Connect the equipment for adjustments according to Fig. 5-1-3.
Note 4:
As removing the cabinet (R) assembly (removing CN1005 of the
VC-281 board) means removing the lithium 3V power supply
(BT5201 on the CK-108 board), data such as date, time, user-set
menus will be lost. After completing adjustments, reset these data.
But the self-diagnosis data and the data on history of use (total
drum rotation time etc.) will be kept even if the lithium 3V power
supply is removed. (Refer to “5-4.Service Mode” for the self-
diagnosis data and the data on history of use.)
