You can enjoy “Music Unlimited” by purchasing the “Music Unlimited” license (Basic or Premium)
on your computer. The “Music Unlimited” license has an expiry date depending on your contract.
This chapter will explain about the license when enjoying “Music Unlimited” on your Walkman.

Expiry date of your Walkman

The expiry date for using the “Music Unlimited” function on your Walkman depends on your plan
(Basic or Premium). (This is just the expiry date for using the “Music Unlimited” function on the
Walkman, which is different from the “Music Unlimited” license on your computer.)
Before expiry, you will need to connect your Walkman to your computer and access the server to
update the license. (As the expiry date nears, an alert message will be displayed, alerting you to
update the license.)
If the license is expired, you cannot use the “Music Unlimited” function. In this case, connect your
Walkman to your computer and access the server to update the license.

Note

If the license expires while listening to a song on “Music Unlimited,” an alert message
appears and your Walkman returns to the Home menu automatically when the current song
playback is finished, then the “Music Unlimited” function will not be available.

Expiration date of the “Music Unlimited” license on your computer

When the “Music Unlimited” license on your computer expires all contents of “Music Unlimited”
on your Walkman are deleted, and the “Music Unlimited” function cannot be used when
connecting the Walkman to your computer. (As the expiry date nears, an alert message will be
displayed.)

When you reset your Walkman

The license on your Walkman will not be deleted if you perform [Reset All Settings].
The license on the Walkman will be deleted if you perform [Format]. In this case, connect the
Walkman to your computer and transfer the “Music Unlimited” contents to the Walkman.
