chased the keyboard or with an autho-  
rized CASIO service provider.  
Be careful of the bags around children.  
• Never allow anyone to place the plastic bags  
of the instrument, its accessories, and its  
separately sold options over their heads.  
Doing so may cause suffocation. Particular  
caution is required in homes with small  
children.  
• Replace dead batteries as soon as possible.  
• Never attempt to recharge batteries.  
Transport  
• When transporting the instrument, always  
make sure to unplug the AC adaptor from  
the electrical outlet and confirm that all  
other external connections have been dis-  
connected. Only then should the instrument  
be transported. If the above is not done, the  
cord may be damaged leading to possible  
fire or electrical shock.

Care  
Optional Stand*  
• Whenever caring, make sure to first un-  
plug the AC adaptor from the electrical out-  
let. Also remove the instrument’s batteries  
if battery power is being used.  
• Carefully assemble the stand following the  
assembly instructions that come with it. Se-  
curely tighten all bolts, nuts, and fasteners,  
and make sure that you mount the instru-  
ment correctly onto the stand. Incorrectly  
or insufficiently tightening screws, or in-  
correctly mounting the instrument onto the  
stand can cause the stand to tip over or the  
instrument to fall off the stand, possibly  
leading to injury.  
Location  
• Never locate the instrument in areas sub-  
ject to high humidity or heavy accumula-  
tion of dust. Doing so may cause fire or  
electrical shock.  
• Never locate the instrument in areas sub-  
ject to grease splatters or steam, such as in a  
kitchen or near a humidifier. Doing so may  
cause fire or electrical shock.  
* The stand is available as an option.  
Do not place keyboard on lacquered furniture.  
• The instrument’s silicone rubber feet may  
eventually blacken or scar lacquered sur-  
faces. Use felt cloth pads to insulate the feet  
or preferably use a CASIO musical instru-  
ment stand designed for your keyboard.  
Do not place heavy objects on the instrument.  
• Do not place heavy objects on the instru-  
ment. This may cause the instrument to tip  
over or break resulting in injury.  
Volume  
• Very high volume levels can damage hear-  
ing. Avoid using the instrument at very  
high volume settings for long periods. Con-  
sult with a physician immediately if you  
experience impaired hearing or ringing in  
the ears.  
Liquid Crystal Display (LCD) Precautions  
• Avoid subjecting the keyboard's LCD to  
strong impact, which can crack or break the  
LCD's glass creating the danger of personal  
injury.  
• Should the LCD glass ever crack or break,  
do not allow the liquid inside the LCD to  
come into contact with your skin, which  
can cause inflammation and reddening.  
*Should the LCD liquid get into your  
mouth, immediately wash out your mouth  
with water and then consult a physician.  
*Should the LCD liquid get in your eyes or  
on your skin, immediately flush with wa-  
ter for at least 15 minutes and then consult  
a physician.  
Do not get onto the instrument or stand.*  
• Do not crawl on top of the instrument or its  
optional stand. Particular caution is re-  
quired in homes having small children. This  
may cause the instrument or stand to tip  
over and break resulting in injury.

Accessories and Options  
Use only the accessories and options specified for this keyboard. Use  
of non-authorized items creates the danger of fire, electrical shock,  
and personal injury.  
Audio Equipment (Figure 2)  
Connect the keyboard to a audio equipment using a commercially  
available connecting cord with a standard plug on one end and two  
PIN plugs on the other end. Note that the standard plug you connect  
to the keyboard must be a stereo plug, otherwise you will be able to  
output only one of stereo channels. In this configuration, you nor-  
mally 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.  
Musical Instrument Amplifier (Figure 3)

to a musical instrument amplifier.  
NOTE ❚  
Be sure to use a connecting cord that has a stereo standard plug on the  
end you connect to the keyboard, and a connector that provides dual chan-  
nel (left and right) input to the amplifier to which you are connecting. The  
wrong type of connector at either end can cause one of the stereo chan-  
nels to be lost.  
When connected to a musical instrument amplifier, set the volume of  
the keyboard to a relatively low level and make output volume ad-  
justments using the amplifiers controls.

Polyphony  
The term polyphony refers to the maximum number of notes you can  
play at the same time. The keyboard has 12-note polyphony, which  
includes the notes you play as well as the rhythms and auto-accom-  
paniment patterns that are played by the keyboard. This means that  
when a rhythm or auto-accompaniment pattern is being played by  
the keyboard, the number of notes (polyphony) available for key-  
board 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.  
Digital Sampling  
A number of the tones that are available with this keyboard have  
been recorded and processed using a technique called digital sam-  
pling. To ensure a high level of tonal quality, samples are taken in the  
low, mid, and high ranges and then combined to provide you with  
sounds that are amazingly close to the originals. You may notice very  
slight differences in volume or sound quality for some tones when  
you play them at different positions on the keyboard. This is an un-  
avoidable result of multiple sampling, and it is not a sign of malfunc-  
tion.

