Precautions
• Terminal resistor
Which drive must
or
must
not
be
fitted
with
a terminal resistor
is
dependent on
the
combina-
tion
or
number
of
drives
to
be
used.
For
prevention
of
troubles, every drive
leaves
our
plant
with
any terminal resistor
not
attached. When
mounting
a terminal resistor,
read
the directions given
later carefully and attach the resistor
to
a right drive. I mproper attachment could
cause
damages
to
connected drives.
• Upgrading
the
drive system
A
maximum
of
four
MZ-80SFDs
can
be
used
in daisy-chain connection
or
the MZ-80FB
or
MZ-80FB
K-
an
extension drive
unit
for
the
MZ-80FB-
can
be
used
in
conjunction
with
one
or
two
MZ-80SFDs
to
upgrade the drive system. When upgrading the drive system, interconnect
necessary drives in the specified manners shown later. Incorrect interconnection
will
destroy the
drive signal
circuit.
• Connection
with
the
computer
system
When connecting any drives
to
the
computer
system,
be
sure
to
switch
off
the whole system in
advance.
• Power supply
Be
sure
to
use
a supply voltage
that
is
shown on the rating plate attached
to
the back
of
the
MZ-80SFD. The
use
of
any
other
supply voltage
causes
damages
to
the drive. Also, never connect
the
MZ-80SFD
to
the
same
electrical
outlet
where some apparatus
that
generates a noise - a
heavy-duty
motor,
etc. -
is
connected, otherwise the system could
malfunction.
•
Humidity
and
dust
The MZ-80SFD, a precIsion engineered gadget, dislikes
an
excessive
humidity.
Avoid using this
drive in a location
that
is
subject
to
high
humidity
or
exposed
to
much dust.
(Ambient
humidity
= 20
to
80%)
• Installation
requirements and impact
The
MZ-80SFD
is
composed
of
precision engineered mechanisms and electronical components.
Use
it
in a location
that
is
not
subject
to
an
extreme high
or
low
temperature,
abrupt
temperature
changes,
or
heavy vibration
or
exposed
to
much dust. Never give any unreasonable impact
to
this
device
by
putting
something on
it
or
dropping
it
by
mistake. Also, never place
it
near a speaker,
TV
set,
or
tape recorder because these are generating magnetism. This
will
cause
malfunction
ef
the drive
or
delete data
or
texts stored in a diskette.
Never operate the
MZ-80SFD slanted. This
will
impede correct
writing
or
reading.
Also, place the
signal cables
of
the system kept
as
far away
as
possible
from
the
other
associate
devices and the power cords.
• Power cord
Be
careful
not
to
place a desk
or
chair on the power cord
or
catch
it
in anything, otherwise the
cord could
be
damaged. The
use
of
a damaged power cord
leads
to
hazard. When disconnecting the
power cord,
be
sure
to
pull
it
off
by
holding the plug.
• When the MZ-80SFD
is
expected
not
to
be operated over
an
extended period
of
time
Be
sure
to
disconnect
the
power cord
from
the electrical
outlet.
• Stain
If
the machine
is
contaminated, gently wipe
it
with
soft
cloth
soaked in water
or
cleaning
fluid.
Neither
use
any volatile chemicals such
as
benzine and
thinner
nor spread insecticide on the
machine. This
will
result in discoloration
of
the cabinet.
