SAFETY NOTICE
å
and shaded areas in the 
Replacement Parts List and
Schematic Diagrams.
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.
CAUTION:  FOR CONTINUED PROTECTION
AGAINST A RISK OF FIRE REPLACE ONLY WITH
SAME TYPE F701 (T2A, 250V), F702 (T2A, 250V)
AND F1702 (T4AL, 250V) FUSE.
WARNING
1. For continued safety, no modification of any circuit
should be attempted.
2. Disconnect AC power before servicing.
BEFORE RETURNING THE RECEIVER
(Fire & Shock Hazard)
Before returning the receiver to the user, perform
the following safety checks:
1. Inspect all lead dress to make certain that leads are
not pinched, and check that hardware is not lodged
between the chassis and other metal parts in the
receiver.
2. Inspect all protective devices such as non-metallic
3. To be sure that no shock hazard exists, check for
leakage current in the following manner.
»
Plug the AC cord directly into a 110~240 volt AC outlet,
and connect the DC power cable into the receiver's
DC jack. (Do not use an isolation transformer for this
test).
»
Using two clip leads, connect a 1.5k ohm, 10 watt
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.
»
Use an AC voltmeter having with 5000 ohm per volt,
or higher, sensitivity or measure the AC voltage drop
across the resisor.
»
Connect the resistor connection to all exposed metal
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.
