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 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.
