Procedures before and after replacing the PC I/F unit
1) Before replacing the PC I/F unit, write down the values for the parameters listed on the 2nd and 3rd pages of
the Adjustment Process A screen.
If the values for the parameters cannot be written down because the PC I/F unit is completely broken or for any
other reason, make all the adjustments in accordance with the paragraph for Adjustment procedure and
parameters, rather than the following procedures. (End)
Set the parameters listed on the 2nd and 3rd pages of the Adjustment Process A screen to the values you have
written down.
