• Use only the stand/rack specified for the instrument. When attaching the stand
or rack, use the provided screws only. Failure to do so could cause damage to
the internal components or result in the instrument falling over.
• 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.
■
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 "Battery Low" will display in the
display. When this happens, immediately back up your data using an external
device such as the floppy disk-based Yamaha MIDI Data Filer MDF3, then
have qualified Yamaha service personnel replace the backup battery.
• Do not attempt to replace the backup battery yourself, in order to prevent the
possible serious hazards. Always have qualified Yamaha service personnel
replace 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
immediately.
■
SAVING USER DATA
• Save all data to an external device such as the Yamaha MIDI Data Filer MDF3,
in order to help prevent the loss of important data due to a malfunction or user
operating 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.
PRECAUTIONS
PLEASE READ CAREFULLY BEFORE PROCEEDING
* Please keep these precautions in a safe place for future reference.
WARNING
Always follow the basic precautions listed below to avoid the possibility of serious injury or even death from electrical shock,
short-circuiting, damages, fire or other hazards. These precautions include, but are not limited to, the following:
• Do not open the instrument or attempt to disassemble the internal parts or
modify them in any way. The instrument contains no user-serviceable parts. If
it should appear to be malfunctioning, discontinue use immediately and have it
inspected by qualified Yamaha service personnel.
• Do not expose the instrument to rain, use it near water or in damp or wet
conditions, or place containers on it containing liquids which might spill into
any openings.
• If the AC adaptor cord or plug becomes frayed or damaged, or if there is a
sudden loss of sound during use of the instrument, or if any unusual smells or
smoke should appear to be caused by it, immediately turn off the power switch,
disconnect the adaptor plug from the outlet, and have the instrument inspected
by qualified Yamaha service personnel.
• Use the specified adaptor (PA-3B or an equivalent recommended by Yamaha)
only. Using the wrong adaptor can result in damage to the instrument or
overheating.
• Before cleaning the instrument, always remove the electric plug from the outlet.
Never insert or remove an electric plug with wet hands.
• Check the electric plug periodically and remove any dirt or dust which may
have accumulated on it.
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:
• Do not place the AC adaptor cord near heat sources such as heaters or radiators,
and do not excessively bend or otherwise damage the cord, place heavy objects
on it, or place it in a position where anyone could walk on, trip over, or roll
anything over it.
• When removing the electric plug from the instrument or an outlet, always hold
the plug itself and not the cord.
• Do not connect the instrument to an electrical outlet using a multiple-connector.
Doing so can result in lower sound quality, or possibly cause overheating in
the outlet.
• Unplug the AC power adaptor when not using the instrument, or during electrical
storms.
• Before connecting the instrument to other electronic components, turn off the
power for all components. Before turning the power on or off for all components,
set all volume levels to minimum. Also, be sure to set the volumes of all
components at their minimum levels and gradually raise the volume controls
while playing the instrument to set the desired listening level.
• Do not expose the instrument to excessive dust or vibrations, or extreme cold
or heat (such as in direct sunlight, near a heater, or in a car during the day) to
prevent the possibility of panel disfiguration or damage to the internal
components.
• Do not use the instrument near other electrical products such as televisions,
radios, or speakers, since this might cause interference which can affect proper
operation 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, plastic or rubber 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.
