tection against risk of fire,
replace only with same type

reduce the risk of electric
shock, leakage-current or
resistance measurements

The DC voltage is an actual
reading measured with a
high impedance type volt-
meter with a cassette loaded
at playback mode. The mea-
surement value may vary
depending on the measuring
instruments used or on the
product. Bias circuit DC volt-
age is measured while in the
record mode.
