VOLTAGE AND CYCLE CONVERSION
POWER
VOLTAGE ADJUSTMENT
The Mode! M-9
(M-9DX)
is
operatable anywhere
in the
world.
With
the
built-in stepdown power transformer, the user
can easily
readjust the recorder
to
any
one
of
the
six
stages of power voltage from 100 to 240 volts A.C.
Generally, the recorder's input voltage is preset for
the
forwarding territory.
The user is requested to
check
the previously
set voltage before
operation.
This can
be seen at
the rear of the
recorder.
If
another
voltage is required, readjusting
of the
voltage can
be
made in ac-
cordance
with the following instructions.
(1
)
Take
off
the ventilator
panel
by removing four mounting
screws as shown
in
Fig.
A.
Then, pull out the VOLTAGE CONVERSION SWITCH
@>
gently
and
reset the knob so that the desired voltage will
appear on
the
ventilator
panel.
(See Fig.
B)

The voltage
conversion
switch
is
a plug-in
type
movable in six steps,
100/
110/ 120/ 200/220/
240.
For
example, if
the
power
voltage
distributed
in
your
area is 220 volts
A.C.,
reset
the
switch
to
220
mark.
(3)
Change fuse according
tu
voltage.
Fuse:
IOOV~l20V
21\,
200V~240V
1 A
CAUTION:
Disconnect the
power plug
from the
AC
outlet
before readjust-
ing power
voltage.
To
mai
ntain optimum
performance
and
to
prolong the
!ife
of your
machine,
it
is
important
that the line
voltage be
held
within
10
percent
deviations from the
standard voltage.
POWER CYCLE CHANGE
Correct
tape
speed
is not obtainable
if the CYCLE CONVERSION
SWITCHES are not properly
adjusted.
The
CYCLE
CONVERSION
SWITCH
(A)
®
is
located
at
the
center of
the
deck
top
panel and
the
CYCLE CONVERSION
SWITCH
(B)
®
at the
rear
of
the
recorder.
Us-
ing a screw driver,
rotate
the CYCLE CONVERSION SWITCH
(A)
®
counter clockwise
approximately
one-eighth
of a
turn. The
switch can
then
be moved
either OUT or IN.
50
cycle operation
is
obtained by moving
the
switch OUT
(Fig. C), and
60
cycle
operation,
by
the switch IN
(F
ig. D).
The
switch
®
should be rotated
back
to its original
position
after it has
been moved
either OUT
or
IN.
The CYCLE
CONVERSION
SWITCH
Œ)
®
should also
·
be res et.
CAUTION
:
Do not attempt to rotate the
CYCLE
CONVERSION
SWITCHES
when
the
motor
is
not
running.
