FYI: You will need an USB-Mouse (or the remote for the viewneo 4K SignageBox) to unregister your device.
To unregister your device and to receive a new activation key, follow these steps:
- Go to the player menu by clicking the locker icon in the upper right corner of your screen with the mouse or remote. The icon appears after clicking on your screen randomly twice. If you are using the remote you simply push the menu button to enter the player menu.
- Switch to "SYSTEM" and click "UNREGISTER" at the bottom.
- Afterwards you need to confirm your action. Your device will then be disconnected from your account and a new activation key will be shown. Furthermore the device should be deleted from your account.
