Possible Cause and Solution
The LEDs of on/off buttons (UPPER/LOWER FLUTE VOICES, VOICE EDIT,
RHYTHM PROGRAM, and TREMOLO [FAST]) are lit when those functions
are turned on. The LEDs of other function’s buttons momentarily flash when
the functions are selected.
Noise may be produced when either an electrical appliance is turned on or off,
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.
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 Power
On Reset operation to reset the Electone. (page 83)
• 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 HOLD button may be engaged. Press the HOLD button to cancel the
Hold function and press the button again.
The currently assigned voice or rhythm is displayed at the top of the LCD, and
remains until another voice or rhythm has been selected.
Total polyphonic capacity (notes sounding for both Upper and Lower
Keyboards) is 12 notes. Polyphonic capacity is 12 for both the Upper and
Lower Flute Voices, and 6 each for the Upper and Lower Attack sound (EL-
700's Flute Voice).
Even though the Pedal voice is being played from the Lower keyboard, it is
still a Pedal voice; turn the Sustain on with the Pedal Sustain button.
Check all of the volume controls, making sure that they are set to suitable
levels: the panel Volume controls for each voice section, the Master Volume
dial, and the Expression Pedal.
Also check the Upper/Lower Balance control on the Voice Display. (page 28)
The volume of certain voices may seem lower than that of others. Adjust the
balance of the sound with the Volume control within the appropriate Voice
Condition display.
The keyboard Percussion function has been turned on. When not using the
function, be sure to turn it off. (page 68)
Problem
GENERAL OPERATION
Some of the LEDs in the DISPLAY SELECT section
do not light.
A cracking noise is sometimes heard.
Interference from radio, TV, or other sources
occurs.
The sound of the Electone causes surrounding
objects to resonate.
The Electone panel does not function normally or
the content of the memorized data has changed.
The sound is too small even when the volume is
set to its maximum.
Pressing a certain panel button doesn’t open its
related LCD display.
VOICES/RHYTHMS
When selecting a dotted button voice or rhythm,
the voice or rhythm title at the top of the LCD
does not match the voices or rhythms.
When too many keys are pressed, not all of the
notes sound.
When playing a Pedal voice from the Lower
keyboard (using the To Lower function), pressing
the Lower keyboard’s Sustain button does not turn
on Sustain.
The sound is too soft, despite the volume being
set to the maximum.
Switching voices causes the volume to change,
despite their having identical volume settings.
When keys on the Lower keyboard or Pedalboard
are pressed, the sounds of percussion instruments
are also heard.
Troubleshooting
Please note that the appearance of any of following phenomena does not
indicate a mechanical failure of the Electone.
