    Preparation

    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 1.02 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
      5. Confirm the Model number and Firmware version

    Before you upgrade

    • Be sure to remain connected 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.
      We cannot guarantee tracks and data will not be damaged or deleted when performing this update.
    • When upgrading, the unit needs to have free space of about 200 MB. Please confirm the amount of free space is sufficient.
    • 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.
    • During the installation of this file, be sure that you are logged in as the Administrator or as a user with Administrative rights.

    Download & Install

    Step 1: Install the update

    1. Read and agree to the terms and conditions.
    2. Download the file to your computer.
    3. After completion of the download, connect your Walkman to your computer by USB connection.
    4. Quit all software running on your computer
    5. Double click the saved file and follow the on-screen instructions.
      Please do not disconnect the unit from the computer during the upgrade.
      Note for macOS 10.15 users: When you start the update tool the first time on macOS 10.15, a ["Software Update Tool" would like to access files on a removable volume] message is shown. If you click [OK], the updating starts. If you click [Don’t Allow], an error will be displayed and the updating will fail.
    6. When the message indicating the upgrade is complete is displayed, click on [Finish].

    Step 2: Check the update was successful

    After the update, please confirm the new version has been installed successfully by following the steps in the [Check the firmware version] section.

    If the Firmware version shown is “1.02”, the upgrade was successful.
