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 “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 “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)
2)
By setting the “Forced VTR Power ON mode” or “Forced
Camera Power ON mode”, the video section can be operate
even if even if the front panel block (MA-353 board, power
switch, microphone unit) has been removed. When removing
the front panel block disconnect the following connector.

the front panel block disconnect the following connector.
1. VC-214 board CN903 (20P 0.5mm)
3)
The lens block (CD-209 board) and VL-25 board need not be
connected except during battery end adjustment. To remove,
disconnect the following connectors.
1. VC-214 board CN501 (16P, 0.5mm)
2. VC-214 board CN551 (24P, 0.5mm)
3. VL-25 board CN151 (8P, 0.5mm)
connected except during battery end adjustment. To remove,
disconnect the following connectors.

3. VL-25 board CN151 (8P, 0.5mm)
4)
Cabinet (R) (Camera function switch (CF-58 board), LCD
block, viewfinder) need not be connected. But removing the
cabinet (R) (removing the VC-214 board CN911) means
removing the lithium 3V power supply (CF-58 board BH001),
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 data on history use (data
of page: 2, address: A2 to AA). (Refer to the “Service Mode”
for the data on the history use.) To remove the cabinet (R),
disconnect the following connectors.
1. VC-214 board CN911 (50P, 0.5mm)
2. DD-117 board CN933 (10P, 1.0mm)
