the adjustment remote commander (Note 1). To set to the
Camera mode, set the power switch to “CAMERA“ or set the
“Forced Camera Power ON mode” using the adjustment remote
commander (Note 2). After completing adjustments, be sure to
exit the “Forced VTR Power ON Mode” or “Forced Camera
Power ON Mode”. (Note 3)

removing the cabinet (R) (removing the VC-206 board CN9912)
means removing the lithium 3V power supply (LI-64 board) ,
data such as date, time, user-set menus will be lost. After
completing adjustments, reset these data. If the cabinet (R) has
been removed, the self-diagnosis data, data on history of use
(total drum rotation time etc.) will be lost. Before removing,
note down the self-diagnosis data and the data on the history

Adjusting Connectors
Some of the adjusting points of the video section are concentrated
at VC-206 board CN9903. Connect the measuring instruments via
the CPC-8 jig (J-6082-388-A). The following table lists the pin
numbers and signal names of CN9903.

Checking the Input Signals
(Except AEP/UK model)
(Except AEP/UK model)
Because the video signal obtained from the pattern generator is used
as the adjustment signal for adjusting the VTR section, the video
output signal must satisfy the given specifications. Connect the
oscilloscope to the video terminal of the AUDIO/VIDEO jack, and
check that the sync signal amplitude of the video signal is
approximately <0.286V> [0.30V], the amplitude of the video section
is approximately <0.714> [0.70V], the amplitude of the burst signal
is approximately <0.286> [0.30V] and flat, and that the level ratio
of the burst signal to the “red“ signal is 0.30 : 0.60. The video signal
used for adjusting the video section is shown in Fig. 5-3-3.
