An adjustable potentiometer (2K ohm) is mounted at location R48. This allows pre-
emphasis to be adjusted (only if JP1 has a jumper to VCC). Use a number 1.4mm
jewelers screwdriver to adjust R48. Turning clockwise will increase the pre-emphasis
value. Turning counterclockwise will decrease the pre-emphasis value. R48 should
be adjusted to reduce overshoot. If no jumper is used, the pre-emphasis value will be
0.7V.
See Tx Features and Explanations (Page 6) - Pre-Emphasis for description of feature.
