Important Advice (Electone is not necessarily out of order if...)

the unit does not go ON when the power switch

is turned ON. Check the following.

Is the AC

plug fully inserted

into the wall power

outlet?

Reinsert

it to

make

sure.

Is there .power

coming from that outlet?

If the outlet is live but the Electone does not work,

unplug the cord and contact your Yamaha dealer.

occasional unpleasant static occurs.

In the majority of such cases, the cause can

be traced to the turning ON or OFF of refrigerators,

washing machines, electric pumps or other household

appliances. Electrical faults in a neighboring outdoor

neon sign may also be a cause.

If the cause is a fault in a neon or fluorescent lighting

fixture, it should be repaired. When the cause cannot

be determined,

or in case of doubt,

contact

your

Yamaha

dealer.

` i

the Electone

reproduces radio or TV signals.

If there

is a powerful transmitter such as a

radio station in the vicinity, this can occur. Contact

your Yamaha dealer.

pedal notes sound too high, upper

keyboard

notes too low.

This

is especially noticeable

when

comparing

the

Electone and piano. Piano notes are combinations of

harmonics which are influenced by the surroundings,

whereas

Electone harmonics are simpler

(multiples

of the fundamenta!

tone)

and

require a different

kind of adjustment at the assembly stage.

rattling (sympathetic vibration) occurs.

All materials have critical resonance frequencies

at which

they

vibrate.

The

Electone's continuous

tones

will naturally

cause

other

objects

(windows,

objects on shelves, etc.) to vibrate.

Change the place of installation whenever such diffi-

culty occurs.
