Do the output level adjustment as follows:
(a) Set the VMU tuner for reception of CH2 and make sure that the
oscilloscope shows a video signal waveform as shown in Figure
103N.
(b) Turn A8VR501 and adjust the amplitude of the video signal shown
on the oscilloscope to 0.8 Vp-p.

8. Wiring and Schematic Diagrams
A. The wiring and schematic diagrams are given as shown in the table below.
The EFFECTIVITY column shows the part numbers to which the diagram
applies. MOD numbers, serial numbers and/or other identification are
also shown as necessary to identify the applicability of the diagrams.

NOTE: The schematic diagrams of the A6 and A7 cards are included in the
wiring diagram (Figures 104 thru 104B).
B. Revision Reference Sheet
A revision reference sheet is included in front of each wiring or
schematic diagram. This sheet contains a descriptive history of changes
made to the equipment that have an effect on the wiring or schematic
diagram.
The EFFECTIVITY column of the sheet identifies when the change became
effective with the part numbers, MOD numbers, serial numbers and/or other
identification. If a part number contains the change from its first
production unit, the EFFECTIVITY column shows no data for that part
number.
C. Notes on Graphic Symbols
(1) Ground Symbols
We use different symbols for the signal ground, analog ground and
chassis ground as follows:
SIGNAL GROUND ANALOG GROUND CHASSIS GROUND
The analog ground symbol shows only on Figure 110A (A8 card). The
analog ground and signal ground are connected together on the A8
card. The signal ground also connects to the chassis ground through
the A3 card and J1 connector.
