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-cur-
rent 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 play-
back 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.
