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.
