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.
