NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT
The laser diode in the optical pick-up block may suffer electrostatic break-down because of the potential difference generated by the charged electrostatic load, etc. on clothing and the human body.
During repair, pay attention to electrostatic break-down and also use the procedure in the printed matter which is included in the repair parts.
The flexible board is easily damaged and should be handled with care.
NOTES ON LASER DIODE EMISSION CHECK
The laser beam on this model is concentrated so as to be focused on the disc reflective surface by the objective lens in the optical pickup block. Therefore, when checking the laser diode emission, observe from more than 30 cm away from the objective lens.
LASER DIODE AND FOCUS SEARCH OPERATION CHECK
Carry out the “S curve check” in “CD section adjustment” and check that the S curve waveform is output four times.

Note: Set the test mode using the following method and begin tape speed adjustment.
In the test mode, the speed will switch to double speed or normal speed each time the HI DUB button is pressed.
Procedure:
With the power turned ON, press the p button, ENTER/NEXT button, and DISC 3 button simultaneously.
(The “CD TYPE INDICATOR” on the fluorescent display tube will blink while in the test mode.)
To exit the test mode, press the 1/u button.

2.Press the ( button of deck B.
3.Press the HI DUB button and play the tape at double speed.
4.Adjust RV1001 of the LEAF SW board so that the reading of the frequency counter becomes 6000 ± 180 Hz.
5.Press the HI DUB button and play the tape at normal speed.
6.Adjust RV1002 of the LEAF SW board so that the reading of the frequency counter becomes 3000 ± 90 Hz.

Procedure:
INTRODUCTION
When set to the test mode performed in Tape Speed Adjustment, when the tape is rewound after recording, the “REC memory mode” which rewinds only the recorded portion and playback is set.
This “REC memory mode” is convenient for performing this adjustment. During recording, the input signal FUNCTION will automatically switch to VIDEO.
(After recording, press the –0 button without stopping will return to the position where recording was started.)
1.Press FUNCTION button to select VIDEO. (This step is not necessary if the above test mode has already been set.)
2.Insert a tape into deck B, press the r REC button, and then press the ( button to start recording.

Note:
1.CD Block is basically constructed to operate without adjustment. Therefore, check each item in order given.
2.Use YEDS-18 disc (3-702-101-01) unless otherwise indicated.
3.Use an oscilloscope with more than 10MΩ impedance.
4.Clean the object lens by an applicator with neutral detergent when the signal level is low than specified value with the following checks.
