TO HELP YOU ASSEMBLE THE MAIN BOARD, THE THREE SWITCHES ARE ALREADY MOUNTED
ON THE BOARD THEY JUST HAVE TO BE SOLDERED.  THE TWO JACKS ARE ALSO ALREADY
MOUNTED.  THE PREPOSITIONING IS DONE TO ELIMINATE ANY PROBLEM IN THE
MECHANICAL ALIGNMENT OF THE SWITCHES AND JACKS WITH THE FRONT PANEL.  A FEW
MORE HINTS A LITTLE PRESSURE IS NEEDED TO MOUNT THE VOLTAGE REGULATOR CHIP.
WHEN TESTING THE CHIP OPERATION, GROUND IS THE MIDDLE PIN AND THE 5 V
OUTPUT IS THE PIN NEAREST THE POTENTIOMETER.  ALTHOUGH THE COLOR
ILLUSTRATIONS ARE QUITE CLEAR, DOUBLE CHECK THAT PIN 1 OF THE INTEGRATED
CIRCUIT IS NEAREST THE SMALL PRINTED SQUARE ON THE BOARD.  FIGURE 11 SHOWS
THE MAIN BOARD MOUNTED IN THE BACK HALF OF THE CASE, WITH THE DISPLAY BOARD
AND TWO CABLES ON THE TOP OF THE FIGURE.  NOTE THAT THE WIRES ARE INSERTED
INTO THE BACK OF THE DISPLAY MODULE.  PAY ATTENTION TO THE SOLDER PAD
NUMBERING 1, 3, 5, AND SO ON ARE IN ONE ROW, AND 2, 4, 6, AND THE OTHER
EVEN NUMBERS IN THE OPPOSING ROW.  PLACING THE MAIN BOARD IN THE CASE, THE
FOUR PIN PLUG HAS TO BE BENT UP SLIGHTLY TO GET THE NUT UNDER IT ON.  I
FOUND IT EASIEST TO USE THE KIT NUT DRIVER WITH A SMALL AMOUNT OF MODELING
CLAY TO HOLD THE NUTS IN POSITION TO START THEM ON THE MOUNTING SCREWS.
THE ASSEMBLY MANUAL INCLUDES A PAGE OF CALIBRATION INSTRUCTIONS AND A SMALL
JUMPER.  THE UNIT TESTED HERE DID NOT NEED ANY FURTHER CALIBRATION.  IF
