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-351 board, power
switch, microphone unit) has been removed. When removing
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-23 board need not be
connected except during battery end adjustment. To remove,
disconnect the following connectors.

4)

Cabinet (R) (Camera function switch (CF-56 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-56 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 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.
