Caution
1. Caution
The lightning flash with arrowhead symbol, within an equilateral triangle, is
intended to alert the user to the presence of uninsulated “dangerous voltage”
within the product’s enclosure that may be of sufficient magnitude to constitute a
risk of electric shock to persons.
The exclamation point within an equilateral triangle is intended to alert the user to
the presence of important operating and maintenance (servicing) instructions in
the literature accompanying the appliance.
Precautions During Servicing
1. 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 selection switches, RF cables,
noise-blocking capacitors, noise-blocking filters, etc.
2. Use specified internal Wiring. Note especially:
1) Wires covered with PVC tubing
2) Double insulated wires
3) High voltage leads
3. Use specified insulating materials for hazardous live parts. Note especially:
1) Insulating Tape
2) PVC tubing
3) Spacers (insulating barriers)
4) Insulating sheets for transistors
5) Plastic screws for fixing micro switches
4. When replacing AC primary side components(transformers, power cords, noise
blockin capacitors, etc.), wrap ends of wires securely about the terminals before
soldering.
