<Note>
When the initial factory settings 1 have been made, the initial factory settings 2 and the line adjustment data are
all cleared. This would require readjustments for all the modes.
Before replacing an IC, write down the data settings in all the modes. Note, however, that the settings may be
different from unit to unit. Take the above reference data as an adjustment guideline.
