3. Operating Instructions 4. Handling Precautions for Traverse Deck The laser diode in the traverse deck (optical pickup) may break down due to potential difference caused by static electricity of clothes or human body. So, be careful of electrostatic breakdown during repair of the traverse deck (optical pickup). 4.1. Handling the traverse deck (optical pickup) 1.
Fig. 1 Fig. 2 4.2. Grounding for electrostatic breakdown prevention 1.
Use the anti-static wrist strap to discharge the static electricity from your body. (as shown in Fig. 3 ) 2. Work table grounding Put a conductive material (sheet) or steel sheet on the area where the traverse deck (optical pickup) is placed, and ground the sheet. (as shown in Fig. 4 ) Caution The static electricity of your clothes will not be grounded through the wrist strap. So, take care not to let your clothes touch the traverse deck (optical pickup).

6.2.3. Off-set automatic adjustment 1. Remove the mechanism unit from the disc cover. Then move the optical pickup to the center, and attach the mechanism unit again to the disc cover. 2. With “T1E ” displayed, leave the disc cover open. 3. Pressing the key on the remote controller will start adjustment. 4. During adjustment, “FADJ ” is displayed on the LCD of the remote controller. If there is no abnormality, “FADJOK ” will be displayed. 5. Pressing the display mode.
4. Press key (“AOK ” or “ANG ” changes to “T2E ”). 5. After the adjustment is finished, remove the disc. 6.2.5. Playback-only disc automatic adjustment 1. Have “T3E ” indicated on display, set the playback-only disc. (Check to make sure the disc is properly seated.) 2. Press key of the remote controller. The adjustment is started. 3. During adjustment. “AADJ ” is displayed on the LCD of the remote controller. If there is no abnormality, “AOK ” will be displayed.
Main unit’s keys LCD display position and letters After the third key is pressed, the second digit displayed will change from “ ” to “O ”. VOL+ VOLHOLD OFF After the second key is pressed, the third digit displayed will change from “ ” to “O ”. The first digit displayed will change from “ ” to “O ”. 5. After all keys have been pressed and there is no abnormality, “T OOO ” will be displayed. 6. Perform below voltage check about the keys come under if it is not displayed “T OOO ”.
