7.2 - firmware update
To perform a firmware update or to check the availability of a new firmware version, the d:series amplifier
has to be connected to the Internet. Please select the ‘system’-button on the left side of the touch display.
To perform the firmware update, the following steps have to be done:
1. Select the button ‘check for update’ at the bottom of the system screen
2. If a newer firmware version is available for the device, the button changes to ‘download update’.
Select the button to perform the downloading process.
3. Check the state of the download in the progress bar.
4. After the download select the ‘install now’-button for starting the update. Now a pop up window
appears for an additional confirmation of the update procedure. Please select ‘Yes’ to start the update
or ‘Cancel’ to abort.
5. During the update procedure and to reboot of the device, the screen turns white for a moment (not
more than one minute).
6. After the successful update a pop up window appears on the display which confirms the update and
also shows you the actual firmware version of your d:series amplifier.
Do never unplug the power supply of the amplifier during the updating process!
