Firmware Version

This simply ensures you are aware if you have the latest update or not. In some cases if you report
problems to the Matrix Audio technical support team, they may ask you which firmware version your
Delta Controller currently has. This often assists them in pinpointing your problem if it is related to the
Delta firmware and not to the installation or external wiring.
Once you press OK, you will return to the Main menu screen.
