Menus, Configuration, and Adjustments

Decoder configuration and adjustments can be performed by using the Windows-based control program (see chapter 3 for details) or by using the front panel controls and the menus that are displayed on the QSD 204’s LCD screen. These menus are used primarily when the decoder is first set up.
