Power Supply

Prepare a household power outlet or batteries.

IMPORTANT!

• Be sure to comply with the “Safety Precautions” provided
in this manual. Incorrect use of this product creates the risk
of electric shock and fire.

• Always make sure that the Digital Keyboard is turned off
before plugging in or unplugging the AC adaptor, or before
loading or removing batteries.

Using a Household Power Outlet

Make sure that you use only the AC adaptor specified for
this keyboard. Use of a different type of AC adaptor can cause
malfunction.

Specified AC Adaptor: AD-E95100L (JEITA Standard plug)

Household power outlet

IMPORTANT!

• The AC adaptor will become warm to the touch after very
long use. This is normal and does not indicate malfunction.

• To prevent breaking of the wire, take care to avoid putting
any type of load on the power cord.

No bending! No winding!

• Never insert metal, pencils, or any other objects into the
product's 9.5V DC terminal. Doing so creates the risk of
accident.

Using Batteries

You can use six AA-size batteries for power.

• Use alkaline or zinc-carbon batteries. Never use oxyride or
any other nickel based batteries.

Open the battery cover on the bottom of the Digital Keyboard,
load the batteries, and then close the cover.

• Take care to ensure that the positive (+) and negative (–)
ends of the batteries are facing correctly.

1.

Remove the battery
compartment cover.

cover into the holes
provided and close the
cover.

Important Battery Information

■

The following shows the approximate battery life.

Alkaline batteries .................................. 4 hours

Zinc-carbon batteries ............................ 1 hour

The above value is standard battery life at normal
temperature, with the keyboard volume at medium
setting. Temperature extremes or playing at very loud
volume settings can shorten battery life.

Polyphony

The term polyphony refers to the maximum number of notes
you can play at the same time. This keyboard has 12-note
polyphony, which includes the notes you play as well as the
rhythms and auto-accompaniment patterns that are played
by the keyboard. This means that when a rhythm or auto­accompaniment pattern is being played by the keyboard, the
number of notes (polyphony) available for keyboard play is
reduced. Also note that some of the tones offer only 6-note
polyphony.

• When rhythm or auto accompaniment is playing, the
number of sounds simultaneously played is reduced.

• Though you can sound up to 12 notes at one time, only the
last four keyboard keys pressed light up.

Other Useful Functions

To change the key of the keyboard

The transpose feature of this keyboard lets you raise or lower
its key in semitone increments. This means you can easily
match to suit someone’s voice, and you can eliminate sharps
and flats from music making it easier to play.

1.

While in any mode besides the Song Bank Mode
(indicated when the SONG BANK indicator is
lit), hold down the TONE button and press the
RHYTHM button.

• Perform step 2 within five seconds after performing
step 1.

NOTE

• If you leave the transpose screen on the display for about five
seconds without doing anything, the screen is automatically
cleared.

• You cannot change the transpose setting while the keyboard is
in the Song Bank Mode.

• In step 2 of the above operation, you could also use the number
buttons 0 to 5 to specify C through F.

• Pressing both of the TEMPO/VALUE buttons (
same time returns the transpose setting to C(0).

• The transpose setting is automatically set to C(0) whenever
you turn keyboard power on.

• The transpose setting is automatically set to C(0) whenever
you press the SONG BANK button.

• The pitch of a transposed note depends on the tone you are
using. If the transpose operation causes a note to exceed the
range of the tone you are using, the same note in the highest
octave of the tone’s range is substituted.

• The transpose operation does not affect tone number 99
(PERCUSSION) or auto-accompaniment rhythms.

Using auto-accompaniment

This keyboard features 50 accompaniment patterns that let
you add full accompaniments to your performances
automatically. With auto-accompaniment, part of the
keyboard is reserved as an accompaniment keyboard. As you
play your chords on the accompaniment keyboard, the
accompaniment pattern adjusts automatically to follow the
progression you play.
You get a choice between two different methods for chord
play. FINGERED lets you play chords as you normally do,
while CASIO CHORD makes it possible to play fully formed
chords with one finger.

About the accompaniment keyboard

The lower (left) 1.5 octaves are reserved for use as an
accompaniment keyboard whenever you select CASIO
CHORD or FINGERED with the POWER/MODE selector.
The panel above the accompaniment keyboard keys is marked
with the names of the notes they play. The remainder of the
keyboard (the part that is not included in the accompaniment
keyboard) is called the melody keyboard. Please be sure to
remember these terms, because they will be used throughout

• If you play one or two notes only in the left hand, or three
notes that do not make up a recognizable chord formation,
no sound will be produced. The FINGERED mode requires
a conventional three or four-note chord formation to
produce an auto-accompaniment. Also, note that auto­chords only work in conjunction with rhythm patterns, and
not independently of them.

❚

NOTE

• The above examples show only one of the possible fingerings
for each chord. Note that you can play the notes that form a
chord in any combination. Each of the following fingerings for
example, produces the same C chord.

Using 3-Step Lesson System

Even individuals who cannot play the keyboard at all can
follow along with the 100 built-in Song Bank tunes with the
ONE KEY PLAY buttons. You can also use the 3-Step Lesson
System to learn at your own pace. Play slowly at first until
you are able to play along at normal speed.
Of the 100 built-in tunes, numbers 00 through 83 feature auto­accompaniment (auto-accompaniment tunes), while 84
through 99 are played using both hands (two-hand tunes).

The 3-Step Lesson System can be used with the following 3­step lesson plan to master keyboard play.

Step 1: Master the timing

Pressing the ONE KEY PLAY buttons plays the
melody for an auto-accompaniment tune or the right
hand part for two-hand tunes. In both cases, the auto­accompaniment (the left hand part in the case of two­hand tunes) is played automatically by the keyboard.
In place of the ONE KEY PLAY buttons, you can also
press any key of the keyboard to play the melody or
right hand part. The purpose of this step is to
familiarize yourself with the timing required to play
melody notes.

Step 2: Master the melody

In this step, you use the display to learn which fingers
you should use to play, and the key light system to
learn which keyboard keys to press. You can play at
the pace you want, because the auto-accompaniment
or left hand part waits until you press the correct key.

VALUE buttons ( and ) at the same time to return the
tempo to its initial preset setting.

To play a built-in Song Bank tune

Timing Indicator

The timing indicator helps you become familiar with tunes
you are playing for the first time by indicating the timing of
notes you play on the keyboard. Timing is easier to see when
you use a slow tempo during lesson play.

Using the Timing Indicator

The timing indicator shows the timing of notes contained in
the currently selected part (R or L). Notes are indicated as
two-segment blocks that scroll from the top of the display,
down to the bottom. A note is played when its block reaches
the bottom of the display.

• The above procedure can be used to change the Song Bank
melody tone before starting play or while play is already in
progress.

• You can also change the tone of two-hand tunes (tune numbers
84 to 99). Note however, that selecting a sustainable tone (like
an organ tone) when using 3-Step Lesson Step 1 or Step 2 (in
which accompaniment waits for correct input from you before
proceeding), can cause notes of the auto accompaniment to
be sustained while the keyboard is waiting for your input. If this
happens, play something on the keyboard to stop the sustained
note.
