Philips N4450 - Maintenance and Controls

For splicing use special splicing tape. You can also use the
Philips’ splicing kit SK10.
Proceed as follows :
@ Pull the cover below the tape slot forwards.
@ Open the two black tape clips (Fig. 9).
© Insert the correct-part of the tape in the jig and close the
clips. The side of the tape facing the heads (dull side) should
face downwards. During splicing the reels need not be
removed from the recorder.
® Cut the parts to be removed by inserting a non-magnetic
tape-cutter in the diagonal guide slot (an oblique splice is
not audible during playback).
@ Place the ends to be spliced accurately against each other,
@ Apply a piece of adhesive tape of approx. 2 cm across the
ends. Check that the adhesive tape does not overlap the
magnetic tape; if necessary, cut off the protruding part.
Note: Take care that no pieces of tape drop into the recorder
during splicing: this may disturb the correct working of the
recorder.
7. REMOTE CONTROL
The
N
4450
tape
recorder
can
also
be
remote
controlled
with
the
aid
of
remote
control
unit
N
6719
(separately
available).
Connect
the
remote
control
unit
to
the
“REMOTE”
socket
(43)
with
the
recorder
switched
off,
as
otherwise
the
recorder
might
be
set
to
an
undesired
function.
8. CONTINUOUS TAPE REEL
The continuous tape reel EL 1907/52 (CE 10) can also be
mounted on the recorder.
The
recorder
can
then
be
used
for
recording
and
playback
with
the
continuous
tape
reel
(also
in
the
vertical
position).
@
Remove
the
ornamental
screw
between
the
reel
discs
of
the
recorder.
In
the
top-left
corner
of
the
storage
compart-
ment,
a
screw
with
a
round,
black
head
is
fitted;
pull
out
this
screw.
©
Place
the
continuous
tape
reel
over
the
hole
for
the
ornamental
screw
and
fit
the
special
screw
in
this
hole
through
the
hole
in
the
reel.
The
special
screw
should
not
be tightened too firmly.
©
The
endless
tape
reel
can
now
be
used
for
recording
and.
playback,
but
only
for
tape
transport
to
the
right:
tape
transport
to
the
left
will
damage
the
continuous
tape
reel
beyond
repair.
Fast
winding
is
not
possible
with
a
continous
tape
reel.
Note:
The
reel
discs
of
the
recorder
also
rotate
when
using
the
continuous
tape
reel,
but
this
is
of
no
consequence.
9. SLIDE SYNCHRONISER
The
recorder
may
also
be
used
in
conjunction
with
slide
syn-
chroniser
N
6400,
for
synchronising
slides
with
speech
and
music.
The
recorder
should
then
be
used
in
the
horizontal
position
and
the
slide
synchroniser
should
be
placed
to
the
left
or
right
of
the
recorder.
For
a
correct
synchronisation,
the
slide
synchroniser
should
be
in
the
same
place
during
recording
and
playback.

10. MAINTENANCE
When
normally
used
your
tape
recorder
requires
no
special
attention.
However,
it
is
advisable
to
remove
occassionally
the
dust
and
dirt
collected
on
the
heads,
since
this
may
adversely
affect
the
sound
quality,
especially
the
treble
tones
and
playback
volume.
We
therefore
recommend
that
you
clean
the
heads
from
time
to
time
by
playing
back
the
Philips
cleaning
tape,
type
811/CT.
This
tape
should
be
replayed
in
the
same
way
as
a
normal
audio
tape
in
position
playback.
After
playing
the
cleaning
tape,
the
heads
will
be
clean.
This
should
be
done
after
approx.
50
hours
of
use,
or
on
the
average,
once
a
month.
However,
if
the
heads
are
very
dirty,
proceed
as
follows:
®
Check
that
the
recorder
is
disconnected
from
the
mains.
©
Remove
the
head
cover
above
the
tape
slot
and
the
cover
below
the
tape
slot
by
pulling
them
forwards.
©
Clean
with
one
of
the
cleaning
swabs
supplied
with
the
recorder:
the
tape
tension
comparators
(4),
the
guide
rollers
(A),
the
tape
guides
(C),
the
front
of
the
heads
(D,
E,
F),
the
capstans
(B)
and
both
rubber
pressure
rollers
(Fig.
10).
If
the
dirt
is
persistent,
you
may
moisten
the
cleaning
swab
with
some
alcohol
or
methylated
spirit.
Never
use
any
other
cleaning
agents
than
those
mentioned
above
and
do
not
touch
the
heads
with
sharp
or
metal
objects.
©
The
drive
mechanism
should
not
be
lubricated.
©
Allow
all
parts
to
dry
before
refitting
the
head
cover
and
connecting
the
recorder
to
the
mains.
Furthermore,
we
recommend
that
you
have
your
recorder
checked
by
your
dealer
at
regular
intervals,
for
instance
once
a
year
or
in
the
case
of
very
intensive
use
at
shorter
intervals.
Your
dealer
will
clean,
check
and,
if
necessary
readjust
the
recorder,
and
parts
that
are
subject
to
wear
will
then
be
replaced
in
due
time.
Storage of tapes
Put
the
tape
in
its
box
immediately
after
use.
It
is
then
protected
against
dust
and
dirt
and
can
be
easily
taken
along.
Store
the
tapes
at
room
temperature,
not
near
loudspeakers
or
transformers,
and
not
in
the
sun.
