SECTION 4 ELECTRICAL ADJUSTMENTS 4-1. Precautions for Checking Laser Diode 4-3. Precautions for Adjustments Emission 1) When replacing the following parts, perform the adjustments and checks with ® in the order shown in the following table. To check the emission of the laser diode during adjustments, never view directly from the top as this may lose your eye-sight.
4-5. Temperature Compensation Offset Adjustment 4-6. Laser Power Adjustment Save the temperature data at that time in the non-volatile memory as Connection : Laser power 25 ˚C reference data. meter Note : 1. Usually, do not perform this adjustment. 2. Perform this adjustment in an ambient temperature of 22 ˚C to 28 ˚C.
4-7. Traverse Adjustment 11. Rotate the AMS knob until the waveform of the oscilloscope moves closer to the specified value. In this adjustment, waveform varies at intervals of approx. 3%. Connection : Adjust the waveform so that the specified value is satisfied as Oscilloscope much as possible.
4-8. Focus Bias Adjustment 4-9. Error Rate Check 4-9-1. CD Error Rate Check Adjusting Method : Checking Method : 1. Load a continuously recorded disc (Refer to “4-4. Creating MO 1. Load a test disc TDYS-1. Continuously Recorded Disc”.). 2. Rotate the AMS knob and display “CPLAY MODE”. 2.
