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 sup-
ply circuit) before the appliance is returned to the cus-
tomer.
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.
