Using the music rest
Connecting Headphones or 
External Audio Equipment
Any pair of stereo headphones with a 1/4” stereo 
phone plug can be plugged in here for convenient 
monitoring. The speakers are automatically shut off 
when a plug is inserted into this jack.
The PHONES/OUTPUT jack also functions as an 
external output. You can connect the PHONES/OUT-
PUT jack to a keyboard amplifier, stereo system, 
mixer, tape recorder, or other line-level audio device 
to send the instrument’s output signal to that device.
Connecting a Footswitch to the 
SUSTAIN jack
You can produce a natural sustain as you play by 
pressing an optional Footswitch plugged into the 
[SUSTAIN] jack. 
Turning the Power On/Off
Turn down the [MASTER VOLUME] control to 
“MIN” then press the [ ] (Standby/On) switch to 
turn on the power. While playing the keyboard, adjust 
the [MASTER VOLUME] control. To turn off the 
power, press the [ ] (Standby/On) switch again for 
a second.
While playing the keyboard, use the [MASTER VOL-
UME] 
control
 to adjust the volume to an appropriate 
level.
• Failure to set the Battery Type may shorten the amount of 
the battery life. Make sure to set the Battery Type correctly. 
• Do not use the instrument/device or headphones for a long 
period of time at a high or uncomfortable volume level, 
since this can cause permanent hearing loss. If you experi-
ence any hearing loss or ringing in the ears, consult a phy-
sician.
• Before connecting the instrument to other electronic com-
ponents, set all volume levels to the minimum, then turn 
off the power for all components.
NOTICE
Insert the music rest 
into the slots as shown.
CAUTION
• When the instrument’s sound is output to an external 
device, first turn on the power to the instrument, then to 
the external device. Reverse this order when you turn the 
power off.
• Make sure that the footswitch plug is properly connected to 
the SUSTAIN jack before turning on the power.
• Do not press the footswitch while turning the power on. Doing 
this changes the recognized polarity of the footswitch, result-
ing in reversed footswitch operation.
• When using a power adaptor, even when the power is off, a 
small amount of electricity is still being consumed by the 
instrument. When you are not using the instrument for a 
long time, make sure to unplug the AC power adaptor from 
the wall AC outlet.
