Every so often we may need you to change the chip program on the board if we upgrade. This controls functions of the machine. This is how you do it.

YOU MUST REPLACE THE CHIP WITH THE SEMICIRCULAR INDENTS ON THE BASE AND THE IC CHIP LINED UP!! If you don't it may destroy the PCB board.

Note the correct way to remove an IC is with a special tool, but we will assume no one has this tool and it's not worth buying one.
