(models for all other countries except for

Australia). After tuning in any AM station,

turn off the receiver. Hold down the PRE-

POWER button. All preset stations will be

erased when you change the interval. To re-

set the interval to 10 kHz (or 9 kHz), repeat

the procedure.

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 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 voltage drop across a resistor by means of a

VOM or battery-operated AC voltmeter. The "limit" indica-

tion is 0.75 V, so analog meters must have an accurate low-

voltage scale. The Simpson 250 and Sanwa SH-63Trd are ex-

amples of a passive VOM that is suitable. Nearly all battery

operated digital multimeters that have a 2 V AC range are suit-

able. (See Fig. A)
