*SAFETY INSTRUCTIONS

PRECAUTIONS DURING SERVICING

1. Parts identified by the A symbol parts are critical
for safety, Replace only with pans number specified.
2. In addition to safety, other parts and assemblies are
specified for conformance with such regulations as
those applying to spurious radiation.
These must also be replaced only with specified
replacements
Examples: RF converters, tuner units, antenna

selector switches, RF cables,noise blocking capacitors,

noise blocking filters. etc.
3. Use specified internal wiring, Note especially:
1) Wires covered with PVC tubing
2) Double insulated wires
3) High voltage leads
4. else specified insulating materials for hazardous live
parts. Note especially:
1) Insulation Tape
2) PVC tubing
3) Spacers (Insulating Barriers)
4) Insulation sheets for transistors
5) Plastic screws for fixing rrricroswitch (especially
in turntable)
5 When replacing AC primary side components (trans-
formers, 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
resistors. etc).

*INFORMATION

7. Check that replaced wires do not contact sharp
edged or pointed parts.

8. Also check areas surrounding repaired locatoins.

9. Use care that foreign objects (screws, solder droplets
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 M ohms. but for equipment
with external antenna terminals (tuner, receiver, etc.)
and is intended for IE or I, specified insulation re-
sistance should be headphone jacks line-in-out jacks etc.
more than 2.2 M ohms (ground terminals, microphone
jacks).
