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 resistance 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.
