CAUTION : For continued safety,
replace safety critical components
only with manufacturer's recom-
mended parts (refer to parts list).
Indicates safety critical compo-
!
nents. To reduce the risk of electric
shock, leakage-current or resistance
measurements shall be carried out
(exposed parts are acceptably insu-
lated from the supply circuit) before
the appliance is returned to the cus-
tomer.
• DC voltages are as measured with
(1/2)
a high impedance voltmeter. Val-
ues may vary slightly due to varia-
X25
tions between individual instru-
2/2
ments or/and units.
