Extron electronic QSD 204 D manual Input Reset, System Reset, Executive Mode

Input Reset

Each input of the QSD 204 decoder can be reset to its default centering values by holding down the specific input button until the Input # Reset message is displayed on the LCD screen.

System Reset

The QSD 204 can be reset to all of it’s default values by holding down the Input 1 button while simultaneously plugging in the power cord. The System Reset message will be displayed on the LCD screen.

Executive Mode

To prevent accidental changes to settings, press the Col/Tnt and Center buttons simultaneously for 2 seconds to enable the QSD 204’s Executive mode. Executive mode locks all front panel functions. The menu system will still return to the Default menu when 10 seconds have elapsed. The QSD 204’s front panel, but not the IR 901, is affected by Executive mode. The IR 901 will still be able to control the decoder after Executive mode has been enabled. When Executive mode is active, all functions and adjustments can still be made through RS-232 control. For details on RS-232 control, see chapter three.

To disable the Executive mode, press the Col/Tnt and Center buttons simultaneously for 2 seconds.
