Clock Frequency Adjustment

To perform the clock frequency adjustment, you must first remove the cabinet.
For removal and installation procedures for the cabinet, refer to Cabinet on
page 6-18.

After you have removed the cabinet, find the test point and adjustment pod on
the A10 Main board. See Figure 5-1.
