forward/rewind
lever
employs
2-step operation.
Raising the

lowering the lever
one
step
is
used
for fast
rewind. Fast
forward/rewind

raising or
lowering
the lever
again
one
step.
Raising or lowering the
fast for-
ward/rewind lever
two steps
(as far

four
seconds
of silence
exist
between

However, excessive record
player stylus noise,
due
to
dust or scratches
on
the record
on
home-recorded tapes
may
interfere
with these func-
tions.
The cassette automatically ejects
from
the unit
if
tape
setting
operations
cannot be completed
within
a few
sec-
onds. This
may
be caused

inherent
in
cassettes by "encoding" the tape.

will
decrease
high
frequency response.
By
not using the
Dolby
NR
