Be sure to use a connecting cord that has a stereo
standard plug on the end you connect to the keyboard, and
a connector that provides dual channel (left and right) input
to the amplifier to which you are connecting. The wrong
type of connector at either end can cause one of the stereo
channels to be lost.
1 SUSTAIN/ASSIGNABLE JACK Terminal
J Sustain Pedal
With piano tones, depressing the pedal causes notes to
linger, much like a piano’s damper pedal.
With organ tones, depressing the pedal causes notes to
continue to sound until the pedal is released.
J Sostenuto Pedal
As with the sustain pedal function described above,
depressing the sostenuto pedal causes notes to be
sustained.
This difference between a sostenuto pedal and sustain
pedal is the timing. With a sostenuto pedal, you press the
keys and then depress the pedal before you release the
keys. Only the notes that are sounding when the pedal is
depressed are sustained.
J Soft Pedal
Depressing the pedal softens the sound of the notes being
played.

This section provides information on performing basic
keyboard operations.
Playing the Keyboard
To play the keyboard
1. Press the POWER button to turn the keyboard
on.
2. Set the MODE switch to NORMAL.
3. Use the VOLUME slider to set the volume to a
relatively low level.
4. Play something on the keyboard.
Selecting a Tone
This keyboard comes with 137 built-in tones. Use the
following procedure to select the tone you want to use.
To select a tone
1. Find the tone you want to use in the keyboard’s
tone list and note its tone number.
2. Press the TONE button.
1
Indicator appears
3. Use the number buttons to input the three digit
tone number for the tone you want to select.
Example:
To select “032 ACOUSTIC BASS”, input 0, 3 and
then 2.
Always input all three digits for the tone number, including
leading zeros (if any). If you input one or two digits and
stop, the display will automatically clear your input after a
few seconds.
You can also increment the displayed tone number by
pressing [+] and decrement it by pressing [–].
When one of the drum sets is selected (tone numbers 128
through 136), each keyboard key is assigned a different
percussion sound. See page A-3 for details.
Polyphony
The term polyphony refers to the maximum number of notes
you can play at the same time. The keyboard has 24-note
polyphony, which includes the notes you play as well as the
rhythms and auto-accompaniment patterns that are played
by the keyboard. This means that when a rhythm or autoaccompaniment pattern is being played by the keyboard, the
E-18
641A-E-020A
number of notes (polyphony) available for keyboard play is
reduced. Also note that some of the tones offer only 12-note
polyphony.
When rhythm or auto accompaniment is playing, the
number of sounds simultaneously played is reduced.
Digital Sampling
A number of the tones that are available with this keyboard
have been recorded and processed using a technique called
digital sampling. To ensure a high level of tonal quality,
samples are taken in the low, mid, and high ranges and then
combined to provide you with sounds that are amazingly
close to the originals. You may notice very slight differences
in volume or sound quality for some tones when you play
them at different positions on the keyboard. This is an
unavoidable result of multiple sampling, and it is not a sign
of malfunction.
Turning the Key Light System
On and Off
Use the following procedure when you want to turn the key
light system on or off.
Basic Operations
Using the Metronome
The metronome feature of this keyboard produces a bell
sound for the first beat of each measure, followed by click
sounds for each successive beat of the measure. It is the
perfect tool for practicing tunes without accompaniment
(rhythm).
To start the metronome
1. Press the METRONOME button to start
sounding the metronome.
2. Press the BEAT button and then use the
number buttons or [+] and [–] to change the
number of beats per measure.
You can specify the number of beats per measure
as a value from 1 to 6.
To turn the key light system on and off
1. Press the KEY LIGHT button to toggle the key
light system on and off.
The KEY LIGHT pointer disappears when the
key light system is turned off.
The key light system is turned on automatically whenever
you turn on keyboard power.
The bell (indicating the first beat of a measure) does not
sound while one beat per measure is specified. All beats
are indicated by a click sound. This setting lets you practice
with a steady beat, without worrying about how many beats
there are in each measure.
3. Use the TEMPO buttons to set the tempo.
Press to increase the tempo (make if faster) or
to decrease it (make it slower).

Basic Operations
While the tempo value is flashing, you can also use the
number buttons or [+] and [–] to input a three-digit value.
Note that you must input leading zeros, so 90 is input as
090.
Pressing both the and TEMPO buttons at the same
time automatically returns the currently selected rhythm to
its default tempo.
4. To turn off the metronome, press the
METRONOME or START/STOP button.
The metronome is disabled whenever you are using Step 1
or Step 2 of the 3-step lesson.
Starting play of a two-hand tune (Song Bank tunes 70
through 99) or Step 3 of the 3-step lesson while the
metronome is operating or activating the metronome while
either of the two above operations is already in progress
causes the metronome to sound in time with the Auto
Accompaniment played by the keyboard. At this time, the
tempo of the metronome beat changes to that of the default
tempo for the Auto Accompaniment being played.

This keyboard automatically plays bass and chord parts in
accordance with the chords you finger. The bass and chord
parts are played using sounds and tones that are
automatically selected to select the rhythm you are using. All
of this means that you get full, realistic accompaniments for
the melody notes you play with your right hand, creating the
mood of an one-person ensemble.
You can also increment the displayed rhythm number by
pressing [+] and decrement it by pressing [–].
Selecting a Rhythm
This keyboard provides you with 100 exciting rhythms that
