1.) We changed resistor number 107 on the display board from 10K to 3.0K to allow the contrast to work without resetting the
computer.
2.). Put in a contrast adjustment for the display. While turning the control power on, hold in on the screens key, and this will enter
the contrast adjustment mode. Now use the UP/DOWN arrow keys to adjust. If the screen is solid black press the down arrow
key, if nothing appears on the screen press the up arrow keys. NOTE: You cannot hold in on the UP/DOWN arrow keys to
adjust, you must continue to press and then release them or nothing will happen.
3.) Put Software in for 3 rd Fan and Heater.
