OTHER INFORMATION
Accessory Jachs
e HEADPHONE Jack
This jack is used to connect headphones (optional).
When headphones are connected, there will be no
sound from the Electone's speakers. This allows you
to play your Electone at any time without disturbing
others.
IMPORTANT: Do not use this jack for any purpose
other than headphones!
e AUX. OUT Jack
AUX. OUT
This jack is used to produce a more powerful sound by
connecting an external amplifier or other devices. If this jack
is connected to the LINE IN jack of a tape recorder, direct
recording is also possible. (Nominal Impedance: 4700)
@ EXP. IN Jack
This jack accepts a monaural signal from external ©)
musical instruments rather than tape recorder. The

volume of ће equipment connected here will be
controlled by the Electone Expression Pedal.

The MIDI (Musical Instrument Digital Interface) terminals
conform to the MIDI standard for digital electronic instru-
ments. These jacks enable you to connect your Electone to a
computer or other MIDI compatible electronic instruments for
data communication.
WARNING: The connection or disconnection of any accessory
(other than headphones) while the Electone is ON can result in
extensive damage to the Electone and/or the accessory.
Damage caused by the improper connection/disconnection of
accessories is not covered by the manufacturer's warranty.
Electromagnetic Interference
“Interference” can be a two way street; something you are
operating can interfere with others or, something someone else
has may interfere with something of yours.
Naturally, it is also possible that two or more of your own
electronic (electric) devices may interfere with each other. Your
Electone has been designed to minimize all these possibilities
and meets all applicable standards worldwide.
Electromagnetic interference with your Electone can show itself
in variety of ways. You may hear speech, music, “beeps”, static,
or buzzing sounds. Yamaha Electones are designed to reject RF
(radio frequency) signals that are many times the levels found in
any normal environment. If, however, you are in the immediate
proximity of a very high power transmitter, some interference
may still occur. If this should happen, please try to identify the
radio (TV) station and record the time of day that the
interference occurs. Station identification is essential in order
that the offending frequencies can be established and the
authorized (legal) operating power level of the transmitter
causing the interference can be verified. If the interference
continues, please follow the suggested corrective measures
provided later in this section.
If the interference is in the form of occasional buzzing or static,
it is highly probable that the cause can be traced to the turning
on or off of some household appliance. The offending appliance
can also be outside your own residence. Usually a “time” pattern
28
(i.e., evenings only, etc.) will be involved. Noises of this type rarely
orginate in the Electone itself. If the condition continues, please
contact your local authorized Yamaha Electone dealer for assistance.
Main power line disturbances and electrical storms (lightning) can
also be the source of static interference. Generally speaking
problems generated by these two sources will also be present in
your other audio or video equipment. Lightning can also be ven
destructive. The following special warning also applies to virtually
all electronic products.
IMPORTANT NOTICE
Modern electronic products, (i.e., computers, video games, electronic
organs, etc.), contain components that, under normal conditions
extend the service free life of the products they make up to а
almost unbelievable period of time. This is especially true when you
consider the vast number of equivalent components incorporate
within one given part. These “parts,” called “integrated circuits,” att
however, subject to destruction by high voltage discharges, such a
a close proximity lightning strike. This can occur even if the unit i
turned off.
IN PERIODS OF ELECTRICAL STORM PROBABILITY, IT Ë
ADVISABLE THAT YOU DISCONNECT ANY ELECTRONIC DEVICE
NOT ACTUALLY IN USE FROM ITS WALL SOCKET.
