facturer's recommended parts (refer to
parts list).
indicates safety critical com-
ponents. For continued pro-
tection 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 car-
ried 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.
