CAUTION : For continued safety, replace safety
critical components only with manufacturer’s
recommended parts (refer to parts list).
Indicates safety critical components. To re-
duce 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.
