For continued protection, replacement parts must be
identical to those used in the original circuit.
The use of a substitute replacement parts which do not
have the same safety characteristics as the factory
recommended replacement parts shown in this service
manual, may create shock, fire or other hazards.
AGAINST A RISK OF FIRE REPLACE ONLY WITH
SAME TYPE F701 (T2A, 250V), F702 (T2A, 250V)
AND F1702 (T4AL, 250V) FUSE.
(Fire & Shock Hazard)
the following safety checks:
between the chassis and other metal parts in the
and connect the DC power cable into the receiver's
DC jack. (Do not use an isolation transformer for this
resistor paralleled by a 0.15µF capacitor in series
with all exposed metal cabinet parts and a known
earth ground, such as electrical conduit or electrical
ground connected to an earth ground.
or higher, sensitivity or measure the AC voltage drop
across the resisor.
parts having a return to the chassis (antenna, metal
cabinet, screw heads, knobs and control shafts,
escutcheon, etc.) and measure the AC voltage drop
across the resistor.
All checks must be repeated with the AC cord plug
connection reversed. (If necessary, a nonpolarized
adaptor plug must be used only for the purpose of
completing these checks.)
Any reading of 35V peak (this corresponds to 0.7
milliamp. peak AC.) or more is excessive and
indicates a potential shock hazard which must be
corrected before returning the monitor to the owner.
oughly familiar with all safety checks and the servicing guidelines which follow:
