Potentiometers at default settings
If using long cables , follow these steps:
a . Supply the Color Bars test signal to the input.
(Recommendation: Use an Extron VTG 300 Video Test
Generator to generate the test signal.)
b . Adjust the Gain pot for output 1 until the signal level at
the far end is the same as the input (or the display shows
the correct brightness and contrast).
c . Adjust the EQ pot for output 1 so that no overshoot or
round front corner appears at the far end on the scope (or
you see a sharp picture with no smearing).
d . Repeat steps 2 and 3 for the rest of the outputs.
