CAUTION : For continued safety, replace
safety critical components only with
manufacturer’s recommended parts (refer to
parts list).
Indicates safety critical components. To reduce the risk of electric
shock, leakage-current
or resistance measurements shall be carried
out (exposed parts are
acceptably insulated
from the supply circuit)
before the appliance is
returned to the customer.
• DC voltages are as
measured with a high
impedance voltmeter.
Values may vary
slightly due to variations between individual instruments or/
and units.
