Wiring the power cord
Step 4
Connect power cords to the input and the outputs, and turn on the
equipment.
Step 5
Adjust the potentiometers for the outputs, using an Extron Tweeker.
If using very short output cables, set all pots to the default
setting (the arrow on the pot pointing to the dot beside it; see
illustration below).

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.
