CHAPTER 6 PAGE 51
There are four major sub-assemblies that make-up the CWR6850:
1. The cabinet with its controls, connectors, and wire harnesses.
2. The CRT display section.
3. The digital circuit board (top board).
4. The modem circuit board (bottom board).
Most of the following adjustments are located on one of the two circuit boards. It is NOT neces-
sary to remove any circuit boards to make these adjustments. You will, however, have to remove
both the top and bottom covers of the CWR6850. Be careful to avoid misplacing any of the sixteen
black screws that fasten the covers in place - they are metric and not easily replaced! Use a good
No. 2 Phillips screw driver (NOT No. 1 or smaller). The diagrams in Figure 10 show the boards AS
VIEWED FROM THE FRONT PANEL.
