Problem Possible Cause and Solution
GENERAL OPERATION
A click or pop is heard when the power is
turned on or off.
Electrical current is being applied to the instrument. This is normal.
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.
In the LCD display, there are some black
points (unlit) or white points (always lit).
Unfortunately, this is a common characteristic of TFT-LCDs.
Some buttons on the panel do not respond. The UPPER/LOWER ORGAN FLUTES and LEAD VOICE 2 buttons are invalid on the
ELS-02. If you upgrade the ELS-02 to the ELS-02C, these buttons can be used.
Some of the LEDs in the DISPLAY SELECT
section do not light.
The LEDs of on/off buttons (UPPER/LOWER ORGAN FLUTES, VOICE EDIT, RHYTHM
PROGRAM, and ROTARY SP SPEED) are lit when those functions are turned on. The
LEDs of other function’s buttons momentarily light when the functions are selected.
The sound is too small even when the
volume is set to its maximum.
• The Master Volume 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 POWER switch of the speaker may have been turned off. Turn it on.
• (For the ELS-02C) The REAR SPEAKER switch may have been set to OFF. Switch it
to ON.
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 23).
VOICES/RHYTHMS
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
14 notes. When you turn the Pedal Polyphonic mode to on, the total is 14 for all
keyboards, Upper, Lower and Pedalboard.
When sustain length is set to HOLD,
previously played notes are cut off.
Since the HOLD setting causes notes to keep sounding, the cumulative notes
(elements) may go over the maximum elements that the Electone can sound.
When this occurs, previously played notes are cut off.
