4. By pressing the ^ key, focus is turned ON from focus searching while entering CLV-S. (draw-in mode) Without disc, focus searching is repeated continuously. 5. By pressing the PLAY MODE key, tracking servo, sled servo and CLV-A (servo in PLAY) are turned ON. 6. When step 4 and 5 are performed, playing begins. No muting is ON in the service mode. 7. By pressing the p key, all servos (focus, tracking and sled) are turned OFF. However, the disc motor revolves for a while by inertia. â¢ Step 3 (Resetting of service mode) 1. Be sure to disconnect the external power supply and remove the solder bridge at the TEST terminals connected before in setting. 2. The set thus becomes available for normal operation.

(pin %Â¢, IC801 (ESPSL/TEST) is grounded) 3. Connect an external power supply. Thus, the set is switched to the service mode. â¢ Step 2 (Operation in the service mode) 1. Once the service mode is effected, the LCD displays 5 indications each of which is repeatedly displayed. However, the following operations can be activated even if LCD indication is effected. 2. By pressing the + or = key, the optical pick-up is movable inwardly or outwardly.
