CAUTION:
For continued safe-
ty, replace safety critical com-
ponents only with manufactur-
er's recommended parts (refer
to parts list).
indicates safety
critical components. For contin-
ued protection against risk of
fire, replace only with same
type and rating fuse(s). To
reduce the risk of electric
shock, leakage-current or resis-
tance measurements shall be
carried out (exposed parts are
acceptably insulated from the
supply circuit) before the appli-
ance 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.
