Damper pedal: Pressing this pedal sustains the
sound even after removing the hands from the
keyboard.
Soft pedal: Pressing this pedal softens the sound,
and also reduces its volume.
* The soft pedal can be used as the sostenuto pedal
by turning on the power while depressing this
pedal.
Sostenuto pedal: Depressing this pedal after
pressing the keyboard and before releasing the keys
sustains the sound of only the keys just played.
+ Sliding key cover
Do not place heavy objects on the sliding key cover
or subject it to severe shocks. Also, the sliding key
cover should be opened and closed gently, using
both hands.

E Advanced Features
1) Programming Mode
The programming mode allows you to change the keyboard's tuning, and temperament, and utilize the various
MIDI capabilities. These programming functions are performed using the panel switches and keyboard, so
please try them after reading and understanding the programming instructions completely.
A. Entering the programming mode
(1) Press the CHORUS switch.
(2) Holding down the CHORUS switch, press the first three tone
selector switches (PIANO1, PIANO2 and E.PIANO).

In this mode, striking the keyboard produces no sound.
(4) Press a TONE SELECTOR switch to select the desired programming
mode.
The correspondence between switches and 6 types of programming
mode is as below:

(2) Press the CLAVI switch so that it flashes to indicate that the
piano is ready to be tuned.

(3) Unlike the other functions in ine programming mode, this one
produces sound so that you can compare the piano's pitch with
another instrument.
«Note: Playing the keyboard when set up this way produces the timbre
selected before entering the programming mode. Tuning is done
using this timbre. If you want to change the timbre, leave the
programming mode (see p. 5), select the new timbre, and repeat
steps (1) and (2).
(4) Press the highest black key to lower the pitch.
Or press the highest white one to raise it.
lt may be necessary to press these key repeatedly to achieve proper
mæ
(5) Leave the programming mode.
«Note: Momentarily turning off the power restores the original pitch.

3) Temperaments
Your Kawai digital piano offers not only equal temperament (the modern standard) but also immediate access
to those popular during the Renaissance and Baroque period.
«Procedure
(1) Make sure that the piano is in the programming mode.
(2) Press the JAZZ ORGAN switch so that it flashes to indicate that
the piano is waiting for a temperament specification.
(3) Press one of the seven white keys at the lower end of the keyboard
to select one of these corresponding temperamenis.
. Equal temperament without the tuning curve
. Mersenne pure temperament
. Pythagorean temperament
. Meantone temperament
. Werckmeister Il temperament
. Kirnberger Ill temperament
. Equal temperament with the tuning curve
“IOook oh mk
(4) Leave the programming mode.
«Note: When the power is first applied or reapplied after a short break,
the piano returns to the modern standard (equal temperament
with the tuning curve = #7).
Key set function is also available at this point. As you know, limitless
modulation of the key became available only after the inventation of
Equal temperament. When we use a temperament except Equal
temperament, we must carefully choose the key signature to play in.
To select the key signature setting, simply press one of the key. For
example, if the tune you are going to play is written in D major, press D
key to set the keys.
Please note that this will only change the "balance" of the tuning, and
the pitch of the keyboard will remain unchanged. Use the TRANSPOSE
control to change the pitch of the whole keyboard.

E Temperament characteristic
+ Equal temperament
This, by far the most popular piano temperament, divides the scale into
twelve equal semitones and has the advantage of producing the same
chords for all transportation.
« Mersenne temperament
This temperament, which eliminates consonances for thirds and fifth, is
still popular for choral music.
+ Pythagorean temperament
This temperament, which uses mathematical ratios to eliminate
consonances for fifth, has problems with chords, but produces a very
beautiful melodic lines.
+ Meantone temperaments
This temperament, which uses a mean between a major and minor
whole tone to eliminate consonances for thirds, was devised to eliminate
the lack of consonances experienced with certain fifth for the Mersenne
pure temperameni. It produces chords that are more beautiful than
those with the equal temperament.
« Werckmeister Il temperament, Kirnberger lll temperament
For key signature with accidentals, this temperament produces the
beautiful chords of the mean tone, but, as the accidentals increase, the
tension increases, and the temperament produces the beautiful
melodies of the Pythagorean temperament. It is used primarily for
classical music written to take advantage of these characteristics.
