conflicts, as
conflicts may cause audio drop-outs.
1. From the File menu, select Preferences.
2. Click the Advanced tab.
3. Select another wireless channel from the Wireless Channel list, and click OK.
Caution Do not disconnect power from your ZonePlayer(s), or in any way disable
your Sonos Digital Music System while this process is running. Contact Sonos
Customer Support if an error occurs.
One or more ZonePlayers may need to be
updated if you purchase a new ZonePlayer with
a later software version, or if you plug in a
ZonePlayer that was not in use when you
performed your last software update.
