Troubleshooting
Problem Possible Cause and Solution
When the EZ-20 is turned on or
off, a popping sound is tempo-
rarily produced.
This is normal and indicates that the EZ-20 is receiving electrical
power.
• The volume level is low.
• Tonal quality has degraded.
• The display indication is
turned off suddenly and the
panel settings are reset.
The battery voltage is low. Replace all six batteries with new ones,
or use the AC adaptor.
Noise is produced from the EZ-
20.
When using a mobile phone, noise is produced. Using a mobile
phone in close proximity to the EZ-20 may produce interference.
To prevent this, turn off the mobile phone or use it further away
from the EZ-20.
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.
When using the Dictionary function (page 52), the keys in the right
hand section are used only for entering the chord root and type.
The auto accompaniment
doesn’t turn on, even when
pressing the [ACMP ON/OFF]
button.
When playing back one of the Pianist styles (#89–#100), the
rhythm cannot be heard. The Pianist styles have no drums or bass
- only piano accompaniment.
Not all of the voices seem to
sound, or the sound seems to be
cut off.
The EZ-20 is polyphonic up to a maximum of 16 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.
The accompaniment does not
sound properly.
Make sure that the Accompaniment Volume (page 55) is set to an
appropriate level.
The polarity of the footswitch is
reversed.
You turned on the power to the EZ-20 while pressing the foot-
switch. Turn the power off, then turn it on again without pressing
the footswitch.
