When using a mobile phone, noise is produced. Using a mobile phone in close proximity to the DGX-500/300 may produce interference. To prevent this, turn off the mobile phone or use it further away from the DGX-500/300. There is no sound even when the keyboard is played or when a song 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. (See page 86.)

Make sure that the Split Point (page 49) is set to an appropriate value. When playing back one of the Pianist styles (#124 - #135), the rhythm cannot be heard. This is normal.

Do not press the pedal while turning the power on. The sound of the voice changes from note to note. The AWM tone generation method uses multiple recordings (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. 89

Troubleshooting
Problem
Possible Cause and Solution
When the DGX-500/300 is turned on or off, a pop-
ping sound is temporarily produced.
This is normal and indicates that the DGX-500/300 is receiving elec-
trical power.
When using a mobile phone, noise is produced.
Using a mobile phone in close proximity to the DGX-500/300 may
produce interference.
To prevent this, turn off the mobile phone or
use it further away from the DGX-500/300.
There is no sound even when the keyboard is
played or when a song 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. (See page 86.)
Playing keys in the right hand section of the key-
board does not produce any sound.
When using the Dictionary function (page 50), the keys in the right
hand section are used only for entering the chord root and type.
The sound of the voices or rhythms seems unusu-
al or strange.
The battery power is too low.
Replace the batteries.
(See page 10.)
The song or style does not start playback.
Check the External Clock.
(See page 88.)
The auto accompaniment doesn’t turn on, even
when pressing the [ACMP] button.
Make sure the Style mode is active before using the auto accompa-
niment.
Press the [STYLE] button to enable style operations.
The accompaniment does not sound properly.
Make sure that the Accompaniment Volume (page 46) is set to an ap-
propriate level.
Make sure that the Split Point (page 49) is set to an appropriate value.
When playing back one of the Pianist styles (#124
- #135), the rhythm cannot be heard.
This is normal.
The Pianist styles have no drums or bass — only pi-
ano accompaniment.
The accompaniment of the style can only be
heard when accompaniment is set to ON and keys are played in the
auto accompaniment area of the keyboard.
Not all of the voices seem to sound, or the sound
seems to be cut off.
The DGX-500/300 is polyphonic up to a maximum of 32 notes.
If the
Dual voice or Split voice is being used and a style or song is playing
back at the same time, some notes/sounds may be omitted (or “sto-
len”) from the accompaniment or song.
A strange “flanging” or “doubling” sound occurs
when using the DGX-500/300 with a sequencer.
(This may also sound like a “dual” layered sound
of two voices, even when Dual is turned off.)
When using the accompaniment with a sequencer, set MIDI Echo (or
the relevant control) to “off.”
(Refer to the owner’s manual of your par-
ticular device and/or software for details.)
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 foot-
switch plug is properly connected to the FOOT SWITCH jack before
turning on the power.
Do not press the pedal while turning the power on.
The sound of the voice changes from note to note.
The AWM tone generation method uses multiple recordings (sam-
ples) of an instrument across the range of the keyboard; thus, the ac-
tual sound of the voice may be slightly different from note to note.
