CAUTION : For continued safety, re-
place safety critical components only
with manufacturer's recommended parts
(refer to parts list).
Indicates safety critical components.
6 To reduce the risk of electric shock,
leakage-current or resistance measure-
ments 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.
