PRECAUTIONS DURING SERVICING
1. Parts identiﬁed by the A symbol parts are critical
for safety. Replace only with parts number specified.
2. In addition to safety other parts and assemblies are
speciﬁed for conformance with such regulations
asthose applying to spurious rediation.
These must also be replaced only with speciﬁed
Examples: RF converters, tuner units, antenna selec-
tor switches. RF cables, noise blocking capacitors.
noise blocking ﬁlters, etc.
3. Use speciﬁed internal wiring. Note especially:
) Wircs covered with PVC tubing.
2) Double insulated wires
3) High voltage leads
4. Use speciﬁed insulating materials for hazardous live
parts. Note especially:
1) Insulation Tape
) PVC tubing
3) Spacers (Insulating Barriers)
) Insulation sheets for transistors
) Plastic screws for ﬁxing mieroswitch (espe»
cially in turntable)
5. When replacing AC primary side components
(transformers. power cords. noise blocking
capacitors. etc). wrap ends of wires securely about
the terminals before soldering.
6. Observe that wires do not contact heat producing
parts (heatsinks. oxide metal ﬁlm resistors. fusible

7, Check that replaced wires do not contact sharp
edged or pointed parts.
8. Also check areas surrounding repaired locations.
Use care that foreign objects (screws. solder dro-
plets, etc.) do not remain inside the set.
SAFETY CHECK AFTER SERVICING
Confirm the speciﬁed insulation resistance between
power cord plug prongs and externally exposed parts of
the set is greater than 10 Mohms, but for equipment with
external antenna terminals (tuner, receiver, etc.) and is
intended for m or E, speciﬁed insulation resistance
should be headphone jacks. line»in-out jacks etc.) more
than 2.2 Mohms (groud terminals, microphone jacks.
headphone jacks, line—in-out jacks etc.)
VOLTAGE CONVERSION (ml model only)
Before connecting the power cord, turn the VOLTAGE
SELECTOR located on the Rear panel with a screw,
driver untill the correct voltage is indicated.
