CAUTION : For continued
safety, replace safety criti-
cal components only with
manufacturer’s recom-
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
appliance is returned to the
customer.
•
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.
