SECTION 4 TEST MODE

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.
