3-1-2. Precautions on Adjusting
1)
The adjustments of this unit are performed in the VTR mode
or camera mode.
To set to the VTR mode, set the power switch to “VTR” (or
“PLAYER”) or set the “Forced VTR Power ON mode” using
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)
or camera mode.
To set to the VTR mode, set the power switch to “VTR” (or
“PLAYER”) or set the “Forced VTR Power ON mode” using
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”.

2)
The front panel block (MA-358 board, microphone unit, audio/
video jack , MIC jack) must be assembled because the audio/
video jack is used for connecting the monitor TV. To remove,
disconnect the following connector.

3)
Cabinet (R) (CK-80 board, LCD block) need not be connected
except during “Battery End Check”, “PLL Adjustment” and
“IR transmitter adjustments”. But removing the cabinet (R)
(removing the VC-217 board CN2906) means removing the
lithium 3V power supply (CK-84 board, BT8600) , 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 use
(data of page: 2, address: A2 to AA). (Refer to “SELF-
DIAGNOSIS FUNCTION” for the self-diagnosis data, and to
“5-4.Service Mode” for the data on the history use.)

(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.
