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 “VCR” 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)
To remove the cabinet (R), disconnect the following connector.
VC-265D board CN012 (60P, 0.4mm)
As the DC IN jack is connected to the BJ-002A board of the
cabinet (R), the board must be connected to the VC-265D board.
So remove the BJ-002A board and DC IN jack from the cabinet
(R). To remove them from the cabinet (R), disconnect the
following connectors. (The LCD block and battery terminal
need not to be connected. To operate VTR, use the adjustment
remote commander.)
1. BJ-002A board CN3107 (8P, 0.8mm)
2. BJ-002A board CN3106 (16P, 0.8mm)
3. BJ-002A board CN3105 (3P, 1.5mm)
And connect the BJ-002A board to the following connector of
VC-265D board.
VC-265D board CN012 (60P, 0.4mm)
3)
The Lens-EVF block need not to be connected. To remove them,
disconnect the following connector.
VC-265D board CN001 (88P, 0.4mm)
4)
As removing CN013 0f  VC-265D board (removing the control
switch block (FK-1770)) means removing the lithium 3V power
supply, data such as date, time, user-set menus will be lost.
After completing adjustments, reset these data. If the CN013
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 (data of page: 2, address: B0
to C6) and the data on history use (data of page: 2, address: A2
to AA). (Refer to “5-4.Service Mode” for the data on the history
use and the self-diagnosis data.)
5)
If the “Forced VTR power ON” mode is set, the control switch
block (PS-1770) need not be connected. To remove it,
disconnect the following connectors.
Control switch block (FK-1770) CN602 (8P, 0.5mm)
Note 1:
Setting the “Forced VTR Power ON” mode (VTR mode)
1) Select page: 0, address: 01, and set data: 01.
2) Select page: D, address: 10, set data: 02, and press the PAUSE
button of the adjustment remote commander.
The above procedure will enable the VTR power to be turned on
with the control switch block (PS-1770) removed.
After completing adjustments, be sure to exit the “Forced Power
ON mode”.
Note 2:
Setting the “Forced Camera Power ON” mode (Camera mode)
1) Select page: 0, address: 01, and set data: 01.
2) Select page: D, address: 10, set data: 01, and press the PAUSE
button of the adjustment remote commander.
The above procedure will enable the camera power to be turned
on with the control switch block (PS-1770) removed.
After completing adjustments, be sure to exit the “Forced Power
ON mode”.
Note 3:  
Exiting the “Forced Power ON” mode
1) Select page: 0, address: 01, and set data: 01.
2) Select page: D, address: 10, set data: 00, and press the PAUSE
button of the adjustment remote commander.
3) Select page: 0, address: 01, and set data: 00.
