SECTION 4 TEST MODE 4-1. GENERAL Remote control LCD • When entered in the TEST MODE, this set provides the Overall Adjustment mode which allows CD and MO discs to be automatically adjusted. In the Overall Adjustment mode , the system discriminates between CD and MO discs, performs adjustments in sequence automatically, and displays the faulty location if any fault is found. In the Manual mode, selected adjustments can be performed automatically.

4-4. MANUAL MODE 4-4-1. Outline of the function Address Value & Adjustment Value The Manual mode is designed to perform adjustments and operational checks on the set’s operation according to each individual function. Usually, no adjustments are made in this mode. However, the Manual mode is used to clear the memory before performing automatic adjustments in the Overall Adjustment mode.
