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 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
5.0V
may vary slightly due to variations between individual instruments or/
and units.
