3.3.5 Replacement of the Central-IO PCB assy.

After turning off the sub and main power switches, unplug the power cord. Make sure to take 15
minutes before restarting the operation. It is very dangerous if sleep mode functions mistakenly
during the operation.
Moreover, the PCB may be damaged in case electric charge still remains inside.
Also, there is a possibility of electric shock because of high power voltage applied to the high-pres-
sure part of the DC power supply unit. Take care to avoid contact with it.

At starting of the machine, if the machine was started in other than the system parameter input
mode, turn off the main power once, and then re-start the machine in the system parameter mode.
At that time, be sure not to turn off the power with the SUB power switch*1 on the operation
panel. Also, do not change the parameters. (The back-up data on the main PCB will be rewritten
and not return to the original.)
*1 : If the SUB power switch is pressed, input the system parameter INIT= " 1 ", and then download the parameters uploaded in the
procedure " 1 " after all parameters are initialized. (The procedure " 6 " is not required.)
Be sure to carry out the above parameters download in order to reflect the important parameters.
If this work is not carried out, the machine may not work properly.
