Connecting Headphones (Figure 1)
Connecting headphones cuts off output from the keyboard’s built-in speakers, so you
can play even late at night without disturbing anyone.
Audio Equipment (Figure 2)
Connect the keyboard to an audio equipment using a commercially available con-
necting 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.
Musical Instrument Amplifier (Figure 3)
Use a commercially available connecting cord to connect the keyboard to a musical
instrument amplifier.
Note
•Be sure to use a connecting cord that has standard plugs on the ends you connect to
the keyboard and amplifier.

Power Supply
This keyboard can be powered by current from a standard household wall outlet
(using the specified AC adaptor) or by batteries. Always make sure you turn the
keyboard off whenever you are not using it.
Using batteries
Always make sure you turn off the keyboard before loading or replacing batteries.
To load batteries
1. Remove the battery compartment cover.
2. Load 6 AA-size batteries into the battery compartment.
•Make sure that the positive (+) and negative (–) ends
are facing correctly.
3. Insert the tabs on the battery compartment cover into the
holes provided and close the cover.
The keyboard may not function correctly if you load or replace batteries with power
turned on. If this happens, turning the keyboard off and then back on again should
return functions back to normal.
Important Battery Information
The following shows the approximate battery life provided by different battery
types.
•Standard battery life: Approximately 1 hour (SUM3/R6P)
Approximately 4 hours (AM3/LR6)
Both of the above values are standard battery life at normal temperature, with the
keyboard volume at a 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.
•Dim power supply indicator
•Instrument does not turn on
•Dim, difficult to read display
•Abnormally low speaker/headphone volume
•Distortion of sound output
•Occasional interruption of sound when playing at high volumes
•Sudden power failure when playing at high volumes
•Dimming of the display when playing at high volume
•Abnormal rhythm pattern and demo tune play
•Dimming of keyboard lights when notes sound
•Loss of power, sound distortion, or low volume when playing from a con-
nected computer or MIDI device

Important!
Improper handling of batteries can cause them to burst and leak, which creates the
danger of personal injury or damage due to contact with battery acid. Be sure to note the
following important precautions.
•Always make sure that the positive (+) and negative (–) poles are facing correctly as
indicated inside the battery compartment.
•To avoid damage caused by leaking batteries, be sure to remove batteries from the
keyboard whenever you leave it unattended for long periods (such as when leaving
on a trip).
•Never mix batteries of different types.
•Never mix old batteries with new ones.
•Never discard batteries by incinerating them, do not allow their poles to be shorted
(connected to each other), never take batteries apart, and do not expose batteries to
direct heat.
•Replace batteries as soon as possible after any sign they are getting weak.
•Never attempt to recharge batteries.
 Using the AC Adaptor
Make sure that you use only the AC adaptor specified for this keyboard.
Specified AC Adaptor: AD-5
Also note the following important warnings and precautions when using the AC
adaptor.
Warning!
•Take care to avoid any damage to or breakage of the power cord. Never place any
heavy objects on the power cord or expose it to direct heat. Doing so creates the
danger of power cord damage, fire, and electrical shock.
•Use only the specified AC adaptor. Use of another type of adaptor creates the danger
of fire and electrical shock.

Caution!
•For safety sake, be sure to unplug the AC adaptor from the wall outlet whenever
leaving the keyboard unattended for a long time (such as when leaving on a trip).
•Always turn off the keyboard and unplug the AC adaptor from the wall outlet when
you are not using the keyboard.
Important!
•Make sure that the keyboard is turned off before connecting or disconnecting the AC
adaptor.
•Using the AC adaptor for a long time can cause it to become warm to the touch. This
is normal and does not indicate malfunction.
Auto Power Off
When you are using battery power, keyboard power turns off automatically when-
ever you leave it on without performing any operation for about 6 minutes. When
this happens, move the POWER/MODE selector to the OFF position and then back to
NORMAL, CASIO CHORD, or FINGERED to turn power back on.
Note
•Auto Power Off is disabled (it does not function) when you are using the AC adaptor
to power the keyboard.
Power On Alert
Keyboard keys light to alert you if you leave power on and do not perform any
operation for about 6 minutes. Note that keys light only, and no sound is produced.
When this happens, press any button or keyboard key to clear the power on alert.
Note
•Power on alert operates only when you are powering the keyboard using the AC
adaptor. It does not operate when you are using batteries.
To disable Auto Power Off and power on alert
Hold down the TONE button while turning on the keyboard to disable Auto Power
Off and power on alert.
•When these functions are turned off, the keyboard does not turn off automatically
and no alert is performed no matter how long it is left with no operation being
performed.
•Auto Power Off and power on alert are enabled again when you manually turn off
power and then turn it back on again.

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)
BASS PIANO
PERCUSSION (No.99)
•PERCUSSION (tone 99) assigns 35 percussion sound to the keyboard as illustrated
below. The sound assigned to each key are indicated above the keyboard.
