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 accept-
ably insulated from the supply circuit) be-
fore the appliance is returned to the cus-
tomer.
• DC voltages are as measured with a high
impedance voltmeter. Values may vary
slightly due to variations between indi-
vidual instruments or/and units.
