Test Pattern for HF Gain and Skew adjustments
Select the video channel that you are going to adjust (A or B).
Start by adjusting HF gain (hit Select button as needed to light all 3 LED’s on the
Receiver). It is best to start at the min compensation setting. To do this either press the
Down button repeatedly until the LED’s blink (indicates you are at min), or simply press
both Up and Down buttons simultaneously.
If the UTP cable is long then the black and white horizontal lines tend to appear smeared

paying particular attention just to the right of the horizontal lines. Your goal is to make the
transition between the horizontal black and white lines and the grey background to have
as little smear as possible. Do not over adjust. If you do, some smear comes back
particularly near the transition but in reverse sense (white lines smear as black and vice
versa). The following images depict the adjustment results as seen on the screen:
