Notes on chip component replacement
I Never reuse a disconnected chip Component.
0 Notice that the minus side of a tantalum capacitor may be
damaged by heat.

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

SAFETY CHECK-OUT

After correcting the original service problem, perform the following
safety check 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 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 ch s, 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" indication
is 0.75 V, so analog meters must have an accurate low-voltage
scale. The Simpson 250 and Sanwa SH-63Trd are examples
ofa passive VOM that is suitable. Nearly all battery operated
digital multimeters that have a 2 V AC range are suitable. (See
