Troubleshooting
Problem Possible Cause and Solution
When the EZ-30 is turned on or
off, a popping sound is tempo-
rarily produced.
This is normal and indicates that the EZ-30 is receiving electrical
power.
The volume level is low.
Tonal quality has degraded.
Recorded songs are not
played correctly.
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-
30.
When using a mobile phone, noise is produced. Using a mobile
phone in close proximity to the EZ-30 may produce interference.
To prevent this, turn off the mobile phone or use it further away
from the EZ-30.
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 58), the keys in the right
hand section are used only for entering the chord root and type.
The effects (Reverb/DSP/Har-
mony) are not applied.
Each effect (Reverb/DSP/Harmony) is turned off. Select a type for
each effect. (See page 48, 49, 50.)
The auto accompaniment
doesnt turn on, even when
pressing the [ACMP ON/OFF]
button.
When playing back one of the Pianist styles (#97#106), 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-30 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.
Auto accompaniment is not
played correctly.
The accompaniment volume setting is low. Refer to page 61 to
raise the volume level.
The auto accompaniment split point is set incorrectly for the played
chords. See page 44 to set a correct split point.
The polarity of the footswitch is
reversed.
You turned on the power to the EZ-30 while pressing the foot-
switch. Turn the power off, then turn it on again without pressing
the footswitch.
