(2) The audio signal from the J-3514/U J1 pin K (MONITOR OUT) is
applied through the CX-7058/VRC to the AM-1780 J510 pin K. Within the AM-
1780 the audio signal is applied to J504, J505, J506, and J507, pins L.
Then the audio signal is applied through each CX-4723 pin L to the
respective C-2298. When the MONITOR switch of the C-2298 is set to ALL, the
R-442 and RT received signals can be monitored (Figure 96. Issued as
adjunctive material.). (Trace these circuits on your system diagram.)
