PCB Removal and Replacement
The printed circuit boards (PCBs) are protected by a cover
fastened to the antenna support frame. The cover must be
removed to gain access to the main power
fuses
and the
PCB assemblies discussed below. Refer to Figure 4-2; remove
3 nuts and washers from the bottom flange and 3 screws and
washers from the upper flange. Remove the cover and set aside
with the fasteners.
The CPU PCB has been changed from an “L”-shaped design to a
simpler straight design. Figure 4-3 has been updated to show the new
CPU PCB.
