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

Specifications and components subject to change without notice.

Overall performance will be maintained or improved.

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 T0 EACH EXPOSED
METAL SURFACE OF

UNIT UNDER TEST

as nonmetallic control knobs, insulating
fishpapers, cabinet backs, adiustment
and compartment covers or shields,
isolation resistor-capacity networks, me-
chanical insulators, etc. which were
removed for servicing are properly

" reinstalled.

3. Be sure that no shock hazard exists; check for leakage
current using Simpson Model 229 Leakage Tester,
standard equipment item No. 2164i, 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.
