PRECAUTIONS
PLEASE READ CAREFULLY BEFORE PROCEEDING
* Please keep this manual 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:
•Only use the voltage specified as correct for the instrument. The required
voltage is printed on the name plate of the instrument.
•Use the specified adaptor (PA-3C or an equivalent recommended by Yamaha)
only. Using the wrong adaptor can result in damage to the instrument or
overheating.
•Check the electric plug periodically and remove any dirt or dust which may have
accumulated on it.
•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.
•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.
•Never insert or remove an electric plug with wet hands.
•Do not put burning items, such as candles, on the unit.
A burning item may fall over and cause a fire.
•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.
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:
•When removing the electric plug from the instrument or an outlet, always hold
the plug itself and not the cord.
•Unplug the AC power adaptor when not using the instrument, or during
electrical storms.
•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.
•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 in the vicinity of a TV, radio, stereo equipment,
mobile phone, or other electric devices. Otherwise, the instrument, TV, or radio
may generate noise.
•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.
•Use only the stand 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 place objects in front of the instrument's air vent, since this may prevent
adequate ventilation of the internal components, and possibly result in the
instrument overheating.

PRECAUTIONS
ENGLISH

•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.
•When cleaning the instrument, use a soft, dry cloth. Do not use paint thinners,
solvents, cleaning fluids, or chemical-impregnated wiping cloths.
•Never insert or drop paper, metallic, or other objects into the gaps on the panel
or keyboard. If this happens, turn off the power immediately and unplug the
power cord from the AC outlet. Then have the instrument inspected by qualified
Yamaha service personnel.
•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.
•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.
Saving and backing up your data
•Depending upon the Backup Functions (page 42) settings, internal data is
retained for about 1 week after the power is turned off. If the period is exceeded,
the data will be lost. Be sure to turn the power switch on for a few minutes at
least once a week. The data could be lost due to malfunction or incorrect
operation. Save important data to external media such as the Yamaha MDF3
MIDI data filer.
Backing up the external media
•To protect against data loss through media damage, we recommend that you
save your important data onto two external media.
Always turn the power off when the instrument is not in use.
Even when the power switch ([STANDBY/ON] switch) is in the “STANDBY” position, electricity is still flowing to the instrument atthe minimum level. When you are not using
the instrument for a long time, make sure you unplug the AC power adaptor from the wall AC outlet.
Make sure to discard used batteries according to local regulations.

Features
The Yamaha P-90 Electronic Piano offers unmatched sonic realism and natural grand-piano type playability as well as
Yamaha’s original “AWM Dynamic Stereo Sampling” tone-generation technology for rich, musical voices, and a special
“Graded Hammer” keyboard that provides graded key weight and response throughout the keyboard range.
The GrandPiano1 and 2 voices feature samples recorded from a full concert grand piano. The GrandPiano1 voice features
three velocity-switched samples (Dynamic Sampling), special “Sustain Sampling” that samples the unique resonance of
an acoustic grand piano’s soundboard and strings when the sustain pedal is pressed, and “Keyoff Samples” that add the
subtle sound produced when the keys are released. The P-90 comes much closer to the sound of a true acoustic piano.
