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).

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.
