EZ-250i Owner’s Manual
Troubleshooting
Problem
Possible Cause and Solution
When the EZ-250i is turned on or off, a popping
sound is temporarily produced.
This is normal and indicates that the EZ-250i is receiving electrical
power.
When using a mobile phone, noise is produced.
Using a mobile phone in close proximity to the EZ-250i may produce
interference. To prevent this, turn off the mobile phone or use it fur-
ther away from the EZ-250i.
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 or PC Mode on/off. (See page 57, 58.)
Playing keys in the right hand area of the keyboard
does not produce any sound.
When using the Dictionary function (page 42), the keys in the right
hand area 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 auto accompaniment doesn’t turn on, even
when pressing the [ACMP ON/OFF] button.
Make sure the Style mode is active before using the auto accompa-
niment. Press the [STYLE] button to enable style operations.
The style or song does not play back even when
pressing the [START/STOP] button.
Check the External Clock on/off. (See page 57.)
The style or song does not sound properly.
Make sure that the Style Volume or Song Volume (page 39) is set to
an appropriate level.
When playing back one of the Pianist styles (#93 -
#100), 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 EZ-250i 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 “stolen”)
from the accompaniment or song.
A strange “flanging” or “doubling” sound occurs
when using the EZ-250i with a sequencer. (This
may also sound like a “dual” layered sound of two
voices, even when Dual is turned off.)
When using the style with a sequencer, set MIDI Echo (or the relevant
control) to “off.” (Refer to the owner’s manual of your particular de-
vice 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 SUSTAIN jack before turning
on the power.
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.
