4-1. GENERAL

This set provides the Overall adjustment mode (Assy mode) that
allows CD and MO disk to be automatically adjusted when in the
test mode. In this Assy mode, the system discriminates between
CD and MO disk and then automatically perform adjustments for
them in sequence. If a fault is found, the system displays its loca-
tion. Also, the Servo mode allows each individual adjustment to be
automatically adjusted.
