a
ROUTINE
MAINTENANCE
In
addition
to
the
normal
care
required
of
all
electronic
equip¬
ment,
the
cassette
recorder
section
of
your
280
requires
reg¬
ular
cleaning
and
demagnetizing
to
keep
it
in
top
operating
condition.
As
the
tape
passes
over
the
heads
and
guides,
and
between
the
pinch
roller/capstan
assembly,
a
small
amount
of
oxide
residue
is
left
behind.
This
physical
phenomenon
is
true
of
all
tapes
and
all
tape
recorders.
Cotton
swabs
and
proper
cleaning
solutions
should
always
be
handy.
NOTE:
AVOID
CHEAP
SWABS
THAT
ARE
SKIMPY
IN
THE
COTTON
DEPARTMENT—THEY
CAN
SCRATCH
THE
HEAD
SURFACES.
The
heads,
guides
and
capstan
shaft
should
be
cleaned
with
anhydrous
alcohol
solutions;
the
pinch
roller,
with
special
rub¬
ber
cleaning
solutions.
These
cleaning
agents
are
readily
available.
NOTE:
NO
ORGANIC
SOLVENTS
(such
as
lacquer
thinners)
should
ever
be
used
on
the
heads,
capstan
shaft
and
guides.
DO
NOT
USE
SILICONE
LUBRICANTS
ON
THE
PINCH
ROLLER!
This
will
increase
wow
and
flutter.
If
you
get
lazy
or
forgetful
and
allow
the
oxide
deposits
to
build-up,
performance
will
suffer
noticeably—especially
high-
end
response
and
wow
&
flutter.
If
you
have
total
disregard
for
these
routine
maintenance
procedures,
the
heads
could
become
magnetized
and
wreck
every
tape
you
try
to
play,
The
simplest
rule
to
follow
is:
CLEAN
AND
DEMAGNETIZE
BEFORE
EVERY
SESSION.
If
you*re
in
to
"all-nighters”
and
marathon
sessions,
do
it
every
8
hours.
(Clean
your
tape
recorder
more
often
than
your
teeth!)
NOTE:
Use
either
a
hand
demag
netizer
(preferred)
or
a
demagnetizing
cassette
and
follow
the
instructions
of
the
manufacturer
But
avoid
the
cassette
tapes
with
built-in
or
applied
cleaning
agents
because
too
many
of
them
contain
an
abrasive.
