1)

Connect the adjustment remote commander to CN713 of VC-
272 board via I/F unit for LANC control (J-6082-521-A) and
CPC jig connector (J-6082-539-A). To operate the adjustment
remote commander, connect the AC power adapter to the DC
IN jack of I/F unit for LANC control, or connect the L series
Info-LITHIUM battery to the battery terminal of I/F unit for
LANC control.

2)

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 (Note1).
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 (Note2).
After completing adjustments, be sure to exit the “Forced VTR
Power ON Mode” or “Forced Camera Power ON Mode”.

4)

As removing the cabinet (R) assembly (removing CN709 of
the VC-272 board) means removing the lithium 3V power
supply (CF-2000 block BT001), data such as date, time, user-
set menus will be lost. After completing adjustments, reset these
data. If the cabinet (R) assembly 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 and E0 to E2). (Refer
to “5-4.Service Mode”.)

5)

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.

3) Select page: 0, address: 01, and set data: 00.

When the FK-2000 block or the CF-2000 block is removed, the
VTR does an unusual movement for one minute after the power is
turned on. So, operate the VTR by the adjustment remote
commander (with the HOLD switch set in the OFF position) after
it passes for more than one minute.

Some of the adjusting points of the video section are concentrated
in CN713 of VC-272 board. Connect the Measuring instrument and
the adjustment remote commander via the I/F unit for LANC control
(J-6082-521-A) and CPC jig connector (J-6082-539-A) to CN713.
To operate the adjustment remote commander, connect the AC power
adapter to the DC IN jack of I/F unit for LANC control, or connect
the L series Info-LITHIUM battery to the battery terminal of I/F
unit for LANC control.
The following table shows the Pin No. and signal name of CN713.
