Troubleshooting

Problem
GENERAL OPERATION
The sound is not heard for about 10 seconds after
turning the power on.
A cracking noise is sometimes heard.
Interference from radio, TV, or other sources occurs.
The sound of the Electone causes surrounding
objects to resonate.
Some of the LEDs in the DISPLAY SELECT section do
not light.
The sound is too small even when the volume is set to
its maximum.
The Electone panel does not function normally or the
content of the memorized data has changed.
VOICES/RHYTHMS
When a key is pressed, two or more Voices sound.
The pitch may sound excessively high on the
Pedalboard and low in the higher registers of the
Lower and Upper keyboards.
Some of the Voices may contain cracking and/or noisy
sounds.
When too many keys are pressed, not all of the notes
sound.
Only one sound is heard when two notes of the Lead
10
or Pedal Voices are simultaneously played.
The Pedal Voices do not sound, even though the
volume is properly set.
When keys are pressed, the sounds of percussion
instruments are also heard.
Even though a User button's rhythm has been
selected and started, the pattern does not sound.

Possible Cause and Solution
This is normal; the Electone takes a while to start up.
Noise may be produced when either an electrical appliance is turned on or an
electric power tool (such as drill) is used in the proximity of the Electone. If this
occurs, plug the Electone into an electrical outlet located as far as possible
from the device that seems to be the source of the problem.
This is caused by the proximity of a high-power broadcasting station, an
amateur ham radio setup or a mobile phone.
Because the Electone is capable of producing powerful bass sounds,
resonance may be caused in surrounding objects, such as cabinets or glass
windows. To avoid this, relocate the objects or lower the Electone's volume.
The lamps above the [RHYTHM SEQUENCE] button and the [SUSTAIN]
button will light up when the function is turned on in the display.
• The MASTER VOLUME dial may be set around the minimum position. Turn it
clockwise.
• The Expression Pedal may not be pressed down. Press it down with your
toe.
This happens very rarely. Occasionally, power surges and spikes due to
electrical storms or other reasons may cause the Electone to malfunction and/
or alter the contents of memorized data. If this happens, perform the Factory
Set operation to reset the Electone (page 20).
Perhaps the Voice of the Voice section 2 sounds as for the Lower Keyboard or
Pedalboard. Turn off the Voice of the Voice section 2 in the Voice display, or
set the volume setting to minimum after switching to the Voice section 2 (page
29).
As for the Upper Keyboard, the Lead Voice may sound in addition to the Voice
of the Voice section 2. Turn off the Lead Voice in the Voice display after
switching to the Voice section 2.
This may occur when you compare the Electone's sounds with that of a piano.
Because of the difference of the harmonics structure, the tuning system of the
Electone is different from the piano in the higher and lower ranges.
You may find these mainly in the wind instrument Voices. These are purposely
added effects to the Voices to reproduce the characteristics of the wind
instruments such as the pipe vibrations, breath noises and squeaks.
Total polyphonic capacity (notes sounding for both Upper and Lower
Keyboards) is 10 notes.
For practical performance reasons, the Electone has been designed so that
only one note of the Lead or Pedal Voices can be played at a time.
• The Single Finger or Fingered Chord mode of Auto Bass Chord is on. Turn
off the mode in the display (page 71).
• TO LOWER buttons in the Pedal Voice sections are turned on. Turn the
function off (page 31).
The Keyboard Percussion function has been turned on. When not using the
function, be sure to turn it off (page 77).
Since the User buttons contain User rhythms, no rhythm will sound if a pattern
has not been saved to the selected User button.
