NOTES ON CHIP COMPONENT REPLACEMENT

- Never reuse a disconnected chip component.

- Notice that the minus side ofa tantalum capacitor may be dam»
aged by heat.

SAFETY CHECK-OUT

After correcting the original service problem) perform the follow-
ing 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 chassis, must not exceed 0.5 mA (500 microamperes.).

Leakage current can be measured by any one ofthree 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 thisjob.

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 2 VAC range are suitable. (See
Fig. A)
