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.
0π: US model 1π: Canadian model 2π: Australian model 3π: AEP, German model 5π: UK model 7π: E model 8π: Singapore model
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 v oltage drop across a resistor by means of a V OM or battery-operated AC voltmeter. T he “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)

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 pick-up block. Therefore, when checking the laser diode emission, observe from more than 30 cm away from the objective lens.
LASER DIODE AND FOCUS SEARCH OPERA TION CHECK
Carry out the “S curve check” in “CD section adjustment” and check that the S curve waveform is output.

TEST MODE

4-1. AF MODE
The following checks can be performed in the AF mode, which is set by connecting the test point (AFJ) terminal on DISPLAY board to the Ground and turning on the power.
• FL tube check
After all segments light up, when the ≠0 button is pressed, the following will be displayed. (Partial lighting 1)
(Partial lighting 1)
When the button is pressed, the following will be dis­played. (partial lighting 2)
(Partial lighting 2)
When the p button is pressed, all will light up again.
4-2. ADJ MODE
The following operations are performed in the ADJ mode, which is set by connecting the test point (ADJ) terminal to the Ground and turning on the power.
• Servo related manual operations and measurement can be performed. (For details of operations, refer to Table of Key Operations in ADJ Mode.)
TABLE OF BUTTON OPERATIONS IN ADJ MODE
The functions of the number buttons are shown in the following table.
