3. Connect the plug of the AC adapter to an AC outlet.
Be sure to use an AC outlet of the correct voltage for your adapter.
Using this instrument with batteries
You can use eight AA alkaline or nickelmetal hydride batteries to power this
instrument.
Zinccarbon batteries cannot be used.
Note: Batteries are not included, so please obtain them separately.
Installing batteries

tabs on the battery compartment cover that is
located on the bottom of this instrument to open the cover.
Note: When turning the instrument upside down, place it on a blanket or
similar material to prevent damage to the display, joystick and so on.
3. When inserting the batteries, be
sure to observe the correct polarity (“+” and “”).
Do not mix new and old batteries, or batteries of different types. Failing to
observe this guideline might cause the batteries to leak or burst.
4. Close the battery cover.
Note: To make sure the correct battery level is displayed, make the setting on
this instrument for the type of battery you are using (see page 21 “Setting
the battery type”).
Replacing the batteries
The battery indicator is displayed at the top righthand part of the display.
Note: This indicator will not be displayed while the AC adapter is plugged in.
When the indicator is blinking, this means that the batteries are nearly
depleted, so replace the batteries as soon as possible or connect an AC
adapter to power this instrument.

will function as a damper switch. As with the damper pedal on a piano, you can
use a pedal with this instrument to sustain the notes you play, even after
taking your fingers off the keyboard. You can also make settings for quarter
tone playing. Note: Note that the damper effect does not work on the lower
part. Note: This instrument does not feature a half-damper function.
· Connect a Korg EXP-2 foot controller to control the volume of the keyboard
part (see page 10 “Selecting the keyboard set”).

Troubleshooting
If this instrument is not operating as expected, check the following points.
The instrument will not turn on.
Is the AC adapter plug connected to the AC outlet? Have you pressed the power
button?
The power will not go off.
Did you hold down the power button for a while?
The power turns off by itself.
The auto poweroff function may be enabled.
No sound is heard from the speakers of this instrument when the keys are
played.
Is the instrument’s volume turned up? Is a pair of headphones connected to
this instrument?
The speakers will not produce sound when headphones are connected to this
instrument. The part buttons might all be muted. Is the volume down on the
pedal connected to the FOOT CONTROLLER jack? If sound is not heard when
pressing some keys, you may have exceeded the instrument’s maximum polyphony.
The local control in the SETTING functions should be set to “On”. Are the
speakers set to off? Press the SPEAKER EQ/[SPEAKER OFF] button while holding
down the [SHIFT] button. The keyboard parts might all be muted.
The sound will not stop.
The functions or polarity for the pedal might not be set correctly.
The sound seems to be doubled.
If you are using a DAW, make sure that the local control setting in the
SETTING functions is set to “Off”.
The sound coming from external audio equipment is distorted.
The inputs of the powered monitor speakers and other equipment might be
overloaded. Adjust the volume on this instrument using the VOLUME knob.
The pitch is off.
Is the transpose function set correctly? Has “MasterTuning” in the SETTING
functions been set
correctly, as well as the program’s octave and tune edit parameters? Is the
scale set correctly? See “UpperScaleTyp” (page 22) and “StyleScaleTyp” (page
22) for these settings in the SETTING functions. The quarter tone settings may
be enabled. Check the “Pedal Function” (page 22) in the SETTING functions.
29 Appendix
I hear unwanted noise.
When the volume for a part is raised, the digital signal processing may
overload the signal, which could cause distortion or other noises. This is not
a malfunction. Try lowering the volume on each part button.
You may hear distorted or noisy sounds due to input overload with certain
effects. This is not a malfunction.
In certain electrical environments, you may hear noise due to a ground loop or
other factors.
The pedal switch or expression pedal connected to the FOOT CONTROLLER jack
doesn’t work like it should.
The functions or polarity for the pedal might not be set correctly. See “Pedal
Function” (page 22) and “Pedal Polarity” (page 22) for these settings in the
SETTING functions.
Is the variable range of the expression pedal set correctly? Calibrate as
shown on “Calibrating an expression pedal” (page 28).
I cannot record a user song.
The maximum number of user songs is 999. You may need to delete one (see page
20 “Deleting a user song”.)
MIDI signals sent to/from this instrument and a computer are not being
correctly received.
Is the USB cable connected correctly to the USB TO HOST port?
The instrument does not let me access the MEDIA functions.
Is your USB flash drive correctly plugged in? If the USB flash drive is
correctly plugged in, you should see in the display.
