Check leakage as described below. LEAKAGE TEST 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). 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” indica- tion is 0.75 V, so analog meters must have an accurate low- voltage scale. The Simpson 250 and Sanwa SH-63Trd are ex- amples of a passive VOM that is suitable. Nearly all battery operated digital multimeters that have a 2 V AC range are suit- able. (See Fig. A) Fig. A.Using an AC voltmeter to check AC leakage. 1.5 k0.15 F AC voltmeter (0.75 V) To Exposed Metal Parts on Set Earth Ground The laser diode in the optical pick-up block may suffer electro- static 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 pick-up block. Therefore, when checking the laser diode emis- sion, 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 waveforms is output three times. Notes on chip component replacement Never reuse a disconnected chip component. Notice that the minus side of a tantalum capacitor may be dam- aged by heat. Flexible Circuit Board Repairing Keep the temperature of the soldering iron around 270 C dur- ing repairing. Do not touch the soldering iron on the same conductor of the circuit board (within 3 times). Be careful not to apply force on the conductor when soldering or unsoldering. NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT CAUTION Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous ra- diation exposure.

The CD-TEXT TEST DISC (TGCS-313:J-2501-126-A) is used for checking the display. To check, perform the following procedure. Checking Method: 1.Turn ON the power, set the disc on the disc table with the side labeled as “test disc” as the right side, close the front cover, and chuck the disc. 2.The following will be displayed on the fluorescent indicator tube. (The display switches each time the TIME/TEXT button is pressed.)

The title memo recording check mode is not required for servicing. Do not execute. ALL ERASE This mode is used for clearing information such as the title memo. Do not execute if information such as the title memo is not to be erased. Procedure: While pressing the CLEAR button with the power OFF, press the 1/ubutton and turn on the power. The fluorescent indicator tube displays “ALL ERASE” and all memories will be cleared. AGING MODE Mode which repeatedly changes and plays back discs automati- cally in the unit. It will repeat aging as long as no errors occur. If an error occurs during aging, it will stop all servos, motors, etc. instantaneously, display the error number, and stop opera- tions. However, the stopping conditions differ according to whether the unit is equipped with the “self-protection function during errors” described later. The function serves to maintain the state of the unit when errors occur. 1. Disc change 2. Load in 3. TOC read 4. Access of last track 5. 3 second playback 6.

This mode makes the setting of these discs more easy. *2 Self protection function during errors: Function which voluntarily corrects errors which occur dur- ing normal operations by retries. If this function is not provided, all operations will be stopped without retiring. It is suitable for checking errors with low re- producibility. If this function is provided, and errors can be corrected by retries, aging will be continued without stopping. *3 Aging cycle count function: Functions which displays the number of agings carried out on the Fluorescent indicator tube
