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. This caution label is located inside the unit.
To Exposed Metal Parts on Set
CAUTION Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.

3-8. Precautions for Use of Test Mode
1 As loading related operations will be performed regardless of the test mode operations being performed, be sure to check that the disc is stopped before setting and removing it. Even if the EJECT button is pressed while the disc is rotating during continuous playback, continuous recording, etc., the disc will not stop rotating. Therefore, it will be ejected while rotating. Always press the EDIT/NO button first before pressing the EJECT button. 2 The erasing-protection tab is not detected in the test mode. Therefore, when modes which output the recording laser power such as continuous recording mode and traverse adjustment mode, etc. are set, the recorded contents will be erased regardless of the position of the tab. When using a disc that is not to be erased in the test mode, be careful not to enter the continuous recording mode and traverse adjustment mode. 3 Most buttons can not be used while the error rate is displayed due to bugs of IC121 CXD2535CR.

Optical Pick-up IC171 1. Temperature compensation offset adjustment 2. Laser power adjustment 3. Traverse adjustment 4. Focus bias adjustment 5. Error rate check G ® ® ® ® ® ® ® ® ® BD Board D101 ® G G G G IC101, IC121, IC191 ®
4-2. Precautions for Use of optical pickup (KMS-210A)
As the laser diode in the optical pickup is easily damaged by static electricity, solder the laser tap of the flexible board when using it. Before disconnecting the connector, desolder first. Before connecting the connector, be careful not to remove the solder. Also take adequate measures to prevent damage by static electricity. Handle the flexible board with care as it breaks easily.

Press the ENTER/YES button twice and display "CPLAY MID". 4. "C1 = AD = " is displayed. 5. If the C1 error rate is below 50, check that ADER is 00. 6. Press the EDIT/NO button, stop playback, press the EJECT button, and remove the continuously recorded disc.
4-10. Focus Bias Check
Change the focus bias and check the focus tolerance amount. Checking Method : 1. Load a continuously recorded disc (Refer to "4-4. Creating MO Continuously Recorded Disc".). 2. Rotate the AMS knob and display "CPLAY MODE". 3. Press the ENTER/YES button twice and display "CPLAY MID". 4. Press the EDIT/NO button when "C1 = AD = " is displayed. 5. Rotate the AMS knob and display "FBIAS CHECK". 6. Press the ENTER/YES button and display " / c = ". The first four digits indicate the C1 error rate, the two digits after [/] indicate ADER, and the 2 digits after [c =] indicate the focus bias value. Check that the C1 error is below 50 and ADER is 00. 7. Press the ENTER/YES button and display " / b = ". Check that the C1 error is not below 220 and ADER is not above 00 every time. 8. Press the ENTER/YES button and display " / a = ". Check that the C1 error is not below 220 and ADER is not above 00 every time. 9. Press the EDIT/NO button, next press the EJECT button, and remove the continuously recorded disc. Note 1 : If the C1 error and ADER are above 00 at points a or b, the focus bias adjustment may not have been carried out properly. Adjust perform the beginning again.
