 Turning off the keyboard causes most current settings 
to be cleared. The keyboard will revert to initial settings 
the next time you turn it on.
 This is true for all settings except for sample sound 
protection. Once you turn it on it remains on until you 
turn it off again.While you are using batteries for power, power will turn off 
automatically if you do not perform any operation for about six 
minutes. Auto Power Off is disabled while the AC adaptor is 
being used for power.

turned off automatically during a concert, etc.
1.While holding down bp, turn on power.
Auto Power Off will be disabled.
While you are using the AC adaptor for power, the keyboard 
keys will light to remind you that power is on if you do not 
perform any operation for about six minutes. Power on alert is 
disabled while batteries are being used for power.

4.Press the bs (10-key) [–] key to select the OFF 
setting.
Using headphones cuts off output from the built-in speakers, 
which means you can practice playing even late at night 
without disturbing others.
 Be sure to turn down the volume level before connecting 
headphones.
 Headphones do not come with the Digital Keyboard.
 Use commercially available headphones. See page E-3 for 
information about options.
 Do not listen to very high volume output over 
headphones for long period. Doing so creates the risk 
of hearing damage.
 If you are using headphones that require an adaptor 
plug, make sure you do not leave the adaptor plugged 
in when removing the headphones.Touch Response alters tone volume in accordance with 
keyboard pressure (speed). This provides you some of the 
same expressivity you get on an acoustic piano.
■Sound intensity depends on the speed that keys 
are pressed.
People normally believe that the stronger the pressure applied 
to a piano keyboard, the louder the sound. Actually, however, 
the intensity of the notes played depends on the speed at 
which keys are pressed. Notes are louder when keys are 
pressed quickly, and quieter when keys are pressed slowly. 
Keeping this in mind as you play a keyboard musical 
instrument lets you control note volume without striving to 
apply too much pressure with your fingertips.
■The playability of an acoustic piano
Your Digital Keyboard provides you with key touch that is the 
next best thing to an acoustic piano. Note volume changes 
automatically in accordance with key press speed.

The metronome lets you play and practice along with a steady 
beat to help keep you on tempo.
1.Press 7.
This starts the metronome.
2.Press 7 again to stop the metronome.
You can configure the metronome to use a bell sound for the 
first beat of each measure of the song you are playing.
 You can specify 0, or a value from 2 to 6 as the number of 
beat per measure.
 When playing a built-in song, the beats per measure setting 
(which determines when the bell sounds) is configured 
automatically for the currently selected song.
1.Hold down 7 until the beats per measure 
setting screen appears on the display.
 If you do not perform any operation for a few seconds 
after the beats per measure setting screen appears, the 
display will return to the screen displayed before you 
pressed 
7.
2.Use bs (10-key) to enter the number of beats 
per measure.
 The bell will not sound if you specify 0 for this setting. In 
this case, all beats are indicated by a click sound. This 
setting lets you practice with a steady beat, without 
worrying how many beats there are in each measure.Use the following procedure to change the tempo of the 
metronome.
1.Press bo.
Use y (slower) and t (faster) to change the tempo 
setting. Holding down either button changes the setting at 
high speed.
 Pressing t and y at the same time will initialize the 
tempo setting in accordance with the currently selected 
song or rhythm.
 Pressing 
bo causes the tempo value to flash on the 
display. While the tempo value is flashing, you can use 
bs (10-key) to change it.
Note that you must input leading zeros, so 89 is input 
as 089.
 The tempo value will stop flashing if you do not perform 
any operation for a short while.
The metronome volume setting is changed automatically with 
the volume level of the currently selected Auto 
Accompaniment or song. The metronome volume cannot be 
adjusted independently.
 For information about changing the Auto Accompaniment 
volume, see page E-42.
 For information about changing the song volume, see page 
E-29.
 You cannot adjust the balance between the metronome 
and note volume during Auto Accompaniment and built-in 
tune play.

Sampling Sounds and Playing Them on the Digital 
Keyboard
You can sample a sound from a microphone, a portable audio 
player, or other device, and then play the sound with keyboard 
keys. For example, you could sample the bark of your dog 
and then use the sound in a melody. You also can sample and 
use passages from a CD. The sampling feature is a great way 
to create new sounds that are highly creative.
 Before connecting, make sure that the Digital 
Keyboard, external devices, and/or the microphone all 
are turned off.
1.Connect a microphone or external device to the 
Digital Keyboard.
 You also could connect a commercially available 
microphone.
 Connection of an external device requires commercially 
available connecting cords, supplied by you. Connecting 
cords should have a stereo mini plug on one end and a plug 
that matches the configuration of the external device on the 
other end.
2.Turn down the volume levels of the external 
device and the Digital Keyboard.
3.Turn on the external device or microphone, and 
then turn on the Digital Keyboard.
 When using a microphone, adjust the input volume 
level with 
3.
 It will take a few seconds after you turn on the Digital 
Keyboard before you will be able to use the microphone.
 Sampled sounds are recorded in monaural.
