Maintenance:
After isolating the malfunctioning component, remove and replace the component. Most
components on the UDC / Transmitter Control Assembly mount directly to the mounting plate
with Philips head screws. The connections between the components are either semi-rigid or
coaxial connections. Either the power connectors are soldered to the component or utilize quick-
disconnects. Use the appropriate tool to make the repair. Use the Assembly Drawings and the
Schematics to determine placement.
Calibration:
See Paragraph 5.1.1, 5.1.2, 5.1.4, 5.4.1, 5.4.2, 5.4.3, and 5.4.4
