7.1 PARTS CHANGE OF NOTES

A
1. At shipment, the unit is adjusted to its best conditions. Normally, it is not necessary to readjust even if an assembly is replaced. If the
adjustment is shifted or if it becomes necessary to readjust because of part replacement, etc., perform the adjustment as described
below.
2. Any value changed in Service/Factory mode will be stored in memory as soon as it is changed. Before readjustment, take note of the
original values for reference in case you need to restore the original settings.
