This specification is the target of servicing. But, there is a case
that the specification
is not
applicable
to the measurement

Specifications and components subject to change without notice.
Overall performance will be maintained or improved.
@ WEIGHT
Before returning the unit to the user, perform the following safety checks:
1. Inspect all lead dress to make certain
that leads are not pinched or that hard-
ware is not lodged between
the chassis
and other metal parts in the unit.
2. Be sure that any protective devices such

3. Be sure that no shock hazard exists; check for leakage
current using Simpson Model 229 Leakage Tester,
standard
equipment
item No. 21641,
RCA Model
WT540A or use alternate method as follows:
Plug the AC line cord directly into a 120-volt AC
receptacle (do not use an Isolation Transformer for
this test). Using two clip leads, connect a 1500 ohm,
10-watt resistor paralleled by a 0.15mf capacitor, in
series with
all exposed
metal cabinet parts and a
known earth ground, such as a water pipe or conduit.
Use a VTVM
or VOM with 1000 ohms per volt, or
higher, sensitivity to measure the AC voltage drop
across the resistor. (See Diagram.) Move the resistor
connection
to each
exposed
metal
part having
a
return
path to the chassis (antenna, metal, cabinet,
screw heads, knobs and control shafts, escutcheon,
etc.) and
measure
the AC
voltage drop across
the
resistor. (This test should be performed with the
power switch in both the On and Off positions.)
A reading of 0.35 volt RMS or more is excessive and
indicates a potential shock hazard which must be
corrected before returning the unit to the owner,
