Yamaha Electone FE-40 - Using Your Electone: Useful Information; Accessory Jacks; Electromagnetic Interference

III. USEFUL INFORMATION ABOUT USING THE ELECTONE
[ACCESSORY JACKS]
Several jacks have been included in the design of your
Electone in order that a variety of optional accessories
may be used.
@HEADPHONES Jack
This jack is to be used to connect monaural 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.
NOTE: You can also use stereo headphones in this jack
without damaging either the Electone or the headphones.
IMPORTANT: Do not use this jack for any purpose
other than Headphones!
€ AUX. OUT Jack
This jack has been provided to permit connection of your
Electone to most tape recorders that have a “Line In” jack.
This allows a direct recording without any outside noise.
@AUX. IN Jack
The “Aux. In” jack can be used to connect most tape re-
corder/players having “Line Out” jack. This permits you
to play back recordings through the Electone’s speaker
system. By using this jack, you can also perform together
with previously recorded music.
NOTE: The sounds reproduced utilizing this jack is not
controlled by the volume pedal.
ФЕХР. IN Jack,
This jack accepts a monaural signal from synthesizers or
similar accessories (designed to provide approximately 2
vpp [two volts, peak-to-peak] into a 10k ohm load). The
volume of the equipment attached here will be controlled
by the Electone Expression Pedal.
WARNING: The connection or disconnection of any ac-
cessory (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 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 some-
one 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 pos-
sibilities and meets all applicable standard worldwide.
Electromagnetic interference with your Electone can show
itself in a variety of ways. You may hear speech, music,
“beeps?’ static, or buzzing noises. 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 con-
tinues, please follow the corrective measure suggestions
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 (i.e., evenings only, etc.)
will be involved. Noises of this type rarely originate in the
Electone itself. If the condition continues, please contact
your local authorized Yamaha Electone dealer for as-
sistance.
Main power line disturbances and electrical storms (light-
ning) 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 very destructive. The
following special warning also applies to virtually all elec-
tronic 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 by an almost unbelievable
period of time. This is especially true when you consider
the vast number of equivalent components incorporated
within one given part. These “parts,” called “integrated
circuits,” are however, subject to destruction by high
voltage discharges, such as a close proximity lightning
strike. This can occur even if the unit is turnes off.
IN PERIODS OF ELECTRICAL STORM PROB-
ABILITY, IT IS ADVISABLE THAT YOU DISCON-
NECT ANY ELECTRONIC DEVICE NOT ACTUAL-
LY IN USE, FROM ITS WALL SOCKET.
