PLEASE READ CAREFULLY BEFORE PROCEEDING
* Please keep these precautions in a safe place for future reference.
CAUTION
Always follow the basic precautions listed below to avoid the possibility of physical injury to
you or others, or damage to the instrument or other property. These precautions include, but
are not limited to, the following:
• If the instrument is not to be in use for a long time,
remove the batteries from it, in order to prevent pos-
sible fluid leakage from the battery.
• Keep batteries away from children.
• Before connecting the instrument to other electronic
components, turn off the power for all components. Be-
fore turning the power on or off for all components, set
all volume levels to minimum.
• Do not expose the instrument to excessive dust or vi-
brations, or extreme cold or heat (such as in direct sun-
light, near a heater, or in a car during the day) to pre-
vent the possibility of panel disfiguration or damage to
the internal components.
• Do not use the instrument near other electrical prod-
ucts such as televisions, radios, or speakers, since this
might cause interference which can affect proper op-
eration of the other products.
• Do not place the instrument in an unstable position
where it might accidentally fall over.
• Before moving the instrument, remove all connected
adaptor and other cables.
• When cleaning the instrument, use a soft, dry cloth.
Do not use paint thinners, solvents, cleaning fluids, or
chemical-impregnated wiping cloths. Also, do not place
vinyl or plastic objects on the instrument, since this
might discolor the panel or keyboard.
• Do not rest your weight on, or place heavy objects on
the instrument, and do not use excessive force on the
buttons, switches or connectors.
• Do not operate the instrument for a long period of time
at a high or uncomfortable volume level, since this can
cause permanent hearing loss. If you experience any
hearing loss or ringing in the ears, consult a physician.

PRECAUTIONS
REPLACING THE BACKUP BATTERY
• This instrument contains a non rechargeable internal
backup battery which permits internal data to remain
stored even when the power is off. When the backup
battery needs replacing, the message "Backup Batt.
Low" will display in the LCD panel. When this happens,
immediately back up your data (using an external de-
vice such as the floppy disk-based Yamaha MIDI Data
Filer MDF2), then have qualified Yamaha service per-
sonnel replace the backup battery.
• Do not attempt to replace the backup battery your-
self, in order to prevent the possible serious hazards.
Always have qualified Yamaha service personnel re-
place the backup battery.
• Never place the backup battery in a location that a child
can reach, since a child might accidentally swallow the
battery. If this should happen, consult a physician im-
mediately.
SAVING USER DATA
• Save all data to an external device such as the Yamaha
MIDI Data Filer MDF2, in order to help prevent the loss
of important data due to a malfunction or user operat-
ing error.
Yamaha cannot be held responsible for damage caused by
improper use or modifications to the instrument, or data that
is lost or destroyed.
Always turn the power off when the instrument is not in
use.
Make sure to discard used batteries according to local
regulations.
