    Before You Start

    Check the firmware version

    Do I need to download it? This update is not necessary if your Walkman has already been updated to firmware version 3.02 by the automatic firmware update function. If you're not sure, it's easy to check which version of firmware you have:

    1. Press and hold the Power button until the Home menu appears.
    2. Tap the [Options/Settings] icon, in the bottom right corner of the screen.
    3. Select the [Settings] menu.
    4. Scroll until the bottom and choose the [Unit Information] menu. Confirm the Model number and Firmware version.

    Before you upgrade

    • Be sure to connect to the network while updating.
    • After updating, the firmware cannot be reverted to an earlier version.
    • Please transfer all data from the unit to the computer, since data which remains on the unit may be lost when upgrading.
      Note: We cannot guarantee tracks and data will not be damaged or deleted when performing this update.

    • If there is not enough free space in the built-in flash memory, transfer any unnecessary data back to the computer to increase free space.
