SPECIAL NOTICE TO SERVICE PERSONNEL

1.  In order to insure safe operation of this product after servicing, at
    least one of the following measurements should be made to determine
    that exposed parts are acceptably insulated from the supply circuit:

    a)  Leakage Current
        The leakage current shall not be more than 0.5 mA at any
        accessible part.

    b)  Grounding Impedance

        The impedance of the grounding path at 60 Hz shall not exceed 0.1
        ohm when measured from the grounding means of the product to the
        accessible conductive part.

    c)  Dielectric Voltage Test
        There shall be no evidence of dielectric breakdown as a result of
        the application of:
        1)  1080V, 50 or 60 Hz, or 1530V DC for a period of 1 second or
        2)  900V, 50 or 60 Hz for a period of 1 minute, between parts
            involving electric shock and accessible conductive parts.

PRODUCT SAFETY NOTICE

Many electrical and mechanical parts in this chassis have special
characteristics.  These characteristics often pass unnoticed and the
protection afforded by them cannot necessarily be obtained by using
replacement components rated for higher voltage, wattage, etc.
Replacement parts that have these special safety characteristics are
identified in this manual and its supplements, electrical components
having such features are identified by a rectangle in the schematic
diagram and the parts list.  Before replacing any of these components,
read the parts list in this manual carefully.  The use of substitute
replacement parts that do not have the same safety characteristics as
specified in the parts list may create shock, fire, or other hazards.
