The sound is not heard for about 10 seconds after 
turning the power on.

This is normal; the Electone takes a while to start up.

A cracking noise is sometimes heard.

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.

Interference from radio, TV, or other sources occurs.

This is caused by the proximity of a high-power broadcasting station, an 
amateur ham radio setup or a mobile phone.

The sound of the Electone causes surrounding 
objects to resonate.

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.

Some of the LEDs in the DISPLAY SELECT section do 
not light.

The lamps above the [RHYTHM SEQUENCE] button and the [SUSTAIN] 
button will light up when the function is turned on in the display.

The sound is too small even when the volume is set to 
its maximum.

• 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.

The Electone panel does not function normally or the 
content of the memorized data has changed.

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).

When a key is pressed, two or more Voices sound. 

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. 

The pitch may sound excessively high on the 
Pedalboard and low in the higher registers of the 
Lower and Upper keyboards.

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.

Some of the Voices may contain cracking and/or noisy 
sounds.

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.

When too many keys are pressed, not all of the notes 
sound.

Total polyphonic capacity (notes sounding for both Upper and Lower 
Keyboards) is 10 notes. 

Only one sound is heard when two notes of the Lead 
or Pedal Voices are simultaneously played.

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 Pedal Voices do not sound, even though the 
volume is properly set.

• 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).

When keys are pressed, the sounds of percussion 
instruments are also heard.

The Keyboard Percussion function has been turned on. When not using the 
function, be sure to turn it off (page 77).

Even though a User button’s rhythm has been 
selected and started, the pattern does not sound.

Since the User buttons contain User rhythms, no rhythm will sound if a pattern 
has not been saved to the selected User button.
