Precautions on Adjusting
1)
Disconnecting the VC-250 board CN926 (4P, 0.8mm) means
disconnecting the lithium 3V power supply (FP-571 board
BT001), data such as date, time, user-set menus will be lost.
After completing adjustments, reset these data. If the CN926
has been disconnected, the self-diagnosis data, data on history
of use (total drum rotation time etc.) will be lost. Before
disconnecting, note down the self-diagnosis data (data of page:
2, address: B0 to C6) and data on history use (data of page: 2,
address: A2 to AA). (Refer to “5-4. SERVICE MODE” for the
self-diagnosis data and the data on the history use.)

As the video and audio jacks and LANC jack are provided on
the IO-68 board and the power switch is provided on the FP-
575 flexible board, these boards must be connected to the VC-
250 board. So remove the cabinet (R) assembly (IO-68 board
and FP-575 flexible and FP-246 flexible) from the cabinet
(upper) assembly and connect it to the following connector.
