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 elec-
tric 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 measure-
ment value may vary depending on the measuring instruments used or on
the product. Bias circuit DC voltage is measured while in the record mode.
