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 A C 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 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. Follo w 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 v oltmeter . The “limit” indication is 0.75 V, so analog meters must have an accurate low-v olta ge scale. The Simpson 250 and Sanwa SH-63Trd are e xamples of a passive VOM that is suitable. Nearly all battery operated digital multimeters that have a 2V AC range are suitable. (See Fig. A)

SERVICE NOTES
Laser component in this product is capable of emitting radiation exceeding the limit for Class 1.
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.
NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT
The laser diode in the optical pick-up block may suffer electrostatic breakdown because of the potential difference generated by the charged electrostatic load, etc., on clothing and the human body. During repair, pay attention to electrostatic breakdown 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 pick­up block. Therefore, when checking the laser diode emission, observe from more than 30 cm away from the objective lens.
CHUCK PLATE JIG ON REPAIRING
On repairing CD section, playing a disc without the CD lid, use Chuck Plate Jig.
Code number of Chuck Plate Jig : X-4918-255-1
CAUTION
Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.
LASER DIODE AND FOCUS SEARCH OPERATION CHECK
1. Press CD open knob.
2. Open the lid for CD.
3. Push on SWITCH (S801) as following figure.
4. Confirm the laser diode emission while observing the objecting lens. When there is no emission, Auto Po wer Control circuit or Optical Pick-up is broken. Objective lens moves up and down once for the focus search.

Notes on Check
1. Perform the traverse check in the CD test mode.
After check, be sure to exit the test mode.
2. Perform check in the order given.
3. Use the disc (YEDS-18, Parts No. 3-702-101-01) only when
so indicated.
Before Check
Put the set into test mode and perform the following checks. Repair if there are any problems.
• Sled Motor Check
Press + , = keys and confirm that the Optical pick-up moves smoothly from the innermost to outermost circumference and back smoothly and with no catching or abnormal noises. (Cancellation of BTL mute)
+ : Optical pick-up moves to the outer circumference. = : Optical pick-up moves to the inner circumference.
Focus Search Check
1. Press the CD ^ key. (Focus search operation is performed
continuously.)
2. Look at the Optical pick-up objective lens and confirm that it
moves up and down smoothly, with no catching or abnormal noises.
3. Press p button.
Confirm that focus search operation stops. If it does not, press p button again longer.
TRAVERSE Check
This check is to be done when the optical pick-up block is replaced.
Check Procedure:
1. Connect the oscilloscope to test point TP (VC) and TP (TE) on MAIN board.
2. Put the set into test mode.
3. Optical pick-up setting to the center by + or = button pushing.
4. Insert disk (YEDS-18) and press ^ button.
5. Check that the oscilloscope traverse waveform is symmetrical, as shown in the figure below.
6. Release test mode after adjustment is completed.

4. Insert disk (YEDS-18) and press ^ button.
5. Press the MODE button. (Tracking servo ON)
6. Check that the oscilloscope wavewform is as sho wn in the figure below (eye pattern). A good eye pattern means that the diamond shape () in the center of the waveform can be clearly distinguished.
7. Release test mode after adjustment is completed.

Focus/Tracking Gain Check
Adjustment Location : MAIN board (Component side)
(See page 16)
A frequency response analyzer is necessary in order to perform this check exactly. However , this gain has a mar gin, so e ven if it is slightly of f, there is no problem. Focus/Tracking gain determines the pick-up follo w-up (vertical and horizontal) relative to mechanical noise and mechanical shock when the 2-axis device operate.
Symptoms
Gain
• The time until music starts
becomes longer for STOP CD ^ or automatic selection (0 , ) buttons pressed). (Normally takes about 2 seconds.)
• Music does not start and disc continues to rotate for STOP CD ^ or automatic selection (0 , ) buttons pressed.)
• Sound is interrupted during PLAY. Or time counter display stops progressing.
• More noise during 2-axis device operation.
