Chapter 7: The Sonos® Controller 7-13
This Controller will be unavailable for use until you perform a software update to bring
the Controller up to date. This situation will occur if you perform a software update
from another Controller, or from the Desktop Controller software.
ZonePlayer software updates
If a ZonePlayer’s software version gets out of sync from the rest of your Sonos Multi-
Room Music System components, you will see a message displayed on your Zones
menu.
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.
You will also see this out-of-date message if you have already updated your music
system using the Controller. This message will indicate that the Desktop Controller
software needs to be updated.
Press OK to begin the software update process.
