Problem
Possible Cause and Solution
When the instrument is turned on or off, a popping
sound is temporarily produced.
This is normal and indicates that the instrument is receiving electrical
power.
When using a mobile phone, noise is produced.
Using a mobile phone in close proximity to the instrument may produce
interference. To prevent this, turn off the mobile phone or use it further
away from the instrument.
Noise is heard from the instrument’s speakers or
headphones when using the instrument with an
application on a smart device.
When you use the instrument along with the application on your smart
device, we recommend that you set “Airplane Mode” to “ON” on your
smart device in order to avoid noise caused by communication.
There is no sound even when the keyboard is
played or when a Song or Style is being played
back.
Check that nothing is connected to the [PHONES/OUTPUT] jack on the
rear panel. When a set of headphones is plugged into this jack, no
sound is output.
Check the Local Control on/off setting. (See page 62 Function 040.)
Make sure Local Control is set to ON.
The instrument does not respond when the instru-
ment is operated.
Is Storage Mode set to ON? Make sure Storage Mode is set to OFF;
refer to “Storage” on page 63 (Function 059).
Playing keys in the right hand area of the keyboard
does not produce any sound.
When using the Dictionary function (page 49), the keys in the right hand
area are used only for entering the chord root and type.
Not all of the voices seem to sound, or the sound
seems to be cut off.
The instrument is polyphonic up to a maximum of 48 notes—including
Dual voice, Split Voice, Style, Song, and Metronome.
Notes exceeding this limit will not sound.
The harmony doesn’t sound.
The method of sounding the Harmony effect (001–026) differs depend-
ing on the selected type. For Types 001–005, turn the Auto Accompani-
ment on and play it by pressing a chord in the auto accompaniment
section of the keyboard, then play some keys in the right-hand side to
produce the Harmony effect. You can play the types 006–026 without
turning Auto Accompaniment on. However, it is necessary to play two
notes simultaneously for Types 006–012.
The Style or Song does not play back when the
[START/STOP] button is pressed.
Is External Clock set to ON? Make sure External Clock is set to OFF;
refer to the function settings on page 62 (Function 041).
The ACMP ON indicator does not appear when the
[ACMP ON/OFF] button is pressed.
•
Always press the [STYLE] button first when you are going to use any
Style-related function.
•
The ACMP ON indicator does not appear when the Duo mode is on.
The Style does not sound properly.
Make sure that the Style Volume (page 61 Function 016) is set to an
appropriate level.
Is the Split Point set to an appropriate key for the chords you are play-
ing? Set the Split Point to an appropriate key (page 60 Function 003).
Is the “ACMP” indicator showing in the display? If it is not showing, press
the [ACMP ON/OFF] button so that it does show.
The Style does not sound as you play a chord.
If the Fingering Type (Function 017; page 61) is set to Multi, the following
conditions will occur.
•
The auto accompaniment will sometimes not change when related
chords are played in sequence (e.g., some minor chords followed by
the minor seventh).
•
Two-note fingerings will produce a chord based on the previously
played chord.
•
Playing two same root keys in the adjacent octaves produces accom-
paniment based only on the root.
The footswitch (for sustain) seems to produce the
opposite effect. For example, pressing the foot-
switch cuts off the sound and releasing it sustains
the sounds.
The polarity of the footswitch is reversed. Make sure that the footswitch
plug is properly connected to the [SUSTAIN] jack before turning on the
power.
The sound of the voice changes from note to note.
This is normal. The AWM tone generation method uses multiple record-
ings (samples) of an instrument across the range of the keyboard; thus,
the actual sound of the voice may be slightly different from note to note.
