The DC voltage is an actual reading measured with a high impedance type volt-
meter with no signal input. The measurement value may vary depending on the
measuring instruments used or on the product.
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 insu-
lated from the supply circuit) before the appliance is returned to the customer.
