CAUTION:
For continued safety, replace safety critical components only with manu-
facturer's recommended parts (refer to parts list).
indicates safety critical compo-
nents. 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 mea-
surements shall be carried out (exposed parts are acceptably insulated from the sup-
ply 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 mea-
surement value may vary depending on the measuring
instruments used or on the product.
