Precaution
6. Components, parts and wiring that appear to have overheated or that are otherwise damaged should be
replaced with parts that meet the original specifications. Always determine the cause of damage or overheating,
and correct any potential hazards
7. Observe the original lead dress, especially near the following areas: Antenna wiring, sharp edges, and
especially the AC and high voltage power supplies. Always inspect for pinched, out-of-place, or frayed wiring.
Do not change the spacing between components and the printed circuit board. Check the AC power cord for
damage. Make sure that no wires or components touch thermally hot parts.
8. Product Safety Notice:
Some electrical and mechanical parts have special safety-related characteristics which might not be obvious
from visual inspection. These safety features and the protection they give might be lost if the replacement
component differs from the original--even if the replacement is rated for higher voltage, wattage, etc.
9. Components that are critical for safety are indicated in the circuit diagram by shading, or . Use
replacement components that have the same ratings, especially for flame resistance and dielectric strength
specifications. A replacement part that does not have the same safety characteristics as the original might
create shock, fire or other hazards.
