5.1 Digit/Driver Printed Circuit Board

The PC-2002 uses a single printed circuit board (PCB) that contains all of the electronics
needed to make this system work: digit LEDs, control processors, power input connectors,
horn, and other components. All switches, power systems, and input/output terminations are
connected to the PCB.

As shown in Figure 8, the PCB is attached to the front panel of the display. Refer to Section

5.2 for instructions on accessing and replacing the PCB.
