CAUTION : For continued
safety, replace safety critical
c o m p o n e n t s o n l y w i t h
m a n u f a c t u r e r ' s r e c o m -
mended parts (refer to parts
list).
Indicates safety critical
components. To reduce the
risk of electric shock, leak-
age-current or resistance
measurements shall be car-
ried out (exposed parts are
acceptably insulated from the
supply circuit) before the ap-
pliance is returned to the cus-
tomer.
• DC voltages are as mea-
sured with a high imped-
ance voltmeter. Values
may vary slightly due to
variations between indi-
vidual instruments or/and
units.
