2. Precation of Laser Diode
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. The traverse deck (optical pickup) is an extremely high-precision construction and must not be subjected to impact, excessive vibration, or other types of rough handling. 2. In order to prevent static electricity damage to the laser diode, use a short pin or similar tool to short the optical pickups flexible circuit boards after they have been disconnected from the main circuit board. (as shown in Fig. 1) 3. Handle the flexible circuit boards with care; excessive force could cause them to be broken. 4. Do not turn the pre-set variable resistor (for adjustment of the laser power); it has been adjusted at the factory. (as shown in Fig. 2)

Fig. 1

Fig. 2
4.2. Grounding for electrostatic breakdown prevention
1. Human body grounding 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. Measurements and Adjsutments
Note: After replacing the main components (optical pickup or traverse motor, etc.) of mechanism unit block, change to the adjust mode, and then perform the laser power adjustment, off-set autoadjustment and playback-only disc/magneto-optical disc auto-adjustment.
6.1. Instruments to prepare 1. Playback-only disc (Test disc RFKV0006)
2. Commercially available recordable disc (fully recorded with music) (magneto-optical disc) 3. Laser power meter (LE8010 or compatible meter) 4. Remote controller
Note: For use of MD cartridge type laser power meter, remove the intermediate cabinet before perform the laser power adjustment (as for the method of disassembly, refer to 5. Operation checks and main component replacement procedures.).
6.2. Laser power adjustment, Playback-only disc/magneto-optical disc auto- adjustment
6.2.1. Enter the adjustment mode
1. Set the battery and connect the remote controller. 2. Turn off the power, and switch main units HOLD switch off. 3. Press the buttons of the remote controller in order from 1 to 4 [ for (EB, EG, GCS) areas, refer to Fig. 5. For (GH) area , refer to Fig. 6.]

*In the display of T0** ~ TF** shown above, you must adjust T0**, T1**, T2** and T3**. You must perform the adjustment by observing the order T0** T1** T2** T3**.
6.2.2. Laser Power Adjustment
Adjust each laser power: read power for reading (play) and write power for writing (record). 6.2.2.1. Set the Unit to the Adjustment Mode Cautions
About handling the optical pickup and the magnetic head. - The optical pickup and the magnetic head are structured precisely; therefore, they are very fragile. Be careful not to touch them with the edge of the laser power meter. Do not touch the lens. - The sensor of the laser power meter is a very fine part. Be careful not to touch it to the optical pickup lens. - Do not loosen or remove the magnetic head installing screw. - The focus point of the laser reaches to 356F. Therefore, avoid adjusting using laser power for a long time because the sensor of the laser power meter may be burned. - Do not allow the write power to even momentarily reach or exceed 6mW. Doing so will result in damage to the optical pickup. - Do not set the unit to the laser power adjustment mode with the MD loaded. Doing so may result in damage to the MD. - Laser diode in the optical pickup may be destroyed by the staticelectricity generated in your clothes or body. Be especially careful with the static electricity.

Note: If it is displayed 10NG, check the Troubleshooting Procedures in the order.
6.2.5. Playback-only disc automatically adjustment
1. Have T3** indicated on display, and move the optical pickup to around center. 2. Set the playback-only disc. 3. Press the PLAY key of the remote controller (T3** changes to 10ADJ on the LCD, adjusment is started.). 4. If it has been finished normally, 10ADJ changes to 00OK (or 10OK) on LCD. If it is abnormally, it changes to 10NG. 5. Press the PLAY key (00OK or 10OK or 10NG changes to T3* *, playback-only disc adjustment is finished.).
6.2.6. How to get out the adjustment mode
Remove the battery when you finish the adjustment mode.

Result and measure If voltage at TP137 normal and voltage IC501 is unusual, check IC501 and switch periphery. If voltage at TP137 unusual, replace IC304. If drive wave form normal, check FPC condition of solder around lift motor, and nothing unusual is found, replace the motor. If drive wave form unusual, check supply voltage of IC401 and peripheral solder, and nothing unusual is found, replace IC401. If input wave form IC601 is unusual, check supply voltage of IC701 and peripheral solder, and if nothing unusual found, replace IC701. If input wave form IC601 is normal, check IC601 and perihperal circuit.

Optical input permits recording, but line input does not. MIC recording is impracticable.
Make sure of IC101 (pin 27) input wave form (during MIC/LINE input time).
9. Display of Self-Diagnostic Function
This model is equipped with a self-diagnosis function and shows, when necessary, the following indication in the LCD section of the set.

F15---This indication appears when the Down switch fails to turn ON since the magnetic head fails to move up/down normally (Due to trouble of the magnetic head or trouble of the magnetic head up/down motor) or the magnetic head P.C.B. is out of position or a foreign matter has mixed in or for some other reason. In such a case, check the peripheral parts of the magnetic head, repair or replace defective parts with normal ones.
