5.4.1 PCB Removal and Replacement

Estimated Time to Repair:
The microprocessor PCB assembly is protected by a cover
fastened to the rotating plate – Fig. 5-1. The cover must be
removed to gain access to the main power fuse and the PCB
assembly.
1. Using needle-nose pliers, remove the E-ring from
one end of the connecting rod – Fig. 5-2.
2. Remove the connecting rod by sliding it off the
bracket.
3. Fully retract the elevation axis motor shaft
– Fig. 5-5.

Maintenance
When carrying out maintenance
on the PCB, be sure to not drop
any of the small screws inside the
mechanism. If a screw is lost within
the baseplate, it must be retrieved
to avoid causing any damage when
the unit rotates.
