The
head
line-up
of
the
Model
A-1250S
as
seen
from
the
front
is
as
shown
in
the
photo.
_Since

head
functions
throughout
the
recording
-ode,
if
a
pre-recorded
tape
is
used
for

head
and
a

the
recording
head.
To erase all recordings
To
only
erase
the
tape,
the
MIC
and
LINE
knobs
are
fully

counterclockwise
to
prevent
any
sound
from
being
recorded,
the
tape
started
in
the
stereo
recording
mode,
2
tracks
(tracks

After
completing

the
reels
are
interchanged
and
the

Precaution at stop-and-go recording
When
you
do
intermittent

recorded tape, a portion of the old recording will remain
unerased at the point where the STOP button is depressed.
To prevent such fault, always completely erase the tape of
old recordings before you start recording.
During
long
periods
of
use,
the
heads
will
become
slightly
magnetized.
As
a
result,
the
high
frequency
will
decrease,
noise
will
develop,
or
in
extreme
cases
the
high
regions
will
drop
out
or
introduce
noise
into
your
valued
pre-recorded
tapes.
To
keep
your
recorder
operating
at
optimum
effi-
ciency
the
heads
should
be
demagnetized
at
least
once
for
every
50
hours
of
use,
with
a
TEAC
Model
E-1

using
the
procedures
outlined
below:
1
Turn
off
