This instrument features several Reverb Types that 
add extra depth and expression to the sound to create a 
realistic acoustic ambience. Although the appropriate 
Reverb Type is called up automatically when you

You can shift the pitch of the entire keyboard up or 
down in semitones in order to facilitate playing in dif-
ficult key signatures, or to easily match the pitch of 
the keyboard to the range of a singer or other instru-
ments. For example, if “+5” is selected, playing key C 
produces pitch F, letting you play a song of F major as 
though it were in C major.
To transpose the pitch down:
While holding down [DEMO/SONG] and [METRO-
NOME/RHYTHM], press a key between F#3 (-6) and 
B3 (-1). 
To transpose the pitch up:

NOME/RHYTHM], pres s a key between C#4 (+1) 
and F #4 (+6). 
To restore the original pitch:
While holding down [DEMO/SONG] and [METRO-
NOME/RHYTHM], pr ess the C4 key. You can fine tune the pitch of the entire instrument in 
approximately 0.2 Hz increments. This lets you match 
the keyboard pitch finely to that of other instruments 
or CD music. 
To lower the pitch:
While holding down [DEMO/SONG] and [METRO-
NOME/RHYTHM], press the C
#0 key repeatedly to 
lower the pitch in approximately 0.2 Hz increments.
To raise the pitch:
While holding down [DEMO/SONG] and [METRO-

raise the pitch in approximately 0.2 Hz increments.
To reset the pitch to the default (A3 = 440 Hz):

ProblemPossible Cause and Solution
The instrument does not turn on. The instrument has not been plugged in properly. Securely insert the female plug into 
the jack on the instrument, and the male plug into a proper AC outlet (page 7).
The instrument is automatically turned off even if 
no operation is done. This is normal. This occurs due to the Auto Power Off function (page 19).
Noise is heard from the speakers or head-
phones. The noise may be due to interference caused by the use of a mobile phone in close 
proximity to the instrument. Turn off the mobile phone, or use it further away from the 
instrument.
The overall volume is low, or no sound is heard. The Master Volume is set too low; set it to an appropriate level using the [MASTER 
VOLUME] slider (page 7).
Make sure a pair of headphones is not c
onnected to the headphones jack (page 7).
Make sure that Local Control is ON. For details, refer to “MIDI Reference” (page 4) on 
the website. 
The pedal has no effect. The pedal cable/plug may not be properly connected. Make sure to securely insert the 
pedal plug into the [SUSTAIN] or [PEDAL UNIT] jack (page 8).
The footswitch (for sustain) seems to produce 
the opposite effect. For example, pressing the 
footswitch cuts off the sound and releasing it 
sustains the sounds. The polarity of the footswitch is reversed because the footswitch was pressed when the 
power was turned on. Turn off the power and turn it on again to reset the function. Make 
sure to not press the footswitch when turning the power on.
