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 childrenmight insert fingers or objects and contact moving parts or 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. 8. Components critical for safety are indicated in the parts list with symbols . Use only 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. 6. Observe the original lead dress, especially near sharp edges, AC, and high voltage power supplies. Always inspect for pinched, out-ofplace, or frayed wiring. Do not change the spacing between components and the printed circuit board. SF150T 1-1 Precautions 1-2 ESD Precautions Certain semiconductor devices can be easily damaged by static electricity. Such components are commonly called "Electrostatically Sensitive (ES) Devices", or ESDs. Examples of typical ESDs are: integrated circuits, some field effect transistors, and semiconductor "chip" components. The techniques outlined below should be followed to help reduce the incidence of component damage caused by static electricity. CAUTION: Be sure no power is applied to the chassis or circuit, and observe all other safety precautions. 1. Immediately before handling a semiconductor component or semiconductor-equipped assembly, drain off any electrostatic charge on
