Telefunken M 204 E - Oiling and Greasing; Demagnetisation (Degaussing); Operating Instructions; Track Selection and Recording Procedure

Oiling and Greasing
The
unit
is
fitted
with
self-lubricating
sintered
bearings
which
give
maintenance-free
operating
times
of
several
thousand
hours.
If
a
bearing
should
happen
to
run
with
much
friction,
it
is
advisable
to
replace
the
component
concerned.
Re-oiling
would
bring
about
the
danger
of
contaminating
the
drive
with
oil
spray.
The
sliders
of
the
actuator
rods
and
the
bearing
brackets
should
be
lubricated
at
the
bearing
points
with
Siemens
uniselector
grease,
and
with
Molykote
Paste
G
Rapid
at
all
places
where
metallic
components
slide
against
each
other
(e.g.
the
press-
button
assembly).
The
prismatic
bearing
for
the
drive
capstan
on
the
head
carrier
plate
is
also
lubricated
with
molykote.
Re-greasing
is
necessary
only
.after
replacing
components,
or
when
a
particular
component
does
not
run
freely.
Molykote
must
always
be
applied
as
an
extremely
thin
film.
Lubricating
grease
or
molykote
must
not
be
used
for
sintered
bearings.
Demagnetisation (Degaussing)
Tape
drive
components
and
magnetic
heads
may
become
magne-
tised
when
approached
with
magnetic
tools
or
cables
carrying
direct
current.
This
produces
a
permanent
background
noise
on
the
tapes
during
operation.
To
prevent
this
defect,
we
recommend
careful
and
thorough
degaussing
of
all
metallic
components
which
come
into
contact
with
the
tape,
after
every
completed
repair
job
(degaussing
choke
for
220
V
AC,
Order
No.
60.89.108).
All
adjustment
values
and
direction
specifications
refer
to
vertical
operation
of
the
unit.
Operating Instructions

“1/2", according as to whether trans-
cription is to be made from track 2
to track 1, or from track 1 to track 2
respectively. The drive level of the
new recording is always to be ad-
justed with the control @ and the
drive level of the transcription recor-
ding is always to be adjusted with
the control ®.
Recording. Turn the function selector switch @ to the desired
setting and press the recording button @. Then ad-
just the drive level for monaural recordings with the
control @, and for stereophonic recordings with
control @ for the left channel and control © for the
right channel. The meter pointers should deflect up
to the start of the red sectors on volume peaks,
excursians into the red sectors being at most very
brief. After correct drive adjustment, hold the recor-
ding button @ depressed and press the drive button
@) additionally thereto.
The stop button @) must be actuated prior to any
change of the operating mode.
