5.4.1 PCB Removal and Replacement

Estimated Time to Repair:

⁄

hour

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. 5-4

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.
