    Check the firmware version

    Do I need to download it? This update is not necessary if your DMP-Z1 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. Tap the [Options/Settings] icon, in the bottom right corner of the screen
    2. Select the [Settings] menu
    3. Scroll until the bottom and choose the [Unit Information] menu. 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.
      Note: 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.
