can be of special significance.
When replacing a component
identified by

t h e r e p l a c e m e n t p a r t s
designated, or parts with the
same ratings of resistance,
wattage or voltage that are
designated in the parts list in this

resistance measurements must
be made to determine that
exposed parts are acceptably
insulated from the supply circuit
before returning the product to
the customer.
