The Casiotone MT-400V is a stereophonic keyboard. Fit two speak-
ers to the instrument as follows.
@ Insert hooks of speaker's stand into slots on rear panel. One
speaker for the aot and the other for the left. The speakers
e.
are interchangeab
@ Connect each speaker's cord to its corresponding jack.
@ Adjust the angle of speaker by turning lock knob to the left,
°
then fix it by turning the knob to the right.
* Speakers can be used remote from the instrument by using
stands.
The unit operates on both AC and DC power.
Dry batteries:
The unit works on six D size (SUM-1) manganese dry
batteries,
Weakened batteries will result in lower volume or poor
tonal quality. The power indicator lamp will gradually
lose its brightness when the battery power weakens.
At this time change batteries or shift to power sources
as mentioned below.
Battery replacement:
1. Slide open the battery compartment cover on the
bottom of the unit and take out used batteries.
2. Insert new batteries, taking care that polarity is
not reversed.
* It is advisable to replace all six batteries at the same
time for longer battery life.
* For battery life, refer to the specifications.
Car battery adaptor:
With the car battery adaptor (CA-5, optional), you can
take DC power from your car battery via a cigarette
lighter socket.
To connect the unit to an AC outlet, the AC adaptor
(AD-5, optional) is required.
aa,
Use only an adaptor with the same voltage rating (100,
117, 220, or 240V) as your power supply to prevent com-
nent damage.
lug the AC adaptor into the AC outlet and the cord
into the unit; this automatically cuts off battery power
supply.
1 When batteries are not used for a long period of time,
it is advisable to remove them from the battery com-
partment. (Battery leakage may occur and damage
electrical parts.)
* Auto power-off function
For power economy, an automatic power cut-off func-
tion activates after approximately 6 minutes, if you do
not touch the keys. r supply will be resumed by
switching the main power switch off and then on again.
CAUTION
* WHERE USED FROM THE MAINS THIS UNIT MUST
ONLY BE USED WITH A CASIO MAINS ADAPTOR
TO PREVENT THE RISK OF DAMAGE.
* When the adaptor is left connected to an AC outlet,
it may warm up, but this is quite normal. Disconnect
the adaptor whenever possible, especially if not used
for a long time.
The following misuse may lead to battery burst.
1. Use of an AC adaptor other than a genuine Casio
adaptor.
2. Insertion of batteries with incorrect polarities (+, —).

[1] Auto-accompaniment by the Casio Chord System (One-finger Method)
The Casio Chord system has been developed so you can play the four main types of chords more easily.
Playing of the chords is simplified as shown below:
Pressing one of the accompaniment keyboard keys produces a major chord corresponding to that note.
Simultaneously pressing any key to the right (two keys at the same time) results in a minor chord, Simi-
larly, pressing one more key to the right (three keys in all) produces a seventh chord, and pressing the
fourth key to the right (four keys in all) creates a minor seventh chord.
(Example)
C (C major chord) — Press®.
Cm (C minor chord) — Press®, @together.
Ci(C seventh chord) — Press ®,@,®together.
Cmz(C minor seventh chord) — Press@®, ®@, @, Dtogether.
* Not only @,@and@, but any black or white keys can be used as long as they are to the right of @.

The
Envelope
Curve,
Controlled
by
“Attack”,
Decay",
and
“Sustain”.
Every
sound
has
its
own
specific
variations
over
time.
That
is
to
say,
both
the
volume
and
the
tone
color
change
along
with
time
from
the
starting
point
of
the
sound
until
it
dies
out
completely,
Take
a
guitar,
for
example.
You
will
realize
that
volume
and
tone
color
differ
considerably
between
the
momenta
String
is
plucked
and
the
moment
just
before
the
sound
fades
away.
When
this
change
over
time
is
expressed
in
the
form
of
2
graph,
you
get
what
is
called
an
“envelope
curve"
or
just
“envelope”
for
short.
The
MT-400V
has
controls
for
“attack”
“decay”
and
“sustain”
which
allow
you
to
regulate
the
variation
of
the
harmonics
over
time®.
thus
providing
further
control
over
tone
color.
*
As
shown
in
the
illustration,
the
envelope
determines
which
har-
monics
are
heard
at
what
time.
For
example,
after
attack
is
com-
pleted
(the
ee
I
has
peaked),
the
sound
contains
the
greatest
number
of
harmonics
(f
—5f
in
our
case).
Then
after
decay
time
is
over
and
sustain
level
is
reached,
the
sound
will
only
contain
harmonics
f—3f.
*
Adding
a
‘‘Wah-Wah"
Effect
to
a
Sound
While
the
envelope's
attack,
sustain
and
decay
determine
the
change
in
tonal
color
from
the
time
the
sound
starts
to
be
heard
until
it
fades
away,
the
so-called
“wah-wah”
effect
causes
a
sort
of
grow!
by
changing
tone
color
rapidly
and
periodically,
*
Since
the
MT-400V
controls
the
inclusion
of
harmonics
in
a

® Attack Control
Determines
the
period
of
time
from
when
you
press
a
key
to
the
point
where
the
amount
of
harmonics
reaches
its
peak.
(This
peak
level
is
determined
by
the
“cutoff
control”)
As
the
control
approaches
10
(max.),
this
period
becomes
longer,
ie.,
the
amount
of
harmonics
rises
more
slowly
to
the
peak.
@ Decay Control
Determines
the
period
of
time
from
the
point
where
the
amount
of
harmonics
peaks
to
the
point
where
an
amount
of
harmonics
determined
by
“sustain
level”
is
maintained.
As
the
control
approaches
10
(max.),
this
period
becomes
longer,
Le.,
the
amount
of
harmonics
decreases
more
slowly.
@ Sustain Level Control
Determines
the
amount
of
harmonics
maintained
while
you
press
the
key
after
decay
time
(-*
fig.).
As
the
control
approaches
10
(max,),
the
amount
is
increased.
®Cutoff Control
Cuts
off
some
of
the
harmonics
in
the
series
which
constitutes
the
sound
material.
As
the
control
is
slid
away
from
10,
higher
harmonics
begins
to
be
cut
off,
produc-
ing
a
milder
sound.
Also
determines
the
uppermost
point
to
which
the
amount
of
harmonics
rises
after
the
attack
time
(~

(Resonance Control
Puts
emphasis
on
harmonics
near
the
point
(or
frequency)
determined
by
the
“cutoff”,
and
gives
various
nuances,
for
instance
a
nasal
timbre.
As
the
control
approaches
10,
the
degree
of
emphasis
is
increased.
®Stereo Chorus/Waw Speed Control
Determines
the
speed
(cycle)
of
the
“waw”
effect.
When
the
stereo

switch
is
on,
the

of
the
