CAUTION : For continued safety, replace safety
critical components only with manufacturer’s rec-
ommended parts (refer to parts list).

the risk of electric shock, leakage-current or resis-
tance measurements shall be carried out (exposed
parts are acceptably insulated from the supply cir-
cuit) before the appliance is returned to the cus-
tomer.
•DC voltages are as measured with a high imped-
ance voltmeter. Values may vary slightly due to
variations between individual instruments or/and
units.

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-

•DC voltages are as measured with a high
impedance voltmeter. Values may vary
slightly due to variations between indi-
vidual instruments or/and units.
