Check leakage as described below. LEAKAGE The AC leakage from any exposed metal part to earth ground and from all exposed metal parts to any exposed metal part having a return to chassis, must not exceed 0. 5 mA (500 microamperes). [. . . ] However, the adjustment result of the temperature compensation offset adjustment remains unchanged. When this procedure is performed, be sure to perform all adjustments from very beginning to the end again except the temperature compensation offset adjustment. Perform this procedure as necessary before starting adjustment referring to section "5-4. Rotate the lAMSL knob to display "ADJ CLEAR" (C24). After pressing the YES button, "Complete!" appears for a moment and the initial setting is started. Then, "ADJ CLEAR" appears. 29 5-8. Recording and Displaying the IOP Information The IOP data that is indicated on the pickup, can be saved in the non-volatile memory of the MDS-JA555ES. The IOP data that is printed on the optical pickup and the IOP data after adjustment is completed can be saved in the memory. Saving the IOP data in the memory eliminates the needs to look at the printed value on the label that is attached on the surface of optical pick, and enables to view the IOP data on display. Rotate the lAMSL knob to display "Iop Write" (C28). @. @" (@ is arbitrary number. ) appears and the values that can be changed flash. Input the value of IOP that is written in the optical pick-up. Selecting figure: Rotate the lAMSL knob. @. @" (@ is arbitrary number. ) appears. The value of step 4 is used to record the adjustment result, so press the YES button. "Complete!" appears for a moment, and the value is recorded in the non-volatile memory. Rotate the lAMSL knob to display "lop Write" (C27) and press the YES button. . @/##. #" appears and the contents that is recorded are displayed. . @: The value of IOP that is described in pick-up ##. #: The value of IOP after adjustment 5. When the display is completed, press the lAMSL knob or MENU/NO button to display "Iop Read". 5-9. Temperature Compensation Offset Adjustment The temperature data at 25°C is used as the reference data and is saved in the non-volatile memory for offset adjustment. Do not perform this adjustment normally.
