Disassemble the KLN 94 to allow a small Philips-head screwdriver to access the
contrast adjustment Variable Resistor. This Variable Resistor is labeled “VR1”,
and is located near the bottom center on the printed circuit card of the 043-05012-
01 LCD Color Display. Easy access will require either the removal of the KLN 94’s
top cover, or an extender for the J5007 and J5009 Main Board connectors. It is not
necessary to extend J5001.
Next, plug the unit’s connectors back together and re-apply power to the KLN 94.
Go to the TST 11 page and set the contrast value to 128 as outlined in Paragraph
B. Rotate VR1 until the point of best contrast is obtained (as defined in Paragraph
C). Re-assemble the KLN 94 and repeat the contrast alignment as outlined in
