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)

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.

• 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.

Remove the battery

compartment cover.

Load 6 AA-size batteries

into the battery

compartment.

• Make sure that the

positive (+) and negative

(–) ends are facing

correctly.

Insert the tabs on the

battery compartment

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.

■

Any of the following symptoms indicate low battery power.

Replace batteries as soon as possible whenever any of

the following occurs.

• Instrument does not turn on

• Display that is flickering, dim, or difficult to read

• Abnormally low speaker/headphone volume

• Distortion of sound output

• Occasional interruption of sound when playing at high

volume

• Sudden power failure when playing at high volume

• Flickering or dimming of the display when playing at

high volume

• Continued sound output even after you release a key

• A tone that is totally different from the one that is

selected

• Abnormal rhythm pattern and Song Bank play

Connect the keyboard to an audio equipment using a

commercially available connecting cord with a standard plug

on one end and two PIN plugs on the other end. In this

configuration, you normally set the input selector of the audio

equipment to the terminal (usually marked AUX IN or

something similar) where the cord from the keyboard is

connected. See the user documentation that comes with your

audio equipment for full details.

BASS PIANO

PERCUSSION (No.99)

• PERCUSSION (Tone 99) assigns 35 percussion sounds to

the keyboard as shown below. The sounds assigned to each

key are indicated above the keyboard.

❚

NOTE

• Always enter two digits for the tone number. If you enter only

one digit, the display will automatically return to the previous

tone number setting after a few seconds.

• If you change the tone setting while a keyboard key is

depressed, the tone does not change until you release the key

and press a keyboard key again.

• With certain tones (such as percussion sounds and sound

effects), there may be very little or no change at all in the pitch,

no matter which keyboard key you press.

• If you input the wrong first digit for a tone number, you can

return to the previous setting by pressing the TONE button.

Keyboard split tones

Some of the preset tones split the keyboard and assign two

or more sounds. With such a preset tone, the sound produced

depends on what position of the keyboard you play. For

example, BASS/PIANO (tone 90) puts BASS on the left and

PIANO on the right of the keyboard.

BASS/PIANO (No.90)

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 auto-

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

the rest of this manual.
