The laser component in this product is capable of emitting radiation exceeding the limit for Class 1.
SAFETY CHECK-OUT After correcting the original service problem, perform the following safety checks before releasing the set to the customer: Check the antenna terminals, metal trim, "metallized" knobs, screws, and all other exposed metal parts for AC leakage. 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 microampers). Leakage current can be measured by any one of three methods. 1. A commercial leakage tester, such as the Simpson 229 or RCA WT-540A. Follow the manufacturers' instructions to use these instruments. 2. A battery-operated AC milliammeter. The Data Precision 245 digital multimeter is suitable for this job. 3. Measuring the voltage drop across a resistor by means of a VOM or battery-operated AC voltmeter. The "limit" indication is 0.75 V, so analog meters must have an accurate low-voltage scale. The Simpson 250 and Sanwa SH-63Trd are examples of a passive VOM that is suitable. Nearly all battery operated digital multimeters that have a 2V AC range are suitable. (See Fig. A)
This appliance is classified as a CLASS 1 LASER product. The CLASS 1 LASER PRODUCT MARKING is located on the rear exterior. The following caution label is located inside the unit.
CAUTION Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.

In this adjustment, waveform varies at intervals of approx. 2%. Adjust the waveform so that the specified value is satisfied as much as possible. (Write power traverse adjustment) (Traverse Waveform)
17. Press the YES button, display "EFB = SAVE" for a moment and save the adjustment results in the non-volatile memory. Next "EFBAL ADJUST" will be displayed. 18. Press the §EJECT button and remove the check disc (MD) TDYS-1. Note 1 : MO reading data will be erased during if a recorded disc is used in this adjustment. Note 2 : If the traverse waveform is not clear, connect the oscilloscope as shown in the following figure so that it can be seen more clearly.

Press the YES button and display "CPLAY MID". 4. Press the NO button when "C1 = AD = " is displayed. 5. Rotate the AMS knob and display "FBIAS ADJUST". 6. Press the YES button and display " / a = ". The first four digits indicate the C1 error rate, the two digits after [/] indicate ADER, and the 2 digits after [a =] indicate the focus bias value. 7. Rotate the AMS knob in the clockwise direction and find the focus bias value at which the C1 error rate becomes 220 (Refer to Note 2). 8. Press the YES button and display " / b = ". 9. Rotate the AMS knob in the counterclockwise direction and find the focus bias value at which the C1 error rate becomes 220. 10. Press the YES button and display " / c = ". 11. Check that the C1 error rate is below 50 and ADER is 00. Then press the YES button. 12. If the "( )" in " ( )" is above 20, press the YES button. If below 20, press the NO button and repeat the adjustment from step 2. 13. Press the §EJECT button to remove the continuously recorded disc. Note 1 : The relation between the C1 error and focus bias is as shown in the following figure. Find points a and b in the following figure using the above adjustment. The focal point position C is automatically calculated from points a and b. Note 2 : As the C1 error rate changes, perform the adjustment using the average vale.
