+**X** & **Y** values range between ''0 and 100''.  Y determines amplitude of the video signal entering the system.  Setting a 0 value attenuates a video signal completely, while a setting of 100 lets the full signal go through.  Attenuating a video signal also reduces the noise in the signal.  If the focus value on the LCD reads ''2047'', then the system is saturated with too much signal, try reducing the **Y** value.
+**X** is the zeroing potentiometer; the value of X should be set such that, when **Y** is ''0'', the //focus value// is also ''0000'' (or as close as possible).
+**Z** sets the gain of the final Analog to Digital Converter (ADC) in the auto-focus system.  Range:  ''0 to 3''.  By adjusting this setting, a //focus value// for a sparse sample can be magnified to get better focus.  If an incorrect value of gain is used, the ADC saturates and the focus value reaches ''2047''.  Upon system restart, the setting returns to its default value of 0.  Perform an [[commands:saveset|SS Z command]] to save the current gain setting in non-volatile memory.
