PRODUCT SAFETY
NOTICE
Each precaution in this manual
should be followed during
servicing. Components
identified with the IEC symbol
!
!! in the parts list and the
schematic diagram designated
components in which safety can
be of special significance. When
replacinga component identified
by !
!! , use only the replacement
parts designated, or parts with
the same ratings of resistance,
wattage or voltage that are
designated in the parts list in this
manual. Leakage-current or
resistance measurements must
be made to determine that
exposed parts are acceptably
insulated from the supply circuit
before returning the product to
the customer.
This is a basic schematic diagram
