1-1 Safety Precautions
1. Be sure that all built-in protective devices are
in place. Restore any missing protective
shields.
2. Make sure there are no cabinet openings
through which people- particularly children-
might insert fingers or objects and contact
dangerous voltages.
3. When re-installing chassis and assemblies, be
sure to restore all protective devices, including
control knobs and compartment covers.
4. Design Alteration Warning:
Never alter or add to the mechanical or
electrical design of this equipment, such as
auxiliary connectors, etc. Such alterations and
modifications will void the manufacturer's
warranty.
5. Components, parts, and wiring that appear to
have overheated or are otherwise damaged
should be replaced with parts which meet the
original specifications. Always determine the
cause of damage or overheating, and correct
any potential hazards.

7. 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
provide could be lost if a replacement
component differs from the original. This
holds true, even though the replacement may
be rated for higher voltage, wattage, etc.
Components critical for safety are indicated in
the parts list with symbols
replacement components that have the same
ratings, especially for flame resistance and
dielectric specifications. A replacement part
that does not have the same safety
characteristics as the original may create
shock, fire, or other safety hazards.