Inverted Forms  
There are a number of different ways to play the same chord. A form  
that is different from the basic form but still produces the same chord  
is called an inverted form.”  
Chords are named using upper-case letters from A through G, which  
indicate the root note of the chord. If the root note is a sharp or flat,  
the chord itself is sharp or flat. A chord name may also be followed  
by a degree number or other symbols that indicate certain character-  
istics about the chord.

on the rhythm that was selected, some of the notes that make  
up a chord may be omitted when you play the chord on the

NOTES ❚  
Since the chord fingerings that appear on the display are selected to  
allow chord play within the accompaniment keyboard, inverted chord  
forms (page E-26) are often suggested. Inverted chord forms are useful  
to help you learn how to play chord variations that make it possible to  
move from one chord to another with minimal hand movement. These  
forms come in handy when using FINGERED Auto Accompaniment play.  
While a chord name is on the display, you can press keys on the accom-  
paniment keyboard to find out the fingerings of the same chord with a  
different root.  
You can also scroll through chord names using the [+] and [] buttons.  
Chord fingerings that appear on the display are formed using only the  
keys within the range of the accompaniment keyboard (leftmost 18 keys).  
Chords that cannot be formed using the keys within this range are not  
displayed.

MIDI  
What is MIDI?  
General MIDI  
The letters MIDI stand for Musical Instrument Digital Interface, which  
is the name of a worldwide standard for digital signals and connec-  
tors that makes it possible to exchange musical data between musi-  
cal instruments and computers (machines) produced by different  
manufacturers. MIDI compatible equipment can exchange keyboard  
key press, key release, tone change, and other data as messages.  
Though you do not need any special knowledge about MIDI to use  
this keyboard as a stand-alone unit, MIDI operations require a bit of  
specialized knowledge. This section provides you with an overview  
of MIDI that will help to get you going.  
General MIDI standardizes MIDI data for all sound source types, re-  
gardless of manufacturer. General MIDI specifies such factors as tone  
numbering, drum sounds, and available MIDI channels for all sound  
sources. This standard makes it possible for all MIDI equipment to  
reproduce the same nuances when playing General MIDI data, re-  
gardless of the manufacturer of the sound source.  
Though the sound source of this keyboard is not General MIDI com-  
patible, you can still connect the keyboard to a computer or other  
MIDI equipment to playback General MIDI data that is widely avail-  
able in stores, over computer networks, and from other sources.  
NOTES ❚  
General MIDI data made up of a large number of parts may not play  
correctly on this keyboard.  
MIDI Connections  
MIDI messages are send out through the MIDI OUT terminal of one  
machine to the MIDI IN terminal of another machine over a MIDI  
cable. To send a message from this keyboard to another machine, for  
example, you must use a MIDI cable to connect the MIDI OUT termi-  
nal of this keyboard to the MIDI IN terminal of the other machine. To  
send MIDI messages back to this keyboard, you need to use a MIDI  
cable to connect the other machines MIDI OUT terminal to the MIDI  
IN terminal of this keyboard.  
To use a computer or other MIDI device to record and playback the  
MIDI data produced by this keyboard, you must connect the MIDI  
IN and MIDI OUT terminals of both machines in order send and re-  
ceive data.  
You will have most success playing back General MIDI data that has  
few parts and is made up of data on channels 1, 2, 3, 4, and 10.  
Messages  
There is a wide variety of messages defined under the MIDI stan-  
dard, and this section details the particular messages that can be sent  
and received by this keyboard.  
NOTE ON/OFF  
This message sends data when a key is pressed (NOTE ON) or re-  
leased (NOTE OFF).  
A NOTE ON/OFF message include a note number (to indicate note  
whose key is being pressed or released) and velocity (keyboard pres-  
sure as a value from 1 to 127). NOTE ON velocity is always used to  
determine the relative volume of the note. This keyboard does not  
receive NOTE OFF velocity data.  
Whenever you press or release a key on this keyboard, the correspond-  
ing NOTE ON or NOTE OFF message is sent by constant velocity  
from the MIDI OUT terminal.

NOTE ❚  
The pitch of a note depends on the tone that is being used, as shown in  
the Note Table on page A-1. Whenever this keyboard receives a note num-  
ber that is outside its range for that tone, the same tone in the nearest  
available octave is substituted.  
MIDI Channels  
MIDI allows you to send the data for multiple parts at the same time,  
with each part being sent over a separate MIDI channel. There are 16  
MIDI channels, numbered 1 through 16, and MIDI channel data is  
always included whenever you exchange data (key press etc.)  
Both the sending machine and the receiving machine must be set to  
the same channel for the receiving unit to correctly receive and play  
data. If the receiving machine is set to Channel 2, for example, it re-  
ceives only MIDI Channel 2 data, and all other channels are ignored.  
With this keyboard, messages received over MIDI Channels 1, 2, 3, 4,  
and 10 can be used for multi-timbre play of up to five different in-  
strument parts. The tone and volume settings for these five channels  
must be controlled by messages sent from an external device.  
When sending operation of this keyboard to an external device, Chan-  
nel 1 should be selected as the MIDI send channel.  
PROGRAM CHANGE  
This is the tone selection message. PROGRAM CHANGE can con-  
tain tone data within the range of 0 to 127.  
A PROGRAM CHANGE message (0 to 99) is sent out through this  
keyboards MIDI OUT terminal whenever you manually change its  
tone number. Receipt of a PROGRAM CHANGE message from an  
external machine changes the tone setting of this keyboard (page E-  
31).  
This keyboard can send tone data within the range of 00 to 99 and  
receive tone data within the range of 0 to 127.  
PITCH BEND  
This message carries pitch bend information for smoothly sliding the  
pitch upwards or downwards during keyboard play. This keyboard  
does not send pitch bend data, but is can receive such data.
