CAUTION: For continued safety, replace safety critical components only with manu-
facturer's recommended parts (refer to parts list). indicates safety critical compo-
nents. 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
m
depending on the measuring instruments used or on the product. Bias circuit DC
voltage is measured while in the record mode.
