CAUTION: For continued safety, replace safety critical components only with manufacturer's recommended
parts (refer to parts list).
indicates safety critical components. For continued protection against risk of fire,
replace only with same type and rating fuse(s). To reduce the risk of electric shock, leakage-current or resis-
tance measurements shall be carried out (exposed parts are acceptably insulated from the supply circuit) before
the appliance is returned to the customer.
The DC voltage is an actual reading measured with a high impedance type voltmeter with no signal input. The
measurement value may vary depending on the measuring instruments used or on the product.
