Troubleshooting
Problem
Possible Cause and Solution
When the EZ-150 is turned on or off, a pop-
ping sound is temporarily produced.
This is normal and indicates that the EZ-150 is receiving electrical power.
When using a mobile phone, noise is pro-
duced.
Using a mobile phone in close proximity to the EZ-150 may produce in-
terference. To prevent this, turn off the mobile phone or use it further
away from the EZ-150.
The sound of the voices or rhythms seems
unusual or strange.
The battery power is too low. Replace the batteries. (See page 10.)
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 that Light Guide is turned on in the Lesson mode.
When playing back one of the Pianist styles
(#81 - #00), the rhythm cannot be heard.
This is normal. The Pianist styles have no drums or bass — only piano
accompaniment. The accompaniment of the style can only be heard
when accompaniment is set to ON and keys are played in the auto ac-
companiment area of the keyboard.
The auto accompaniment doesn’t turn on,
even when pressing the [ACCOMPANI-
MENT ON/OFF] button.
Make sure the Style mode is active before using the auto accompani-
ment. Press the [STYLE] button to enable style operations.
Not all notes are heard when playing a num-
ber of notes simultaneously.
Too many keys are pressed at the same time. The EZ-150 is polyphonic
up to a maximum of 16 notes.
Playing keys in the right hand section of the
keyboard does not produce any sound.
When using the Dictionary function (page 43), the keys in the right hand
section are used only for entering the chord root and type.
The accompaniment does not sound proper-
ly.
Make sure that the Accompaniment Volume (page 49) is set to an appro-
priate level.
The Multi Pad sound is cut off or sounds un-
usual.
The EZ-150 is polyphonic up to a maximum of 16 notes. If a style or song
is playing back at the same time a Multi Pad is played, some notes/
sounds of the Multi Pad may be omitted (or “stolen”) from the accompa-
niment or song.
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.
The Light Guide does not match the keys ac-
tually played.
When auto accompaniment is on, the Light Guide shows the specific
notes of the chords you play in the auto accompaniment area of the key-
board. If you play a single finger chord, or an inversion of a chord, the
corresponding chord will be appropriately shown — even if the lighting
keys do not exactly match the pressed keys.
