SECTION 1
GENERAL

SAFETY CH ECK-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 chassis, must
not exceed 05 mA (500 microampers) Leakage
current can be measured by any one of three
methods.

I. A commercial leakage tester, such as the
Simpson 229 or RCA WT-540A. Follow the
manufacturers instmctions to use these instru~
ments.

2. A batteryvoperated 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 batteryeoperated AC volt-
meter. 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 Fig A)

SERVICING NOTE

ORepairing printed resistor

Cut both sides of the resistor and solder the carbon
resistor having same value in place of printed one of
the conductor side.

l/32Wcarbon resistor is supplied for the replacing
part of the printed resistor.

0Note for tape operation buttons

When replacing tape operation buttons, cut them
off and attach new parts with locking com-
pound,

ONote for audio mounted board replacement
Replacement part of audio mounted board is set
for CND modelt
When replacing audio mounted board of US, E
or AUS model, change the parts as shown
below.
