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 a cassette loaded at playback mode. The measurement value may
vary depending on the measuring instruments used or on the product. Bias circuit
DC voltage is measured while in the record mode.
