SERVICING NOTES
NOTES ON HANDLING THE OPTICAL PICK-UP |
BLOCK OR BASE UNIT
The laser diode in the optical pick-up block may suffer electrostatic
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 emission,
observe from more than 30 cm away from the objective lens.
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.
CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous
radiation exposure.
This appliance is classified as a CLASS 1 LASER product.
The CLASS 1 LASER PRODUCT MARKING is located on
the rear exterior.

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 microamperes).
Leakage current can be measured by any one of three methods.
1. Acommercial 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

Step 2: Setting the time
Before you can use the system’s timer functions,
set the internal clock.
The clock uses a 24-hour system on the European
model, and a 12-hour system on other models.
The 24-hour system is used here for illustration
purposes.
1 Press TIMER SET.
The hour indication flashes.
2 Press KKI/DDI repeatedly to set the
hour.
This section is extracted from
instruction manual.
3 Press ENTER.
The minute indication flashes.
4 Press KKI/DDI repeatedly to set the
minute.
5 Press ENTER.
The clock will begin operating.
To reset the system clock
You can reset the system clock even when the
system is on or off.
1 Press TIMER SET.
2 Press KX/DP>I repeatedly until
“SET CLOCK” appears, then press ENTER.
3 Repeat step 2 to 5 in “Step 2: Setting the time”.
Tip
If you make a mistake, start over from step 1.
