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-
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 depending on the measuring instruments
used or on the product. Bias circuit DC voltage is
measured while in the record mode.
