Removing CN006 (2P, 1.0mm) of VC-207 board means
removing the lithium 3V power supply (LI-65 board BT001) ,
data such as date, time, user-set menus will be lost. After
completing adjustments, reset these data. If CN006 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 the data on history use (data
of page: 2, address: 35 to 3D). (Refer to the “Service Mode”
for the data on the history use.)
