I don't have a scanner (I should!), but will mail a photocopy if you email your mailing address.
For now, be advised that Audio Alchemy suggests you insert the 1/8" mini-plug into the unit BEFORE connecting the power supply to A/C. (I imagine to save the microprocessors from electro-shock therapy.)
To change modes, depress and hold the "Phase" button. The three "Power" LEDs will go off, then come on indicating the current mode. With the "Phase" button still depressed, press the "Input" button to sequentially select the desired mode. Reading the "Power" LEDs from top to bottom, (with 0=off and 1=on) the modes are: HDCD=000, 16=001, 18=010, 20=011, 22=100, 24=101, None=110. In HDCD mode, the "Phase" switch is disabled and both "Phase" indicators are on. Note that the "HDCD" and "None" settings are different: "HDCD" mode applies no resolution enhancement or dithering to a fixed output word length, while "None" performs resolution enhancement but does not dither to a fixed output word length. (This is described in an article by Robert Harley).
I hope this is a help.
