Incorrect operation and ignorance of the proper operating procedure are sometimes mistaken for trouble. [f you call in a serviceman in any of the cases given below,

it will be charged to you even if the warranty period is still effective.

"Trouble"

Cause

Remedy

Electrical "trouble"

No sound heard immediately after the power switch is

turned on.

It takes about 5 seconds for the Electone Organ to

become fully operational.

The Electone Organ is working properly and therefore is

not a cause

for concern.

Frequent noise.

TV or radio reception quality is degraded when the

Electone is turned on.

Occasional interference from radio or TV broadcasts.

(1)

Noise is caused when home electrical appliances such

as refrigerators and washing machines are switched on

and off.

(2)

Failure in neon sign in your neighborhood or electric

drill, etc.

The radio or TV set is being used in the immediate

vicinity of the Electone Organ.

A broadcasting station with a high signal strength or an

amateur radio station is located nearby.

(1)

Use a power outlet which is located the furthest

from the appliance which you suspect to be the

origin of the noise.

(2)

Have the neon sign repaired.

(3)

If you cannot locate the origin of the noise, get in

touch with your dealer.

Move the radio or TV set as far away from the Electone

Organ as possible. Upgrade TV or radio antenna system.

Try to identify the type of station: TV, FM radio,

AM radio, "Ham" operator, CB operator, etc.

Fluctuations in the sound volume, depending on the posi-

tion of the organ. Varies somewhat depending on the voices

selected.

Since one of the foremost features of an electronic musical

instrument is the capacity to change the tone color, it is

extremely difficult to even out the fluctuations in the sound

volumes of each keyboard caused by the tone colors. How-

ever, the Electone Organ is designed and adjusted to pre-

clude any such problems during actual performances what-

ever the tone color.

The sound level and the tonal character will vary accord-

ing to the installation location of the Electone Organ and

the listening position. Try various locations within the

room.

Only one note is heard even when two pedal keyboard or

solo keyboard keys have been depressed.

Only seven notes are heard even when more than seven

keys on the upper or lower keyboards are depressed,

The Electone Organ is designed so that only one note from

the pedal keyboard and solo keyboard and seven notes each

from the lower and upper keyboards can be sounded.

This is because of performance and design considerations.

The high notes are given priority with the pedal and solo

keyboards while the keyboard whose key has been

depressed first is given priority with the upper and

lower keyboards.

Handling "trouble"

Noise is heard when the Electone Organ is subjected to

vibration or shock.

The built-in reverberation unit employs a soft spring and

so vibration is transmitted.

(1)

Take care not to subject the Electone Organ to strong

vibration or shock.

(2)

Install the Electone Organ so that it does not shake.

(3)

When moving the Electone Organ, switch off the power

or rotate the reverberation control to MIN, that

the reverberation effect is not produced and then move

the Electone Organ,
