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 mea-
surements shall be carried out (exposed parts are ac-
ceptably 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.
