Display Adjustment
On the rear side of the SIO2USB-Interface two openings are installed. Behind
them two potentiometers for adjustment of the display brightness and contrast
can be found. The hole on the left side near the USB plug is for contrast ad-
justment, the hole on the right side near the SIO cable is for brightness ad-
justment.
To adjust contrast and brightness carefully slide in a screw driver in size
1.8mm or 2.5mm and turn it until the blade fits to the potentiometer.
Turning the screw driver counter clockwise reduces brightness and contrast,
turning the screw driver clockwise increases brightness and contrast. Setting
the potentiometers to the middle position should normally give good readability
of the display.
