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 accept-
ably 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 volt-
meter with no signal input. The measurement value may vary depending on the
measuring instruments used or on the product.
