CAUTION

Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous
radiation exposure.

Flexible Circuit Board Repairing
0 Keep the temperature of the soldering iron around 270°C during
repairing.
- Do not touch the soldering iron on the same conductor of the
circuit board (within 3 times).
0 Be careful not to apply force on the conductor when soldering
or unsoldering.

Notes on Chip Component Replacement
- Never reuse a disconnected chip component
- Notice that the minus side of a tantalum capacitor may be
damaged by heat

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.

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»54OA. 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.

31 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
